No one wants an email inbox full of spam, so spam filters are extremely useful. Google Search faces a similar challenge because the Internet contains a lot of spam that, if not dealt with, won't be able to display the most helpful and relevant results. Google uses a range of spam detection systems, including SpamBrain, to address content and behavior that violates its spam policies. These systems are constantly updated to stay on top of how spam threats are evolving.
Deprecated systems
The systems described below are provided primarily for historical reference malta whatsapp lead purposes. They have been incorporated into successor systems or are already part of Google's core ranking system.
Hummingbird System
This was a major revamp to Google’s overall ranking system that it introduced in August 2013. Since then, Google’s ranking systems have continued to evolve, just as they have always evolved before.
Mobile-Friendly Ranking System
If there are multiple possible matches of relatively equal relevance, the mobile-friendly ranking system prioritizes content that renders better on mobile devices, which are more useful to users searching on those devices. This system has subsequently been integrated into Google's Page Experience system.
