SEMrush is a very useful tool for both researching competitors when starting a site or for growing an established site. I really like to find weaker niche sites that still seem to be ranking for lots of keywords; SEMrush helps me see what they are ranking for and what I can potentially target. You can also see what keywords you’re on the cusp of ranking for with your established site - another very useful feature.
However, KWFinder has a couple of areas where Longtail Pro outshines it. Firstly, I like the fact LTP provides you with a suggested keyword competitiveness to target (as described above). More significantly, I don’t like the way that KWFinder restricts your number of keyword suggestions if you choose their cheaper pricing tier – it feels like they’re holding back some of the power of the software unless you pay more. With LongTailPro, you can see as many keyword suggestions you like so long as you’re within your monthly allowance.
I want to ask that when you were the owner you offered a life time membership option which i think should be offered one last time before migrating to new plan.Long Tail Pro Users who had bought the software @ USD 97 and were paying USD 27 per month on as per need basis have no edge over the new users.As you are still 20 percent owner of the business so it is requested to please give old users who already owned and purchased the basic software one time life time license offer or discounted price.
The Google Keyword Tool has a variety of helpful features meant to streamline the keyword research process. By entering terms or phrases into the search box, the Keyword Tool allows you to build extensive, relevant keyword lists from one simple interface. By default, the tool displays Advertising Competition, Global Monthly Searches, Local Monthly Searches, and Local Search Trends for each keyword. Additional options allow marketers to show the estimated Average Cost per Click, Ad share, and Search Share.
Pricing plans and pricing structures for Long Tail Pro have changed several times over the years since I first purchased it. I’m not going to make the mistake of publishing any pricing information here. I’ve done that in the past on this blog and I still have several old posts that are live with incorrect pricing information. There is a good chance that people will still be reading this very post several years from now – and surely the pricing that is available today will be different in the future. Just like it was way different in the past. Please click on any of my links within this post or anywhere else on my site to see the latest prices for Long Tail Pro.
To answer your final question, yes but not really. You can definitely use AdWord keyword planner tool to get solid organic search volume estimates. However, don’t just stop there. Leverage other tools to find longer tail variations you can map against various stages of the buyer journey. I like to use SEMrush, Keyword and Google autosuggest.
"This is the only keyword research tool that I recommend. The ideas, inspiration, and content longtails you will get for your niche topic are going to result in you producing a page of content that is more than going to pay for this tool. And as they are Google's database then we KNOW that these terms are being searched by a decent volume of peeps every month. It's a goldmine dudes."
4. Set post-search filters. After your keyword suggestion fetch is completed — which might take a while if you input a lot of seed keywords — you need to filter your list. You can: filter out keywords that don’t include buyer modifiers like “best”, “buy”, “purchase”, “discount”, “review” (it’s possible to input one or more words in the filter field at the same time: just separate the words with a comma); add a minimum and maximum amount of LMS; set a minimum amount in “Suggested Bid”; and check for only high “Advertiser Competition” keywords.
"This tool is simply Amazing. I've been uncovering literally thousands of highly related keywords for my clients websites, with this tool new content ideas have become a breeze. I literally have hundreds of new ideas for articles to write about for my sites and my clients sites. The Keyword Researcher tool was truly a great buy for my business and I highly recommend it to anyone."
The limit on manual keywords could be higher.  I personally wish we could input 10,000 keywords at a time, instead of 200.  However, I understand the costs that Long Tail Pro has to maintain each time a new manual keyword is input.  Not a deal breaker, I just wish the limit was higher. (To be fair, I don't think most keyword tools have a bulk manual option at all).
