No one should consider guest posting as a simple method that will help you get lots of links quickly and easily. It can take a long time to approve content, as all the related questions are usually discussed via email.
Posting costs vary depending on many factors, but website age, audience size, and link metrics impact the most. A link can be an excellent addition to a donor’s site if they are okay with these three points and if the subject lines match.
Sometimes, webmasters forget about relevance and focus only on domain authority, page score, and other domain indicators. Using this tactic increases search engine algorithms’ attention, and can lead to bad results.
It is better not to give Google any additional reason to doubt the nature of links. If you choose relevant donors, you can get something more valuable along with backlinks — targeted visitors, some of whom may eventually join your regular audience.
