Ques 25. Distinguish between a dofollow link and a nofollow link.

All hyperlinks are dofollow links by default unless specified as nofollow links. When search engine crawlers find a link, they crawl the page and pass the link juice as a vote of quality. The dofollow links from high-authority sites will help a site rank better in SERP by being quality backlinks.

Nofollow links are coded in a way that search engines do not crawl them or count them as votes of quality. You can use this when you want to link third-party sites on your website without passing the authority to those sites.
