Part 3 of Opimizing Adsense Revenue: Relevant Ads

Today I skimmed over Problogger's tips to making sure the ads on your site are relevant (i.e. they are in line with the blog content and therefore optimize on adsense revenue). Here are some things you can do to make sure adsense gives you relevant ads:
1)Increasing key word density: Once you have gone through the process of identifying keywords that produce high paying ads, make sure to include the key words in the title, first pargraph and sprinkle it throughout the article making it bold,underlining it etc.
2)Check your articles, sidebars, headings etc to make sure that you're not regularly using keywords that have nothing to do with your blog topic.
3) Block irrelevant ads.
