Because someone who is looking for something that specific is probably a much more qualified searcher for your product or service (presuming you're in the blogging space) than someone looking for something really generic. And because long-tail keywords tend to be more specific, it's usually easier to tell what people who search for those keywords are really looking for. Someone searching for the head term "blogging," on the other hand, could be searching it for a whole host of reasons unrelated to your business.
1) Google Keyword Planner: This tools is fantastic because it can help me to identify long tail keywords for my niche. It is official Google’s tool and it has the recent trends and keyword variations. For example you may think that this keyword is great “buy ipad air in liverpool” but Google may suggest “iPad air sale Liverpool”. Yes, not often it is accurate but when I’m using it alongside the other tools – I can get clear idea.
As for the history of the company, as I explained, I created Long Tail Pro back in 2011. At the time, I was creating tons of niche sites and was doing alot of keyword research and content creation. I was trying to figure out what types of keywords would rank quickly in the search engines, specifically Google, and I was frustrated with the other keyword research tools (in particular Market Samurai) out there.
