## Google Algorithms & Ranking

More than 90% of all search queries in the world are handled by Google. That’s why, when talking about SEO, we focus on optimizing and performance for Google since you will be reaching more people in it.

### Ranking Process

Here is the broken-down process:

- Crawling: the search engine uses “spider crawlers”, a bot, to scour the web for new or updated content.
- Indexing: when the content is found, the spider crawlers add a copy of the new information into the search engine’s database.
- Ranking: the index is fed through the algorithm to match the best set of data within their database with the search query made by the user.
- Result: the data set is presented to the user in the form of a search engine results page.
