Search engines will appreciate links if they are relevant, high quality and come from a trusted source. A link from SingleGrain.com gets a lot more SEO value than a link from my friend Joe's marketing blog . This is mainly determined by two factors. 1) PageRank reference – both the PageRank of the website as a whole and the PageRank of the individual page hosting the link 2) Relevance – Google will weigh it more if the content linking to you is related to similar keywords (they will look at the keywords that specifically surround your link and determine the relevance of pages covering relevant topics)
No one knows whatsapp database the exact algorithms used by certain search engines like Bing and Google ( that's their secret sauce, after all ). But we know from the occasional press release and testing that these two factors are very important. This is sometimes called "PassingPageRank". This is because when a site links to you, it uses PageRank to vouch for you and give you a score. In fact, the third factor that determines how much PageRank is passed on to your site is the number of outbound links on the referring page. If you have dozens of links in your article, each one will give you much less boost than if you only had 2 or 3.
There's not a lot of PageRank magic to evade, and the more outbound links you have, the less each one can receive. You probably already have a good idea of what sites are authoritative in your industry and niche: sites that everyone reads, sites that have great long-form content, consistently on the first page of Google Sites that are ranked. However, if you want to learn more about how Google determines link value, check out this overview by NeilPatel and Brian Dean . One final thing to note is that you need to make sure your backlinks are not "nofollow" links. By default, search engines use every link they find to determine the value of your content.
