There’s a saying that goes, “if Google can’t find you, then your customers can’t find you” and it’s very true. Google finds your site through a process called indexing. The simplified version is this: Google sends smart cyber-spiders out to crawl all over the web and these spiders bring back news of all the new sites and site changes. Google updates its database to include all these news bits and voila, you’re indexed. Now, when Hubert searches Google for neon-green, 80′s rapper pants, he’ll find them at your Ultimate 80′s online store.
That’s the perfect world. In the real world, some sites, blogs in particular, get indexed faster than other sites. Some sites get indexed late or badly due to issues with keywords or graphics that block the text. (Here’s a tip: Google can’t read a graphic, so make sure the name of your site is in the text or meta text.)
