20 Free Keyword Research Tools – Comprehensive Insight

title-free-keyword-research-toolsBefore you write any good article or optimize website, you have to know how and why you have to select right keywords. SEO is very easy to overuse and do even worse, if you for example start to do keyword stuffing or repeating the same words over and over again without good thought. For regular content like blogs, people always like to argue about what you need to put in the first place – SEO or your readers. I am thinking you must do both – using simple but consistent and smart SEO and try to write as compelling article as possible to your readers.

If you haven’t already I strongly you suggest to read the first post –
How To Create Popular Blog With Keyword Research, Heatmaps And SEO? from series to get little starting overview.

In that case you’ll get good search rankings because of SEO and trackbacks,comments you’ll get if article will be really good. ( of course, don’t forget about PageRank – new blogs usually don’t rank very well in Google). I must also mention, how good is to establish community, who actively discuss article in comments – Google just love content, which updates regularly. In short – people who add comments to article actually update and continue your article, plus each comment is taken as article update – very important aspect!

Okay, I got a little bit away from main article discussion – this time as promised I am featuring free keyword research tools, which are the most popular now.

Note, at the end of article you’ll find also several non-SEO tools, but still which can be used seriously to optimize your site, help to choose right keywords and understand niche you are optimizing your site to! I suggest you at least visit all of these sites, so you pick your favorite tool because really all tools differentiate a little bit from each other.

Enjoy this article and remember there are several more series to come soon, where I will try to explain how I do my SEO as well as link you to several more useful resources and articles you really should read!

1.Google search based keyword tool

The Search-based Keyword Tool provides keyword ideas:

  • Based on actual Google search queries;
  • Matched to specific pages of your website with your ad and search share;
  • New to your Adwords account (typically excluding keywords matching those already in your account).

I thought it will be better to add official product introduction, than explaining what this tool does with my words to give you good overview.


2.Google AdWords: Keyword Tool

Use the Keyword Tool to get new keyword ideas. Select an option below to enter a few descriptive words or phrases, or type in your website’s URL. This tool gives you approximate keyword search volume statistics for Google search network and because of Google growing and dominating search network, you really can get pretty precise results.


3.Google Insights for Search

Google Insights is a powerful tool that offers features not available on most other free tools. For seasonal or fluctuating niches, you can view stats by year or a specific time period. For regional niches, you can view stats by country, state or even city. The graphical reports are great for seeing trends. One of the only downsides is that they don’t show absolute search volume but instead normalized data that is shown on a scale up to 100. Also since the data is normalized the detailed stats are limited.


4. Google Trends

Use commas to compare multiple search terms – one more great product from Google allowing you to research and compare trends.


5.Free Keyword Suggestion Tool from Wordtracker

Wordtracker helps website owners and search engine marketers identify keywords and phrases that are relevant to their or their client’s business and most likely to be used as queries by search engine visitors.

Use the free keyword suggestion tool from Wordtracker to help your website rank higher in the search engines. This tool can generate up to 100 related keyword phrases and show daily searches.

If you use Internet Explorer 7, or Firefox 2 or 3, you can add the Wordtracker Keywords search to your browser.

Try this free keyword research tool,which is quite usable, but creators limit your access trying to sell you paid version, generally you still can get pretty good overview.


12.NicheBot Classic

Non-SEO tools, but still extremely useful:

13.Synonyms Thesaurus with Antonyms & Definitions

18.Keyword questions

People often type questions into search engines. Now you can find these questions, answer them and get some great search traffic.
