It looks obvious

Here is a disturbing Idea:  it is more beneficial to search companies not to fix the increasing inaccuracies in search results.  

I’m finding that more and more I click on ads rather than search results at Google. Why? Because the search results in some commercial categories are so thoroughly SEO (search engine optimization) spammed that it’s a waste of time trying to figure out which search results are worth clicking.

But while the search results are a mess, the people who pay to have their ads run are often worth clicking. After all, they’re bidding and paying for my attention, thus making them more likely to be worth a scan than some SEO-optimized Adsense site that has thrust its way into the top ten pure search results.
