Low Domain Authority - How to determine what backlinks you should keep
There are a lot of factors when it comes to figuring out how much positive authority a website haves and if it is worth the trouble to get backlinks from the specific domain.
Worst yet, you may already be been having backlinks from certain websites that are deemed low quality in Google's algorithm and are actually dragging you down with them.
So how can you figure out if a backlink from a certain page or domain is good or bad for you?
Well, there are a lot of tools out there that can tell you the spam score a certain page haves by checking out their backlinks profile with the help of some algorithm.
1.The Open SIte Explorer from Moz - OSE is good at picking up spammy backlinks and letting your know the spam score.
This is the tool: https://moz.com/researchtools/ose/
If I stumble upon anything that haves a higher spam score than 5/17 I step away from getting a backlink from that domain or if I deal with a website that already haves such a spam score, I find the backlinks that produce the problem and disavow them in Google Search Console.
2.Another tool I use is Ahrefs - Ahrefs is the absolute master on one thing in particular: checking backlinks.
It won't tell you which are rubbishing and need removing but it will show you almost every live backlinks a website haves, including anchor text, actual source and everything in between and you already have more than enough information to implement a manual audit.
Usually, I filter everything by domain, showing just one backlink from every domain, this will filter and hide unnecessary site-wide backlinks, you can usually figure out if the backlinks are worth it just by checking one backlink. If the website I'm analyzing haves less than 200 unique domain backlinks I usually check all of them manually.
If the website I'm doing the backlinks profile analysis haves more than 200 unique domains backlinks I usually implement a few word based filters on the anchor text of each backlinks, spammy words that are usually used in low-quality link building or negative SEO attacks: porn, xxx, viagra, sex and stuff like that. I review each negative results and decide the outcome.
What are the main factors that deem a page or a domain low-quality in Google's eyes:
The content being displayed is not unique;
Too many external pages are linked on that page;
The page doesn't have any real value to users and searches, it doesn't solve any problem;
The page loads very slow giving an overall negative user experience;
The content itself is low quality with grammatical and spelling errors;
The structure of the website is chaotic and hard to understand;
No other high authority external sources link to it
So, these are my main methods and factors I take into consideration when reviewing a page possible authority score. If you have anything to add to all of this please do it in the comments below!
