Ivan from Sersptat here to share with you guys our new ultimate KD tool. Discounts will be given to those of you who also think our tool is cool (cuz we checked and it is 8)) and PM me to say so.
But before I explain how this works, there are two common ways to calculate KD. By analyzing backlinks of top domains and by analyzing backlinks of top URLs.
First Method to Assess KD
Within the first method, KD is an average value of the number of backlinks every domain in top 10 has. The main disadvantage here is that the entire domain is analyzed instead of a specific page. Thus if some not influential and not relevant page of such trustworthy domain as Wikipedia or Amazon, e.x. is in top-10 of Google SERP, the KD for this keyword will increase.
The problem with tools like Moz is that they allow for wide discrepancy assessing the keyword difficulty relying mostly on the number of backlinks. This is exactly what the kind of issues that we had at Serpstat when we first decided to build our own keyword difficulty tool.
Second Method to Assess KD
The second method is based on the number of backlinks every page in top 10 has, where KD is an average value. Sure, backlinks are the crucial ranking factor, but not the only one. That's why this method cannot be considered as a perfect one.
How we calculate KD?
We used the second algorithm as a basis and added several additional metrics to improve its accuracy. Here are all the parameters we consider:
Referring Domains — shows the number of domains that refer to the pages of Google top 10;
Backlinks — the number of backlinks pointing to the pages of Google top 10;
Page Rank refers to the number of backlinks your site got;
erpstat Trust Rank refers to the number of trustworthy and quality backlinks your site got;
omains with the keyword in title — the number of domains that contain the requested keyword in title;
URLs with the keyword in title — the number of pages that contain the requested keyword in title;
pages in SERP — shows how many main pages are in top-10 of SERP.
This allows for a much more accurate data that takes much more relevant ranking factors into account. This makes our KD tool the sharpest on the market given that our US database for
