Can anyone please advise me? I have been selling guest posts and sponsored posts on my website which includes do follow backlinks, but now I have had feedback from a customer that the links have "rel=noopener" in the htm...
Does adding rel="next" and rel="prev" in the links for pagination help SEO or rank? An example would be: <a href='page/1' rel='prev'>1</a><a href='page/3' rel='canonical '>2</a><a href='page/3...
What is the rel=canonical tag and why should I only have one per page?
