I know there are techniques to raise click amounts but I was wondering if anyone has solid evidence that bigger companies pay less or anything like that would help increase click amounts? Thanks.
It's not about bigger companies. It's about the companies that purchase a lot of ads, like eBay for example. Most eBay related clicks end up somewhere around a single cent. As they say, AdSense calculates the most fruitful option of showing ads. I guess it only shows eBay ads when there isn't anything higher paid to be shown.
I'm not sure they do, at least not based upon my tests. Or, "most fruitful" doesn't mean highest-paying.
It's a combination of factors - what the Googlebot deems to the higher paying ads AND with the highest CTR gets placed higher. As to your question, unfortunately the size of the company does not indicate whether they are generous Adwords bidders. Use Adlogger to do calculations and research on your own data (it tells you where the clicks go to) then you'll know what companies in your niche are the higher paying ones.
Exactly, site specific. I suspect it's based on a relevance factor and THEN a price factor. Since some of these MFAs involved in arbitrage are getting pretty good at writing ads that would SEEM to be really specific and really targeted to your site, you may get a whole plethora of them showing up, and they be worth $0.01 to $0.02 per click. When I discover them and apply the filter to them, very nice changes happen
@Adpubster: hahah I do that myself but so far, I've only raised the floor minimum up to 5c. Gotta get them higher!
LOL, I thought so, too, and had filtered them for a while. They are not totally worthless, though, i've found out, and occasionally come through with some very decent clicks for me.
