Google has what they call Spiders that crawl the web.
The Spiders are automated bot software that search or crawl the web cataloging all the web pages of the internet.
That’s a lot of freaking webpages. Billions…Trillions.
We type or say a few related words about what we’re trying to find right? Those words are what we call Keywords.
Google then displays what it thinks are the best results base on the keywords given.
Wait, there’s more. It’s not just about keywords that determine search rankings.
If you make sure your website passes what we discussed here, then you are on the right track.
Hope this helped explain some of the basics a gives you at least a better understanding of SEO.
