Website Weight

The more people link your website to their content, the more Google will recognize your website’s content as having higher quality and credibility, which in turn will increase your website’s weight and improve your SEO ranking.

Website relevancy

Google will not only detect the number of backlinks, but also the source of the backlinks and the relevance of the website itself, which will also affect the quality of the backlinks. If the backlinks of the beauty product pages are all from basketball blogs, they will be easily identified by Google as having too low relevance, lacking credibility, and suspected of black hat SEO. Therefore, a large number of methods of creating links in content farms or spam websites cannot increase the weight of the website even if the number of links is large.

Backlink quality

 The quality of backlinks is also the basis for determining the weight of websites, and 4 main factors affect the quality of backlinks:

  •  Link depth: The higher the level of the website, the better the quality of the links. For example, the depth of links between the homepage and Footer is better. 
  •  Website weight of the source link: For example, if the backlinks to beauty product pages come from well-known beauty websites, the quality will be better than that of ordinary blogs. 
  •  Description of anchor text: When setting up a link, the description of the anchor text is best related to the content of the linked website. If the content of the webpage is mainly about the comparison of gym fees, setting the anchor text to “Gym Fees” will be better than “Gym” and “Gym Recommendation”. 
  •  Link creation time: The shorter the link creation time, the better the quality of the link. Therefore, if you want to maintain stable results, you must update the link frequently.
