This article will give you some tips and tools to check if you are suffering Google penalties.
Before that, to understand how to avoid Google penalties, you need to understand the “menagerie” of Google algorithms . phone number list
These algorithms are intended to classify sites in order of relevance based on the queries that are made (the “ ranking ”).
At Google, there are mainly 4 star algorithms which intervene in the ranking of sites :
+ PANDA which analyzes and verifies the quality of the content of landing pages and blogs,
+ PENGUIN which analyzes and verifies the quality of the links ( backlinks ) associated with landing pages,
+ HUMMINGBIRD which evaluates the user's intention through the words used for their query – it is also the algorithm that hosts RankBrain, the machine learning system developed by Google,
+ POSSUM which is used to provide geolocalized responses based on the importance or otherwise of geographic data in queries.
The good "ranking" of a site (concretely being "good" means appearing on the first page of Google, or even on the first 3 positions) is the objective of SEO (Search Engine Optimization = optimization of natural referencing).
This positioning results from the “points” accumulated with these algorithms. In general these “points” are “positive”.
