Have you ever held a magnifying glass to your computer monitor and counted the pixels one by one? That’s the level of detail revealed about your website by search engine crawlers: every word, title, image, meta tag and load time for every page. They know more about your site than you do. What crawlers learn feeds search engine algorithms that determine how your site ranks in search results, affecting clicks, conversions, shopping cart size and brand loyalty. That’s a lot of power.
