External link building is a very important link in SEO. When everyone's on-site optimization is about the same, the competition is who has higher quality and more external links. Compared with the quality of external links and the quantity of external links, the quality of external links is more important. One high-quality external link is often better than dozens, hundreds or even thousands of low-quality external links. So what kind of external links are high-quality external links? Below, SEO researcher and practitioner Xie Laien analyzes the two major factors of high-quality external links:
1. External links from high-authority pages
·External links from top-level domain pages
·From pages with high PR value
·External links from domain name pages with gov and edu as suffixes
·External links from famous categories, such as DMOZ, Yahoo categories, etc.
·External links are located in the upper and left areas of the page
·One-way external links
·The external link exists for more than 3 months
·External links from pages with less than 100 export links
2. External links from highly relevant pages
·External link anchor text appears in the title of the external link page
·External link anchor text appears in the meta of the external link page
·The same text as the anchor text appears around the external link
·Text similar to the anchor text appears around the external link (based on search engine semantic analysis)
·The site theme of the external link is similar to the optimized site theme
High weight and high relevance are two criteria for evaluating high-quality external links. The higher the weight and relevance of the external link page, the higher the quality of the external link. It can be represented by the formula:
High-quality external links = external links from high-weighted pages + external links from highly relevant pages
