Differentiate between No-follow and Do-follow links in SEO.
The only technical difference between the two is that a nofollow link has a nofollow tag. As a user, it’s impossible to tell the difference between a nofollow and dofollow link. You can click on, copy and use a nofollow link like any other link on the web. … Dofollow links help your search engine rankings.
All links are dofollow links unless they are modified to be nofollow links manually or are automatically changed by a website setting. Search engines crawlers follow dofollow links. In contrast, nofollow links have a bit of code that ask search engines to not crawl them or count them as votes of quality.
