When you get a link back to your site you want it to be a link from at least an equally valued site, and preferably from an authority or high ranked site in your niche. Also, it’s much better if the link to your site is one way. That is, you are not linking to that site. If the search engines think you’re up to some rank back patting with other sites, you could lose out completely.
However, you do want clear internal links between posts and pages in your own site. WordPress themes will link back and forward between posts, though usually in a limited way. Nevertheless you don’t want too much internal linking going on. The search engine crawlers find it confusing if there is too much. Ensure there’s a link back to your home page from each page. If you use a silo organization then only have links between pages within a silo (where pages are on the same topic or category). This makes it much easier for search engines to crawl your site when there is a clear organization.
For building links yourself, content marketing means you can add links into the content and at the end. You get a unique backlink to your site. The more content you create and publish, the more links you get.
The ideal is having a site link to you without being asked for. The more of these you have, the more the search engines will see your site as an authority one in your niche. They will see this as being helpful to customers.and visitors.
Work out a link method and build on it as time goes on.
