I hope it’s easy enough for you to clearly see how pretty much any website page or blog post can be slightly modified in order to get optimized around a certain keyword. For the Busy Budgeter example – Rosemarie could easily write a brand new article – or change the title of an existing article that is already written on a similar topic, add some subheadings and a few paragraphs and have it optimized for this really low competition keyword. A keyword like this will likely bring in new visitors month after month – and Rosemarie could direct readers of that article to some of her ‘make money online’ tutorials that we already know are very profitable for her!
Answer: Google Keyword Planner was created to find keywords for Google ads. It will likely not produce very good keyword suggestions for SEO or content marketing purposes. Google Keyword Planner often hides good long tail keywords. To find long tail keywords for SEO, you can use Keyword Planner alternatives such as Google Trends, Google Suggest or Keyword Tool.
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.
