Quality of linking root domains. Here is where we get to the quality of each site’s LRDs. Using the same LRD data you exported from either Moz’s OSE or Ahrefs, you can bucket each brand’s LRDs by domain authority and count the total LRDs by DA. Log these into this third sheet, and you’ll have a graph that illustrates their overall LRD quality (and will help you grade each domain).
No, but you will need to have completed keyword research beforehand - and I mean thorough keyword research, not a bullshit download from Google Keyword Planner. You will need to have a handle on the competitive metrics for your target SERP's. If you have no idea how to get these, I strongly encourage you to also check out my course Master Keyword Research.
This section serves as a summary and analysis for all of the research you've done so far. You'll review all the aspects of your competition's business and determine whether they are strengths or weaknesses. List their strengths and advantages under "Strengths" in the worksheet. Note down how equipped you are to deal with these strengths. Can you do better than them or would it serve you better to outdo them elsewhere?

Now the ad servers don’t create this table themselves, they license it from another ‎company like MaxMind or DigitalEnvoy, whose primary business is geolocation ‎data.   This is no enviable task; IP addresses themselves don’t necessarily have an ‎obvious pattern in the way they are assigned like a telephone area code would.  It’s ‎a bit like solving a mystery, and the geolocation companies use a variety of ‎methods to approach the problem.  ‎ /injects>
