Since not all links are equal, you must invest in organic SEO services to ensure your links tick all the boxes in regards to the factors Google utilises to analyse links.
One factor is contextual relevance. The text before and after a link acts as contextual relevance for the link’s destination page, helping the search engine decipher how the link relates to the content it is placed.
Another factor is source relevance. If your post is about vegan recipes, and you link it to a page about criminal law, there should be a good reason for it. You’d rank higher if you linked it to a food website.
The anchor text, the clickable text that houses your link, is also important. Get the balance right by using keywords but you should not go overboard with keyword-rich anchor text.
Hopefully, you now have a better understanding regarding the factors Google use to assess SEO links. An organic SEO expert will consider this to ensure your links are working for your SEO campaign.
