At first thought, you may think that linking to another website with relevant content wouldn’t be a good idea as these may include competitors. This is not the case. Imagine looking for a local company to help you with your SEO. You proceed to read on their blog about ways you can work on strategies on your own. They provide links to back up their data. These links to larger national sites with great site authority substantiate their claims. And of course, another great reason to link to relevant sites – Google will rank you higher in search results (it’s a part of good SEO practices).
