Anchor text is a word that looks at a link. If we want to get good rankings in the SERP for specific keywords, you should use that keyword as anchor text of our blog, but the anchor text should have relevance to the content of our blog. If it does not want to target a specific keyword, use the title of the blog also.
Mistake 5: exchange links with Just Blog That Has High Pagerank
