there is no minimum number of backlinks, it depends on your ability. Google now focuses more on your content.I am an SEO worker. I know all the terms of SEO but I have no idea about the minimum limit of backlink. How many backlinks are essential to promote a website?
That's a very basic way of link building but it still works. It all depends on the type of area your "money site" is trying to compete for.article submission
profile and bussiness listings
This is not always the case it all depends on the campaign for example: I could be building links for a finance company thats got a very competitive market so it will be quality over quantity however, I could have a company that sells pencil sharpeners that has a very low competitive market so it would be quantity (reviews, directories ect...)Quality over quantity. Always. You can have a thousand crappy links and that'll dig your grave in the search engines. But you could have a hundred good links and that'll help your rankings.
