Early versions of search algorithms relied on webmaster-provided information such as the keyword meta tag or index files in engines like ALIWEB. Meta tags provide a guide to each page's content. Using metadata to index pages was found to be less than reliable, however, because the webmaster's choice of keywords in the meta tag could potentially be an inaccurate representation of the site's actual content. Inaccurate, incomplete, and inconsistent data in meta tags could and did cause pages to rank for irrelevant searches.[dubious – discuss] Web content providers also manipulated some attributes within the HTML source of a page in an attempt to rank well in search engines. By 1997, search engine designers recognized that webmasters were making efforts to rank well in their search engine, and that some webmasters were even manipulating their rankings in search results by stuffing pages with excessive or irrelevant keywords. Early search engines, such as Altavista and Infoseek, adjusted their algorithms to prevent webmasters from manipulating rankings.
The stats tell the truth: the top ad spot gets about 2% of clicks (CTR) on average, whereas the top organic spot gets about 20 times that, 40%. Why? Because people trust it more. They trust the Google brand to deliver the most relevant results to their search query. Anyone paying for an ad might be perceived as just trying to hijack that process for a quick buck. It generally takes 3 months to earn the top organic spot with Google (there are exceptions to this), whereas it takes around 3 minutes to place an ad to get the top spot. Society values those who have earned their way to the top in any field, rather than bought their way.
At our agency, we work with sites of varying sizes, from very large to quite small, and recently, we have noticed a trend at the enterprise level. These sites aren’t relying as much on Google for traffic any more. Not only are they not relying on Google traffic, but also, the sites are getting less than 10 percent (or slightly more) of their organic traffic from the search giant.
