The best links to your website are the ones coming from real websites, with good content and lots of social media shares.
You can either earn these backlinks, or build them yourself. As long as they come from the authority websites in your niche, they have great SEO value. I will not insist to talk about a specific link building method, because what works for me, might not work for you. This is the reason, why, at the beginning of the article I said you should do your own tests and decide what’s best for your website.
You can also check what your competitors are doing in terms of SEO, and if their strategy works, try to build the same links.
The most common methods to build quality backlinks are:
Guest posts on related websites
Broken links method
Email outreach to influentials
