What are strongest backlinks to rank high?

[sonth321]

As title mentioned, I thought it id hard to find strongest backlinks because it is not easy to track which backlink has influenced the SERP rankings the most and the backlinks depend on more factors like site history, backlinks from content, hard backlinks or authority sites...etc

But I am wondering, from your experience where are sources for best backlinks? If you know, please share a bit of your experience and explaining why it worked and why its the best?

You must not think like this.
A backlink must be :
1/ from a good website quality (SEO)
2/ from a good page quality (SEO)
3/ from a similar theme as you're website

Those are the points you must focus on.

Spammy Backlinks are not good.
In fact, that’s how Google is able to spot spammy links. Google can track if users click on a link and evaluate what percentage of people that visit a page actually click on the backlink. The more people that click and stay the better quality the link is. That makes sense right? Conversely, the more people that visit the page and do not click on the link gives a hint to Google that the link is relatively useless. This is proof that Google can identify spammy links and quality links. Think before you link!

Hello, I think that backlinks are very important in rank high! Link building is the process of getting other web pages, and web sites to place a hypertext link to yours, which generates direct targeted traffic to your site, while more importantly increasing your search engine visibility and rankings.

Strongest backlinks can be built with the help of good content. Content is a vital factor for search engine rankings and promoting high quality content in various Web2.0 blogs and submission sites help to build your website ranking faster and higher in search engines.
