Linking can be a great way to build your organic on-site SEO, but you can’t include just any link on your homepage, or any page, for that matter, including blogs.
The first thing you’ll need to understand is that links from popular pages rank higher. This is a basic principle of link-building that focuses mainly on domain authority. Basically, the more links a page has pointed to it, the more authority it has. Each site has a domain authority score that’s based on a scale of 1 to 100, with 100 being the greatest. This is crucial to understand when it comes to intelligently choosing which links to include in your own blogs. There are tools you can use to search for these premium sites, like Moz’s free domain analysis tool.
Forming A Link-Building Strategy
It also helps to understand how to use popular, authoritative links when it comes to building a link-sharing strategy. We only implement a link-sharing practice if it’s useful to readers, like to help local businesses and local buyers find local relevant resources. It is not recommended to have a link-sharing scheme to manipulate rankings.
You want to connect with popular sites, or maybe even sites within your industry (though probably not your competitors) so you can establish credibility. Who are you going to target to get them to link back to you?
