Two weeks ago I replaced my Adbrite ads for Adsense ads. The Adbrite ads were performing very bad and I decided to give Adsense a chance. Adbrite made a little over $5 in 15 days, while adsense now made $10 in the last 12 days. Conclusion: Adsense is performing better on my website (I am sure there are websites were Adbrite performs better than Adsense)!
This ad tweaking is important to get the maximum revenue out of your website. The website I made these changes to is a site with themes for Sony Ericsson! Currently it is only running Adsense! Might get some new CPM banners in, as it generates a lot of pageviews. The CPM banners from Adbrite are not working on this site!
I am also getting more into the SEO world. This always interested me and I had decent results with a couple of websites some time ago! Just got my first customer to SEO his website and started with the link building 
It all comes back to SEO and it’s all about the links.
Did I say links…
