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.
1) Ahrefs to quickly see “the big picture” when it comes to any keyword I'm researching. I can instantly see the top holders in the SERPs. I then immediately take the top holders list and go check out their sites. I need to make sure I can beat them content-wise, otherwise I will search for another keyword to try and rank for, or perhaps go down the long-tail route. The Ahrefs tool and data quality get better and better every year. It's one of my favorite tools.
I’ve found google trends to be an interesting way to see if a keyword (and by extension a niche) is growing or shrinking, and whether it’s seasonal or not. I can’t think of any other tool out there that can reliably tell you this information, so that’s really useful. Also, if you’re building a site, especially an authority site, getting onto something that’s trending upwards is a fantastic idea.
The pages on your site that are long form content or are the key pages - must have Outbound Links to other "authority Sites" and pages in your industry or niche. By no means should you link to your competitors pages - but Google is rewarding pages that understand which other authority pages exist in its niche - and pull them into a "link cluster". back in the days we were all scared to link out to ther sites - fearing that our link juice will leak out. However, this is not the case and Google is rewarding people for sharing other authority and relevant content online.
We need a metric to compare our specific level of authority (and likelihood of ranking) to other websites. Google’s own metric is called PageRank, named after Google founder Larry Page. Way back in the day, you could look up the PageRank for any website. It was shown on a scale of one-to-ten right there in a Google toolbar that many of us added to our browsers.
As for duplicate content, Google gets confused when you create and publish articles with similar content, and this eventually leads to indexation issues. Keyword cannibalization happens when the owner focuses his effort on ranking for a particular keyword from several different pages. When this happens, Google won’t acknowledge multiple pages; they’ll only focus on the best one thus making the other ones useless and inaccessible to search engines.
1. AdWords Keyword Planner - It's still the standard, although Google keeps making changes that just aren't helpful. I get that they want us to treat closely-related keywords in such a way that we're not creating multiple pages when we should just have one, but I'd appreciate it if they'd still break down the volume for each keyword that makes up a group (or at least list the keywords they're clumping together into a group).
Of all the tools listed in this article, Moz Link explorer is an old one & quite popular. If you want to compare backlinks between two or more domains, Open Site Explorer is worth trying. This tool works best when you have a paid account of SEOMOZ though a free version of this tool is good enough to get you started checking the backlinks of your site and the sites of your competitors.
