Any SEO specialist or even beginner will tell you that backlinks are one of the most important things for a high ranking web page, and it true. However, there is a lot more to it than just gathering up a vast number of backlinks.
Backlinks are the like recommendations amongst the internet websites, the more number of recommendations you have the greater will be your popularity, a.k.a. rankings. Furthermore, there are two key aspects of getting backlinks that you must always keep in mind, which are Quality back links and Quantity of the backlinks.
Quantity of the backlinks refer to the number of backlinks that your website or webpage gets from different website on the internet. The greater the number of backlinks the great is the chances of ranking higher on the Google SERPs.
However, gathering up backlinks from poorly ranked websites other sources might come with a drawback as well. Having a large number of backlinks from poorly ranked websites with low DA can increase your spam score and might even decrease your ranking.
The other parameter related to getting backlinks is Quality. A quality backlink refers to a link which leads to your website or webpage, from a highly ranked website with a high DA. A single backlink from a high authority domain can help your webpage a lot more than numerous other backlinks from poorly ranked websites.
Think of it like a recommendation for a job, lets you, you want a job at your friend's firm, now if your friend works in the cafeteria at that firm then him giving your recommendation might not mean much to the employers, however, if your friend works in the management position or a supervisor, then him putting in a good word might go a long way for you. Similarly, a backlink from a high DA website, will help you rank higher on SERPs.
Therefore, while planning your next digital marketing strategy, you need to keep these points in mind and aim for getting a backlink form website having DA of 70 or higher. Always check the quality and DA of the website form where you're getting backlinks.
However, getting a backlink from a DA website may not come as easy. Since the website having a high DA has more value for the backlinks they give out, the competition becomes that much tougher. The success will be quite slow, but as you move up and keep building good quality backlinks you will get the hang of what more high ranking website need and how to approach them.
To help you get started, here is a list of some websites with high DA that you can approach for getting backlinks. Each backlink from a website in this link will help greatly in increasing the SERP ranking of your webpage.
