Google Algorithms
With more than 2 billion websites in the world and 2 trillion searches a year, Google has its work cut out for them when it comes to connecting users to the information they need. How does it manage all of that? With a complex set of algorithms, of course.
Here's what you need to know about Google's search algorithms and how they impact SEO.
What are Google Algorithms?
Google’s algorithms are a complex system used to retrieve data from its search index and instantly deliver the best possible results for a query. The search engine uses a combination of algorithms and numerous ranking factors to deliver webpages ranked by relevance on its search engine results pages (SERPs).
How do search engines work?
Search engines work through three primary functions:
Crawling: Scour the Internet for content, looking over the code/content for each URL they find.
Indexing: Store and organize the content found during the crawling process. Once a page is in the index, it’s in the running to be displayed as a result to relevant queries.
Ranking: Provide the pieces of content that will best answer a searcher's query, which means that results are ordered by most relevant to least relevant.

Here is a list of the major Google algorithm updates over the past 10 years and a short summary of what each meant to webmasters and users.
Algorithm updates
In general, we can divide Google algorithm updates into two categories:
●Minor updates
●Core updates
Google tweaks its algorithm quite often.
And by quite often we mean several times a day. Most of these changes are very small and people don’t notice them.
Besides these small updates, Google rolls on new updates in the algorithms every 500 to 600 times year. These usually create a lot of buzz in the SEO community and often get catchy names.
