Hello friends,

How Long Does A Back Link Exist For SEO..?

Not sure about your question, but a backlink value stays forever unless it is broken or removed by the webmaster.

Hi Friend,
In one Moz case study, a small sample size of 76 links was analyzed to determine how long before a new link can trigger changes in Google rankings. The results indicate that a single backlink takes an average of 10 weeks to push a page a rank higher on Google.

There's one caveat though: Building 500 or more links in the first 30 days can temporarily reduce the rankings of a brand new site. However, as long as the backlinks are natural and came from high-quality and relevant sites, the page will eventually move up to higher spots after three months or so.
