How Does Google Know What Ads Interest My Audience?
From the day you start offering ads, the AdSense robot visits on a regular basis, reading through your pages with ads. The robot takes a look at the words you use, the frequency with which you use them, even some of your page structure and formatting (for example, bigger fonts usually signify something important). Then Google uses all this info to figure out which ads your readers will warm to. Even better, Google takes the language of your site and the location of your visitors into account, serving up language- specific, location-targeted ads for maximum impact. Another factor in the determination of ad media for display on any AdSense-enabled site is the user’s browsing and search history, tracked through cookies. Google goes beyond simple keyword matching to understand the context and content of web pages. Based on a sophisticated algorithm that includes such factors as keyword analysis, word frequency, font size, and the overall link structure of the web, they know what a page is about, and can precisely match Google ads to each page.Google Tools, Online Marketing, Online Tools, Web Analytics
