This spam flag often coincides with a larger number of external links.
A standard feature of a high-quality website is one with a healthy number of internal links pointing to its own pages.
Websites that do not have this feature have a high probability of being spam.
10. Page with lots of anchor text
Websites with an unusually high proportion of pages with a lot of anchor text compared to detailed, high-quality content are a strong indicator of spam.
Once again, directories of low-quality blogs are a good example of this type of spam.
11. External links in the navigation
These are websites that have a significant number of external links within their website navigation structure (think sidebars and footers ).
Websites that use this practice are almost always spam.
12. No contact information
Reputable sites will have the option to contact you on their website.
This is typically a page dedicated to contact information or, at the very least, a section in the footer or sidebar of the website that displays contact information.
Websites that do not have a contact option are considered spammy in Google’s eyes.
13. Low number of pages found
14. TLD in connection with spam domains
These are websites that originate from top-level domains (TLDs) that are known to produce spam websites.
Websites originating from the TLD “.loan” are an example of this type of practice.
What else you should consider
Now it is important to remember that the spam score is not always enough to make a decision.
Sometimes it is quite easy to decide whether a backlink is spam or not based on the spam score alone.
But sometimes it can be a little more difficult.
For example, most higher Yellow Spam scores (6-7) and lower Red Spam scores (8-10) require further research to make an informed decision about the spaminess of the link.
In such situations, you can use a combination of the other columns in the Backlinks module and the web page itself to come to a more informed conclusion.
Here are some important indicators to look out for:
Thin content
Google doesn’t trust thin content (content that has no substance or adds no value).
