Howdy gang,
This is my last discussion post in the series on keyword metrics in KW Explorer & Moz Pro (previously on Keyword Difficulty, Opportunity, & Volume). In this one, let's chat about the "Priority Score," a feature you'll find in Keyword Explorer on any lists you build.
Priority was conceived to help aggregate all the other metrics - Difficulty, Opportunity, Volume, and (if you choose to use it) Importance. We wanted to create an easy way to sort keywords so the cream would rise to the top -- cream in this case being keywords with low difficulty, high opportunity, strong volume, and high importance (again, if you choose to use it). Thus, when it comes to Priority Score, there's no particular number you should necessarily seek out, but higher is better.
When you get into the ranges of 80+ (which is quite rare, Single Malt Scotch is one of the few examples I could find, and only because it's volume is so high and there's only a couple SERP features), you're generally talking about keywords with high demand (lots of monthly searches), the difficulty isn't too crazy (a website in the 55-80 DA range might have a shot), and the CTR Opportunity is decently strong (usually not too many SERP features that take clicks and attention away from the organic web results). Below that score range, you're usually finding keywords where one or more of those isn't true -- there's either lower volume, heavier competition, or lots of SERP features with the accompanying lower estimated CTR.
When you're building KW lists, my view is that there's no "good" or "bad" Priority scores, only relative scores. Priority should be used to help you determine which terms and phrases to target first -- it's like a cheat code to unlock the low hanging fruit. If you build large lists of 50-100 or more keywords, Priority is a powerful and easy way to sort. It becomes even more useful if you use the Importance score to help add an estimation of value to you/your business/your client in to the mix. In that case, Importance can cut Priority by up to 2/3rds (if you set it at 1) or raise it by a little more than 3X (if you set it at 10). This is hyper-useful to nudge keywords with middling scores up if they're super-important to your marketing efforts.
Look forward to your feedback, and thanks for checking these out!
