A link building campaign is a strategy where a business aims to obtain links from other websites to their website. The more links a business has, the more credible they appear to search engines. Link building campaigns are becoming more popular because they are a way to make a website rank higher on search engine results pages. This also helps with other marketing efforts since other sites will want to link to a website with a large number of links. To ensure a link building campaign is successful, a business should have a strong site that will attract links.
