What are Google algorithms for SEO?

Google algorithms are the set of rules, detections created to analyze and rank websites leading to manipulation of traffic.
There is a various algorithm like Google penguin which checks low-quality links to a site and decrease the ranking.
Each year there are many new algorithms like this, each algorithm designed to do a different thing like
- one to catch low-quality spammy links
- one to detect stuffed links
- one to check duplicate links
like the algorithm is a little complicated and does more than this example. With each algorithm update, there may be a boost to site rankings, or a drop to site rankings.
it takes around a week to a month to get stable results after an algorithm update.
