Internal backlinks
Competitors are a fact of every website and service. When you create your content, it is important to review them. It is important not to copy other people's content. You want to produce better content than your competitors.
(Longer content, like I mentioned before, tends to get more backlinks, share... and better rankings in Google.
First, identify high-quality, relevant links.
You can also tell Google that you are active on these social media sites and you produce regular content on your website. This is a win-win for your SEO strategy.
