Why Advertisers support Adsense?

Google is the biggest search engine on the web. It controls over 40% of Internet searches, and with that it controls pay per click advertising (pay per click). PPC involves the advertiser paying a rate for every click through (CTR) in which the advertisers set. As their budget increases, their position increases, and as their position increases, they get more traffic.

This has lead to over 140,000 companies choosing to advertise with them, and they advertise in a number of ways. The first way is through is through appearing on Google searches, the second is through appearing on distributors websites, and the third is through appearing in distributors search results. As advertisers appear in Google searches, the question is sometimes asked. Why do they choose to advertise with distributors as well?

One reason for this is scalability. Those who originally choose to advertise in search results and who were getting a ROI (return on investment) will decide at one point that they need to identify other advertising opportunities. With thousands of websites which have the capacity to display their adverts the advertisers can gain further exposure very quickly.

Another reason why advertisers choose to advertise in Google distributors websites is that it gains them further exposure. 60% of internet users do not use Google, so the advertiser can appeal to a wider audience through choosing to opt for distribution channels. Many website users may be looking to buy a product such as a phone, yet instead of coming across a website which sells such a product, they come across an article. If the article is on a website which contains Adsense then inevitably advertisers can use this channel to penetrate their audience.

Another reason why advertisers choose adsense is because they trust Google. The company is renowned for being an ethical company who are fun to work whilst providing free services to millions worldwide. Advertisers feel that money invested with Google is safe. Despite the evolution of click-fraud and its inevitable disadvantages for advertisers they appear to understand that this is an issue which Google wants to stop and hopefully will eventually. Advertisers are happy that Google admits a problem exits and provides refunds accordingly.

The trust in Google also stems from a trust in pricing. The pricing is set by market forces and therefore advertisers never feel that publishers or Google are overpricing the service. This means that as long as advertisers are able to advertise they will continue to do so, if not at the same rates.

Another strong advantage for advertisers is that they can appear where publishers promote their service. An example of this can seen if you consider a publisher who is discussing the benefits of new IT software. If a software retailer appears on the website then inevitably they will be the likely source from which the web surfer will purchase the product. If the surfer is not interested then you could argue that they would not click on the advert.

The service which Google provides has created an opportunity for businesses of all sizes to advertise. Although the issue of click fraud still plagues the service it is till widely regarded as the best. New businesses attempt to promote themselves on the web, whilst established brands alike choose to attract interest in their service using the same technique.

Top Paying Keywords

In people's search for higher incomes from Google AdSense a lot of AdSense publishers are looking to find those keywords that really bring the best income possible. The higher an advertiser pays for a keyword, they more the advertiser receives when they click on a link.

But how can you find such words for your site? Well, the answer to that question depends a little on who you are and what you're prepared to do to get those keywords. But the general good news is that you can indeed find such words if you need them.

Of course, if you can afford such a solution, one of the best ways of getting your hands on those words would be to pay for them. There are specialized companies that do business by finding people good keywords, not only for the purpose of more AdSense revenue but for search engine optimization as well.

Such a service can be found on "Top Paying Keywords" http://www.toppayingkeywords.com/?hop=moneymkr and this is a no-brainer to getting relevant content on your site and increasing your revenue by a whole bunch quickly.

Of course, if such a solution does not work for you, you can ultimately resort to a method of personal investigation. That means you try out keywords by yourself and see which ones work better or worse for yourself.

While you might also be doing this for the first method (paying someone else to get the keywords) it would probably be better then this because you'd at least be narrowing down search to certain items.

While you're trying this make sure to keep using AdSense's 'channels' feature along the way as it can be a very good way of letting you know which sections of your site are generating income and which aren't.

Of course, you can also yield a great amount of help from AdSense's arch enemy Overture. Overture gives you the possibility of entering keywords and finding out not only how much advertisers are paying to get them on your page, but how much people are clicking on the words as well. This service can be found at: http://www.pixelfast.com/overture/

You can also try out a tool called Word Tracker http://jeremyburns.com/a/wordtracker. What this tool can do is tell you how many sites are already using the same keywords. Learn from this lesson and don't try to use the words that a lot of people are already using.

Also, a great aid may very well be found in Google itself. Search Google for any keywords you may wish to include in your pages and look at the results. The results on the left will probably be your competitors (and if they have Google AdSense ads on their page you can bet then are) while the links on the right display ads relevant to your search.

If your search doesn't yield any AdSense results then you might want to reconsider including those keywords in your site.

Make sure you don't use any dead words (words that don't get any links on AdSense other then public ads. That is probably the most important thing you should be doing.

Of course these are only a few methods of getting out of the dead zone and starting to make serious money with AdSense. If you've seen a lot of people with "not so hot" websites generating a lot of AdSense revenue, using these tips can get you right behind them (or in front if you're really smart) very fast. Although this is the case it is also very important to remember that having the highest paying words does not mean that you make the most money. You have to also consider how many times the advert is clicked on.

How Much Money Will I earn Through Adsense?

If you're looking at Google's AdSense program you're surely asking yourself how much you could make from such a program, and you probably think you can't make as much as you can from traditional advertising schemes.

Google, of course, keeps a great deal of secrecy regarding how much AdWords advertisers pay per each click directed to their site and the same applies for how much AdSense banner holders make from their websites.

While there's nothing official, rumors circulate around the Internet concerning the amount of cash a website can earn by using AdSense. And many people (illegally) disclose how much they have been making with AdSense. There are stories of people raising over one thousand dollars per month using AdSense.

There are also stories of people exceeding $100,000.00 per month but it's a bit hard to believe such stories. The truth to the matter is that if you have a small website and you just want it to support itself, and don't wish to reach your pocket for its maintenance costs you can probably do this with AdSense.

AdSense is also very good for people who host a lot of pages. Even if the said pages don't generate a lot of traffic individually, every click counts and you can earn up with a lot of money by doing this. And that just goes to prove that sometimes quantity matters nearly as much as quality.

There's no telling how much money you're going to make by using Google's AdSense but you can sort of tell for yourself, before actually starting, by taking a few things into consideration.

First, is the amount of visits you get every day. While there's no way to estimate precisely on this, you can generally make a safe assumption that if you have a lot of clicks per day you'll be making good money.

Also, this depends on what exactly your site is about. If your site is about anything popular (music, sex, whatever) you're bound to get a lot of banner clicks. These have a coefficient associated with them, called the CTR (click through ratio).

Basically, what it translates to is that if a large proportion of your site's visitors click the ads you'll be making more money. And the best way to do this is to have some popular content in your site, ensuring the links direct users towards popular items as well.

Then of course, there's the position and number of ads on your website. While you don't want to overdo it, having many links will undoubtedly generate more income for you as a webmaster. Do not however believe, that if you just add a lot of ads in an important portion of your site, visitors could always just skip them (and be assured that many do just that).

There's something between an art and a science to positioning your ads. People generally look in certain places and never look in others, and knowing this a website author and/or webmaster can do a great deal of things to increase his earnings with AdSense.

All in all, the amount of money you make with AdSense depends on many factors. But if you have a site with interesting contents and/or many pages, and if you see a constantly large amount of traffic every day, you can bet you'll be making a lot of money with AdSense.

Even if you aren't in the above categories, AdSense is still worth using because there's very little hassle in setting it up, and many times it can help financially support the site, whilst being a nice bonus to get through the post at the end of the month.

Adsense and Surfer

AdSense is an easy program to grasp: it's a great form of an advertising bringing a lot of benefits to every person in the chain. And of course, seeing the results it can have on a business (and a publisher) people encourage this form of publicity.

For the browsing audience this is probably the most straightforward model available, because they can be directed to a lot of new sites they wouldn't have otherwise found. Needless to say, if you have an AdSense banner on your site, and a large number of visitors you'll know it offers a great financial benefit.

But why does it work for the people clicking the links, as opposed to a standard approach?

It is aided by today's society. With bloggers and information based articles on the internet, people may be encouraged to complete purchases, which adsense can provide links to relevant suppliers whilst also benefiting the publisher.

And the good thing about this is that it works for site visitors as well. In fact Google realized that by pleasing the people who are looking for something, and directing them to what they need faster, everybody wins.

 It is because of this that a lot of websites promote through AdSense in both content and search. They do it because they ultimately learned that it works for everyone.

If we look in the past, we can realize that this kind of publicity has a great impact over the people, especially in the last few years. When we enter on a web site and we see a graphical banner, our first idea is to cancel it out of our mind, because it's of no concern to us.

That's why traditional banner advertising is wrong. It's precisely because people are becoming savvy that they don’t look at a flashy banner because they think they'll be losing their time with it.

We've gotten accustomed to banners that don't interest us. And we're accustomed to them having nice graphics. So we naturally associate the two things and think that a banner with nice graphics has nothing to tell us.

But we might look at a text-ad because we've grown accustomed to them being targeted at what we're looking for. Basically these advertisements have marketed themselves into being looked at by any visitor.

This is a typical "no fluff, just stuff" situation. And in the end it means the visitors will see what they're interested in, not some random cool graphics you throw at them.

As stated above, site visitors adopt this advertising mechanism, because it is efficient in leading them to pages of interest and can offer ton of things they really want to see. Someone coming across an article on adsense was probably looking for shoes or doing research on shoes when they came across the article.

And most importantly for everyone, including visitors, this scheme can only improve as the process gets further refined to make ads more relevant to what you're looking for, not just a couple of keywords on a site.

Nowadays, it is because of AdSense that Internet surfers are looking after more interesting related things from banners, and the companies behind the site (Google and the advertiser) need to have better ideas to display, as expectations have increased a great deal.

So could "Do no evil" actually work in today's cut throat competitive marketplace? Well, as you can see it can and it does. And you, as a visitor are the one who gets to enjoy this the most. Advertising becomes less of a burden and more of a benefit, and is still a benefit you can choose to ignore.

Less obtrusive banners; banners that you're actually likely to be interested in and click means you'll be less annoyed by surfing the web and feel like you as a visitor being offered a relevant service.

Although some may feel reluctant to read articles that are there purely to compel consumers, undoubtedly without this consideration they are useful. Ultimately the adverts mean that you don’t have to go back to your homepage every time you are compelled to complete a purchase.

Why Use Google AdSense?

Undoubtedly, you've heard about Google's AdSense and you are thinking about giving it a go. But is it really worth placing an AdSense banner on your site?

The answer is a definite yes. You could always have some other banner on your site, or even use some search of affiliate ad program and that would probably make you some money, given of course that your site enjoys a healthy amount of visitors. However with affiliate marketing, it is expected that the visitor from your website completes a sale before you are remunerated.

But that's nowhere near what you get for using AdSense. There are people who earn in excess of 100.000 dollars per year by using AdSense. And it doesn't just stop with making more money. Firstly, the ads are text only. That means they're by far less obtrusive on your visitors then your average, flashy banner that's designed to catch the eye of the visitor.

Sure, you'll have to ensure they get better placement, so as to be noticed but despite that they don't bother viewer’s as much as traditional ads. Think about the many sites you've seen using pop-ups, floating banners and many other schemes that will have visitors screaming in anger every time they visit the said website. You can actually do better then that, annoying people less and still making an amount of money.

Secondly, the ads are generated based on the contents of your site automatically. When you use an affiliate ad program, you have to specify certain categories that your sites belong to.

However, if any page on your site falls outside of these categories, the banners aren't targeted anymore. And what that means is that you're potentially showing ads to people who don't have any interest in them and that can lead to inefficiencies.

With Google AdSense that just about never happens: the ads present on your site will always be in sync with whatever your visitors are interested in and that adds to your site's value and to the revenue it produces.

What's more, the look of these banners and their size is customizable, which means they will feel more integrated with the rest of your site's content, which brings an increase in your site's overall visual quality as opposed to a traditional approach.

For many people, there's also a great problem with finding people to advertise on their site as well. AdSense is clearly the easiest solution available to this problem today.

It's free to join the AdSense program and it almost takes no time at all. The potential database of websites from AdWords is larger then anything you might encounter from any competitor, numbering over 150.000 users. This means as more people compete the CPC or cost per click for search terms will inevitably rise.

Also, setting up AdSense on your site is a breeze, and you can complete the whole process in less then an hour. It takes a lot less to do then any form of affiliate advertising which is yet another reason to choose the easy AdSense approach.

All you need to do is add an AdSense banner on your website (other then registering with the program of course) is to copy & paste a few lines and you're all done, you get to choose where the banners go, how large they are and how they integrate with the rest of your site.

For any webmaster out there, that's a killer scheme because it lets you draw the line between your site's usability level and the amount of advertising you wish to have. Some people need the money badly while others just keep AdSense running to pay for the hosting of their website.

AdSense is a great advertising program because a lot of thought has went into making it "just work for everyone". It works great for the people who use AdWords, for the webmasters using AdSense, and most importantly for the visitors of the websites.

Getting Started With Adsense

A very important element in the rapid adoption of AdSense is that it has been very easy for publishers to get the ads on their site as quickly as possible.

Integrating AdSense in your website takes only a few minutes, and you can be on your way with one or more nicely integrated AdSense ads.

The first thing you need to do is navigate to http://www.google.com/adsense and either apply or log in with your existing account and password. What follows is a page presenting the Google AdSense Terms and Conditions which you must agree to in order to proceed.

You are presented with a report page which you can use to get a detailed status on how your AdSense advertising is doing. This allows you to improve your site's contents and layout to maximize your AdSense earnings.

On the top of your page you also have link to the setup section where you can generate the code that will need to be pasted on your website in order to have AdSense banners on your page.

You can use AdSense for text (the said ads), using a search box or with referrals. Your choice among these options depends on how users will navigate your site.

Finally, there is a "My Account" tab which allows you to set up details concerning your account, payment and tax information.

To add a text ad on your site, go back to the "AdSense Setup" tab and click the "AdSense for content" link. Make sure you have cookies enabled in your browser.

You can make a choice between ad units and link units. The former contain text and or images concerning a certain site for each unit, most with a detailed description, the latter only contain links to certain types.

Of course, it's a bit hard to know which type you should use so you should probably experiment with both for a while before you decide.

You can also view an example of how the unit will look to the right of your page. However, you may only use three ad units and one link unit on any given page. This is believed to be a step which Google takes for quality control.

The next step is to choose your add format and colors. You can basically select any color palette you choose with Google offering some of its own if you don't have the time or skill to create one. You can constantly view how the palette will look through the aid of an example. The one that works best in terms of appearance and revenues will vary with the look, feel and content of a website.

However, your ad formats are limited to a choice of eleven formats. There's an "Ad Formats" link which takes you to a page that lets you see all even of these in action so you can decide best which one suits your site. Sometimes the most intrusive, doesn’t work best however again, this can vary from website to website.

After you finish with customization, you can click "Continue" from the bottom of the page.

You are now presented with a section entitled "AdSense for Content". You can click anywhere in the text and that shows the JavaScript required to get AdSense running. This will automatically select the text in the box.

You can then copy it and paste it into your pages directly. If you use dynamic pages, you should paste this code within your template so as to ensure that it gets displayed on any page of your website. Some advertisers choose not to display Adsense on every page, and this is understandable. An example of this is a company that has adsense, may also have terms and condition which would inevitably provide legal resources which would probably be deemed inappropriate.

What is then left for you to do is get content on your page (provided you didn't have any already). Google AdSense crawlers will soon visit your site, making sure that the ads displayed are relevant to your site's content.

And you're all done. For a simple page this should indeed be a matter of a few minutes, which is precisely what makes AdSense the choice for so many. Although it is quick, its mass appeal also makes it the best. Through being the most popular, advertisers and publishers alike see Adsense and Adwords as their natural first choice.

What is Google AdSense?

What is Google AdSense?
If you look at the Internet a few years back, you'll see that advertising was done in a way that was very similar to other types of media like television, or actually, more like what you see in a newspaper.

You'd enter a site, and in some location you'd get to see a banner (often these were quite numerous and very large), which would present and ad for whatever company was paying for adds on your space.

But there was one problem with this kind of advertising. It really wasn't exploiting the fact that the adds weren't in some newspaper, but were instead presented over the Internet.

You've probably noticed a lot of things like this over the pages you've browsed. You're looking at an on-line shop, looking for a watch but you get a banner that advertises a car.

While you might, at some later point want to buy a car, right now you're looking for a watch and it would have surely been nice if the banner were advertising a watch, because then you would have probably clicked it.

Well that's also what the folks at Google thought of, so they came up with a killer idea. This is knows as Google AdSense, and it's known as a targeted advertising program

What you do (as a web designer / website owner) is, instead of jumping through hoops to get some banner on your site that your visitors won't even care about, is you just allocate some region of the screen.

You then sign up for the Google AdSense program, you insert a small snippet of code in your webpage and Google ensures that in the location you specify, a banner will appear, presenting adds relevant to the contents of your site.

It's very easy for Google to do this because Google is a search engine company. It looks for the key words in your page, searches a database of websites to find the ones related to whatever is on your page and presto: a targeted ad.

You (the webmaster) get a fee for each visitor that clicks on an adsense banner on your site. Now that's bound to happen more often then with a traditional banner because people are actually interested in what's in that banner (otherwise, they wouldn't be on your page would they?).

But, this also does wonders for the people who want to advertise. And it's because of the same reason. The greatest thing about Google AdSense is that all the content in a banner is relevant.

This relevancy is the key to the programs success, and also the reason why everyone remains happy. The advertiser has a relevantly placed advert, the publisher earns money from their content and Google take their cut.

Of course, as always, Google has set some high standards for its AdSense program, in terms of looks and functionality. You can't have more than two such banners on your website and Google only inserts text in these banners.

So an extra benefit is that AdSense advertising is a lot less obtrusive then regular advertising. But this also means you should position the banner better because it's possible that visitors might miss it altogether.

So in the end, Google AdSense is an advertising program that is unique because the ads are relevant to the content on the site. Anyone that wants to advertise pays Google for it. Anyone who wants to place ads on their site does this through AdSense, getting paid by Google in the process.

All transactions are run through Google, and the advertisers and publishers get access to statistics which help them to understand and moderate the effectiveness of their campaign.

The whole process is elegant, simple and effective from anyone in the chain, from site visitors to advertisers, and it's one of the reasons Google are known for their innovation and new thinking.
