Hi – I’ve read your post with great interest. Not only am I happy for you and your success, it does provide a glimmer of hope to those of us who do have “other” ideas. I, too, have had an idea for a very long time now, but I have no idea how to go about “making it a reality.” I am not a programmer either… though I do know some html… I also remember the old days of having even a web developer holding domains hostage, never mind the site’s entire code. And, yes, that is one of the major things that stops me from even discussing things with a developer. I simply don’t trust them…
You can also filter by query, which is useful when looking at branded queries, or when looking at specific words. For example, only show keywords that include the term "SEO". The graph also allows you to spot trends in across the available metrics and compare week-on-week or month-on-month. This can help you to drill down and monitor progression over time, allowing you to answer questions like "have my branded keywords received more clicks in the last month compared to the previous month?", "has the CTR improved?", "did average positions in Google improve?".

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.
As a new customer trying to evaluate the software, I asked if my trial period could be extended once this fundamental issue was fixed, on the basis I couldn’t actually evaluate its requirements against my criteria. I was told this was not possible, which frankly, is very poor customer service. What’s the point of offering a trial period when customers are unable to fully test the software?
Just came on this program this morning and downloaded a trial version. Could this program really be only $97? Is this portion of the program effective or do you need the $300-plus Platinum version? The KC score, available in the $300-plus version, seems critical to making the whole thing work really well. Are you possibly leaving money and success on the table by not biting the bullet and going for the expensive program?
Long Tail Pro is a keyword research tool that helps you quickly find low competition keywords for your website.  In particular, the tool is built for people doing SEO (search engine optimization) as opposed to people doing paid ads (Google Adwords PPC).  I'm sure there are some advertisers that use the tool for paid ad keyword research, but the tool was built for SEO keyword research.
