KWFinder was developed and created by Peter Hrbacik. He is amazing at providing great support for the tool. They have live chat on their website, which I have used quite a few times during the day. Also, their email support is also awesome. Below are a couple email conversations I have had with Peter. In this first email I suggested that they make the category headers clickable. Peter responded within 24 hours and said they will probably change it. And a couple days later, the change was implemented.
2) SpyFu: I suggest to have paid account on SpyFu. I just need to find my competitors who using Adwords and review them using this tool. It will show me what ads and keywords they are using. Note that my competitor who paid for that particular keyword knows exactly that it is important for his business including recent trends. Also using SEO feature you can input any URL and find our which keywords they are ranking for.
They also seem to be getting this wrong often enough that I've got less confidence that the keywords that make up these groups really belong there. I recently tried to check the volume for the keyword [active monitoring] (the practice of checking on a network by injecting test traffic and seeing how it's handled, as opposed to passive monitoring) and the Keyword Planner gave me the volume for [activity monitor] (aka Fitbit).
Here is the annual pricing for KWFinder. I use the tool so much that I always go for the yearly pricing because of how much you can save (44% to be exact!). If you look at the alternatives, SEMrush cheapest plan is $69.95 a month and cheapest price with search volume is $88 a month. So really, KWFinder is a pretty good deal when it comes to pricing! The basic plan gives you 100 searches per 24 hours, which is plenty for most people.
You can also block certain files or folders with passwords to the public or from certain bots. For example if you are still setting up a site and don't want it accessed - you can block it. This is very useful when building your Private Blog Network, because you can block tools like Ahrefs and Majestic from crawling your PBN site and hence hide any backlinks to your main money site from being discovered by your competitors (and therefore hide your PBN entirely). You can read up on Private Blog Networks and how to build them in my PBN guide.
It's wonderful to deal with keywords that have 50,000 searches a month, or even 5,000 searches a month, but in reality, these popular search terms only make up a fraction of all searches performed on the web. In fact, keywords with very high search volumes may even indicate ambiguous intent, which, if you target these terms, it could put you at risk for drawing visitors to your site whose goals don't match the content your page provides.

Hey, friends! Today I’m going to share some ridiculously easy (and free!) keyword research tips to help your blog posts get more traffic. We’re going to keep this easy-to-read without getting into all that confusing keyword mumbo-jumbo. Plus, this method doesn’t take more than a search bar! Easy, right? If you’re new to keyword research, then you’re in the right spot!

Some of the keyword research tips we’ll cover might not look like they’ll do much for your organic SEO. But just because your audience isn’t Googling the topic doesn’t mean they won’t find it useful. Organic search metrics aren’t everything. Traffic is traffic. So some of these techniques are aimed at helping you research for content that will invite shares or be perfect for running ads to.
Note! Google often shows search results for general meanings, rather than specific words and phrases. When you search for a phrase in Google, you’ll see the keyword bolded in the search results. Look closely and you may find words you didn’t search for bolded in those same search results. For example, a search for “HVAC repair” returns search listings with phrases such as “heating” and “air conditioning.”
