best back links activites

[PMonroe]

Let me tell you what backlinks do for you,
Creating backlinks on good web platform makes your content trustworthy to the search engine ,mainly we crate backlinks to make content to be indexed on search engine as Google ,but only Dofollow website because Nofollow link never get indexed by google it only can give you visitor so without engagement you will get nothing . After indexing more and more links that allows you to be trustworthy to the search engine and makes your rank on the search result.
And the rest has already been discussed and i will repeat with RH-Calvin

Also replacing dead or broken links in Wikipedia is a very good backlinks strategy. But few people use it, because it takes more time that article submission for example.
