Backlinks will remain a vital Google ranking factor. But, effective link building is now about trust and pop ularity. Only high-quality backlink works in this model. According to Copyblogger Famous SEO Magazine domain trust/authority represents 23.87% of Google’s ranking alg orithm.
Domain Authority (DA): It’s important to know the domain authority of the sites that you consider for link acquisition. A great tool for this is the Moz Bar, which shows the authority status of any domain or keyword in the search results. Domain Authority was specially designed to determine the quality of links pointing to a site. It ranges from 0 to 100. The higher the number, the better.
If most of your backlinks come from sites with high DA metrics, your SEO rankings will improve, you will have a high PR, and link acquisition will become easier
