So what is SEO?
SEO is short for Search Engine Optimization, and there is nothing really mystical about it. SEO is a measurable, repeatable process that is used to send signals to search engines that your pages are worth showing in Google’s index.
Basically Google uses a complex mathematical formula called an algorithm to give a score to every website and every search people to do in Google to figure out which website should rank best for what people are looking for.
Think of the algorithm like a collection of empty buckets. One bucket gives you a score for the quality of your site, one bucket gives you a score for how many sites link to you, one bucket gives you a score for how people trust you. Your job is to fill up more buckets in the algorithm than any other website.
You can affect your search engine ranking
