Ordered the monthly pack to give this a try. After payment was redirected to login form that keeps pushing the 'Authentication failed. Please try again.' message... this is a disappointing start.
Why are some keywords already showing the difficulty score and others I have to pay to check? just searching 1 word would of cost me $17 as there was close to 200 words I needed to check the difficulty of. I just wondered if I was using the tool wrong because having to spend that much money so often doesn't seem realistic I could easily spend hundreds in a day just getting a list of keywords.
Thanks for clearing that up, per day is very reasonable and I have purchased itA few things here. You get 200 credits per day, not per month. So credits reset each day as 12am EST. We have around 100 million keyword keyword difficulty scores in our main database but our keyword database has billions of keywords. Even much more expensive tools like Ahrefs and SEMrush don't have difficulty scores for all of the keywords in their database. To compare to Ahrefs they have 148 million keyword scores in their main database, but they are also 10x the price. A basic plan with them will get you 500 credits per month (not per day) and each time you filter, or sort you use a credit.
Our keyword scores are probably the most accurate in the business as they take many factors into account (incoming domains, links, the type of links ********/nofollow, domain authority plus much more), so they are resource intensive to generate. Unlike Ahrefs which uses literally just 1 metric (incoming domains) to judge difficulty which is pretty inaccurate.
I won't mention names here, but any tool that is showing difficulty for every keyword should not be trusted. It means they are either literally making it up or using a very simple metric like average DA or something that is only marginally better than just guessing.
With that said, if you do a search and there are many keywords you are not seeing difficulty for, you can first use our filter to filter out certain keywords to narrow it down and save credits. For example filter out keywords with search volume under 50 or keywords with 2 or words less. Things like that can help narrow it down.
Hope this helps clear things up!

Hey thanks for the kind words, it's much appreciated! Yes, more mobile friendly is definitely on our radar. Our hope is to do some work on UI updates which would include things like that. Not sure of an ETA yet but it is on the priority list.Use this tool pretty much everyday since it released and just realized I have never made a post about it. Love it! Quick and easy keyword research.
Do you have any plans to to make the website more mobile friendly? I'm probably a small use case but I do a lot of work on the go as ideas pop into my head.
@dp40oz Can you please explain the difference between “Keyword Difficulty Score” and “Rank Strength Score”? Are they basically the same thing? Thanks!
CPC is taken from adwords but won't match exactly. Since CPC changes very often we use more of an average than an exact adwords match. Hope this helps clear things up!Those of you who saw my comments about other services know, i dont go easy on anyone and if they are trash, rest assured i will let you know about it with no mercy to the sellers.
I used this service multiple times before for my websites and i know it is great, because all the keywords i found are ranking good or bad based on the metrics i got from this. So the data is accurate.
I am planning on using this again, but for other reasons.
Question to the seller. This probably has been asked multiple times already and im sorry for asking it again, but CPC provided in the data is based on adwords ? I mean if i were to look for keywords to use with adwords, i could expect to see the same CPC prices running adwords campaigns ?
