In fact, Google Suggest is the best way to find good long tail keywords that people use to find information on Google. Google admits that while Google Autocomplete (another name for the Google Suggest feature) was not designed specifically for marketing, it can deliver meaningful insights and help stay on top of trends. There are also many clever ways to use Google Autocomplete that can help you with SEO.
I just downloaded a free version of LTP 3.1.0 and I cannot figure out why I can’t see the table headers of ‘Page Authority’, ‘Domain Authority’, ‘Juice Links’, etc next to ‘Keyword Competitiveness’. Normally, I should be able to see these but instead I see new categories like ‘Trust Flow’, ‘Citation Flow’, ‘Domain CF’, ‘Domain TF’ and so on. I thought I can still use the regular version of LTP for 10 day trial so I am not sure why I see different categories. Is it b/c I am on version 3.1.0 instead of 3.0? Let me know if you have any idea.Thanks!
While this one isn’t necessarily a keyword research tool, it will give you valuable insight into how the keywords you’ve been optimizing for so far are actually performing for you. You might realize that you could start ranking for more keywords with more difficult competition, for example, or that only keywords on certain subjects are working for you.
In addition, you can dig into the paid side of search and find out what keywords your competitors are bidding on, and then leverage those keywords for your own organic benefit if you're not already doing so. Search Metrics does this as well, but I've found SEMRush to provide a greater range of keywords and they save more historical keyword data than Search Metrics.
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.
