The reality about high paying adsense keywords is that they are quite simply very difficult to come across. The probability of your adsense ads being very high paying that is pay over a dollar a click is quite slim simply because the number of advertisers that make huge bids is slim and even if they do get clicked on, google’s smart pricing algorithm may not give you that much money in the first place.
Thus instead of searching for those extremely high paying keywords you are better off focusing on niches that have heavy advertiser competition. The point is that the heavier the advertiser competition the higher the average bid will thus the higher adsense payout you will receive. An example of some of these niches with heavy advertiser competition include the ‘internet marketing’, ‘insurance’ and ‘mortgage’ niches.
The idea is to make more money with adsense so focus on improving your site’s click thorough rate rather than looking for those hard to get high paying clicks. You can improve your adsense ad click thorough rates in many ways. One of the keys is ad relevancy. You need to ensure that your adsense ads are displaying ads that are related to the content on that page. A great tool you can use to check this is the adsense preview tool which is available from google themselves.
Also your adsense ads need to blend in as much as possible with your content. You are not trying to deceive your visitors but rather you simply want your ads to be noticed and not ignored as most ads are. If your ads are relevant and they are being noticed there is a good chance they will get clicked on. Removing the borders from your ads helps to blend them in with your site. Most people recognize the borders immediately and associate an ad to them and so they ignore it. Also using the right colors is important for your adsense ads.
You do not want your ads to stand out in any way, so use the same link color in your ads as the links on your site. Also try to get the text size on your site to match the adsense ad text size as closely as possible. This will also help to blend your ads in with the rest of your site. Using the right adsense format sizes is also important.
You want to avoid the banner adsense format as it has been proven to be the worst performing. Also, unless your site is a pure directory structured site that user will want to use a search feature for, I suggest you not use the search box as the amount of money made from that feature is not that great.
You are better off adding another link unit instead. Make your link units fit into the natural navigation structure of your site and again make the link color the same as the rest of the links on your site. These are a few adsense tips to help you make more money not just by getting more higher paying ads but by also attracting more clicks from your site.
