It is probably the easiest to write finance guest posting for a blog for which you have already written posts for. But the challenge is to pitch to a new blog to publish your work. According to the SEO experts, the second link from the same website has less leverage than the one from the referring domain. Hence, always build links from the new referring domains.
In this way, you can also explore many opportunities to get new links from the new referring domains. Also keep in mind that Google’s PageRank has a look at the backlinks between the pages and not websites. So if you become a regular guest poster to a famous blog, be our guest! Ensure that you don’t link the same pages on your site from every new guest article.
