Ryan’s Take 
If you want your blog to be discovered and make some money from it, keyword research is a must. Of course, I favor SE Ranking’s keyword research tool. It’s wide range of options, accurate tracking, and affordability make it a great option for finding and monitoring hot keywords in any particular industry. The article does mention two very popular tools – SEMRush and Ahrefs. I’ve also used both of them on a limited basis. They’re also excellent for keyword research but tend to be more on the pricier side.
Google Analytics and Google Webmaster tools are both free and will give insight into popular keywords that are linked to your website for search queries. Google’s Search Console, a toolset within Webmaster Tools, integrates nicely with SE Ranking. You’ll be able to identify and track keyword impressions and positions for certain terms you might’ve not been aware of. Impressions are very important, but clicks are the most important aspect of keyword research.
Clicks tell you which terms convert the best for search queries. You may have a 1000 impressions for a term with no clicks. This typically means it is a good candidate to track and target that keyword. On the other side of the scale, it isn’t unusual to have a term get 10 impressions with 5 clicks. The most likely scenario, in this case, are visitors who are specifically looking for your brand or product. So if your business is named “Best Guys Plumbing”, you can assume that people are actively trying to find your business if the impression to click ratio is high.
The important thing to remember with targeting and researching keywords is that you need to be patient. It takes time and effort to effectively move targeted keywords up in the search engines. Backlinks, optimization and other factors have to be implemented in a consistent manner. It’s hard work, but the pay off will be huge if you can keep it up.
