The Signals of Spam Score

1.      Low MozTrust to MozRank Score

 MozTrust and MozRank scores are the two important metrics used by Moz to determine the credibility of a website. If a website has a low MozTrust score in comparison to its MozRank score, there is a high chance of it being spammy. 


2.      Large Site with few links

 If a site has many pages, but few links, it means that the content on the website is not useful. Therefore, these pages are not worth linking and thus considered spam.


3.      Ratio of do-follow vs no-follow links

 The ratio between dofollow vs nofollow links is important. If inbound do-follow links of a site are higher than no-follow links, then the site may not be earning those links naturally.


4. Minimally branded anchor texts in inbound links

 Using specific keywords as anchor texts will not be helpful for your page ranking. There should be a balanced ratio of different types of anchor texts to ensure that the links are optimized well. 


5.      Thin content

7.      Low number of internal links

 Internal links help users stay longer on a website, giving them a meaningful experience. Less internal links may be marked as spam.


8.      No contact information

 Well-established sites always have contact information. This helps the user correspond with the administrator.


9.      Low number of pages

 Websites with few pages are considered spam. That does not mean you have to create hundreds of pages. Rather meaningful and valuable content is important.
