It seems my comment confuse the other. Maybe I should write it with clear description. Infolinks always trying to show higher ads in every sites. Most of the times, visitors wouldn't hover their mouse to all of the articles which mean not even single ads will be shown to visitors (zero earning). I have a policy not to bombard my visitor with ads. Especially the un-targeted ads. If I have to place ads, The visitors should think it as great addition. I limit the infolinks ads in each page at 3-5. I prefer 3 ads per page which mean only three links per article. 99% Visitors wouldn't hover their mouse to the whole articles. It wasn't a problem for me. I didn't like my articles cluttered with ads. 3 links are acceptable for me. It only give me small amount of money from advertising. Then I implement 'related tags' and use it exactly at the best spot in my site. The visitors will enjoy reading the article (with three links). Their mouse hardly hover in the ads. However, after they reading it, they will scroll down the page and looking for related articles. This is how 'related tags' play an important roles. Place it below the articles where the mouse will pass it. Visitors will hover their mouse and ads will show up. They have two choices, To read the articles in my site or visiting others site which have related content with my sites (through infolinks ads). It is win-win solution. "Always show ads in the right place for the right people". It will make both Advertiser and Visitors happy. In the end, We as publisher and also Infolinks as our ads network will get the positive result too.
By saying "Always show ads in the right place for the right people" I was referring to ads placement below the article. More than half of visitors would not seeking for more related articles. Few of them will try to seek for more articles by moving to lower page. I consider people whom trying to seek more related articles as 'the right people' or prospective customer for advertiser. Advertising is a unique case. Showing too many ads and bad placement will result in visitors hate our site. Referring 'the wrong visitors' to advertiser would make them pay us less (Low Conversion). Showing less related ads with very good placement will make visitors like our site and the ads. They would think it (ads) as premium addition for the site. Referring low visitors that may purchase the product is better (high Conversion). Advertiser willing to pay more for visitors would buy their products.
Arick, what an explanation and idea ! Let me implement your idea and will inform you any change in revenue later.
While it works for me, I have no guarantee it would work for the others. I wish it work for you and hope it increase your eCPM and earning. Lets always share the method to help others.
