Off-page SEO is more commonly known as building backlinks for a website. This is one of Google’s core ranking factors and the quality and quantity of your site’s backlinks will determine where it ranks in Google’s SERPs. A backlink is basically when another site links back to your site; either the home page or any other page of your site. This actually passes what was originally known as link juice which actually powers up your site over time. However, the power that is passed depends on how relevant the linking site is to your website. For example, if you have a website about dogs and another site about cars links to your site, it won’t be a very powerful link because of the lack of relevance. However, if another site about dogs links to your dog site, then this is highly relevant and the backlink would be much more powerful and boost your rankings more than the site about cars.
In off-page SEO, there are many types of backlinks and it is important that you diversify the types of backlinks that you have as well as the anchor texts of each backlink. If you don’t diversify your backlinks, this will look unnatural to the search engines which will eventually result in a link-based penalty. You can choose to build white hat links, black hat links or grey hat links. The safest type of links to get that have the least possibility of getting your website penalized is white hat links. These links are mainly outreach links such as guest posts, resource page links, infographic links, etc. Black hat links are more likely to get your site penalized, but they do tend to work faster for ranking your site. PBN links are black hat links and PBNs are basically websites that you build to link back to your main site(s). Link insertions or niche edits are grey hat links as they do pose a higher chance of getting your site penalized but not as high as PBNs.
In closing, we have just covered the main points about off-page SEO or building backlinks. This is just one aspect of SEO but it is extremely important if you want to get your site ranked as quickly as possible.
