What Google revealed in its spam-fighting journey
- Buying or selling links that pass PageRank can dilute the quality of search results. The paid links are considered to be a violation of the Googles Webmaster Guidelines. Google has updated its ranking system. These type of links will be less effective than it used to be.
- The auto-generated and scraped content are the two primary spam trends in 2019— for instance, fake buttons, overwhelming ads, suspicious redirects and malware are the most common forms of said spam. These type of spam typically engage in behaviours that annoy or harm searchers.
- Google values the importance of user feedback. 82% of the reported issues have been handled.
- A manual action notification won't affect your appearance in search result page immediately. Check Webmaster Guidelines for further improvements.
How to avoid spam and optimise trustworthiness on your site
- Google recommended applying new link attributes to differentiate the spammy content on your site. Examples include spammy posts on forum threads, comment spam on blogs and paid links.
"We introduced two new link attributes, rel=" sponsored" and rel= "ugc", that provide webmasters with additional ways to identify to Google Search the nature of particular links. Along with rel= "nofollow", we began treating these as hints for us to incorporate for ranking purposes."
- It's recommended to sign up for Google search console and verify your website. (e.g. Auto-DNS verification in the new Search Console)
- Regularly check the new Search Console messages. Follow the Webmaster Guideline if manual action occurs.
