A complete list of keyword suggestion tools

Using the best keywords for search engine optimization is a very important thing when you promote a web site. The purpose of this research is to find something that your possible clients search when they are searching to buy your product, but you should also pick some keywords that have little competition.

For example "free stuff" is a search term that gets thousands of queries every day, but most of the sites in the top results have thousands of incoming links so it would be very hard to compete them, while a search term like "free cellphones" or "free computer stuff" could be easier to chase.

With that in mind I decided to write down a list of keyword suggestion tools. These tools can help you find information on many keywords (eg. how many times a phrase is searched per day) or find you some relative keywords (eg. "free stuff" is relative to "free ipod")

Bellow is a list with all the keyword suggestion tools I found. If I missed something please let me know :)

1) Google Adwords Keyword Tool.
This is the official tool from google adwords. A great thing that this tool provides is the "site related keywords" which can help you see what keywords are probably used by your competitors.

2) Overture Keyword Selector Tool
This tool provides related keywords using data from Yahoo's ppc program.

3) NicheBot classic
This used to be my favorite tool. It is the original nichebot.com tool which displays information from overture and wordtracker but merged.

4) Trellian Free Search Term Suggestion Tool
Another good tool to get keyword suggestions.

5) Geoland Search Engine Queries
A keyword suggestion tool that displays data from several search engines.

9) Niche Watch

11) MS AdLabs Search Funnels
An interesting tool to see how people search a certain keyword and analyze the search behavior that users have.

12) BRL Keyword Suggestion
This is one of the best tools I found. It uses data from 7 sites to display suggested keywords and estimates on them.

13) Submit Express Keyword Suggestion Tool
A keyword suggestion tool that uses data from wordtracker and keyword discovery

14) Google Trends
Google trends is great to use after you find some good keywords. The tool will display charts on the search volume that each keyword has. The bad thing is that they don't display charts for every keyword but it still helps a lot.

15) Yahoo Buzz
The same with google trends but this is using Yahoo's search engine for the results and it is categorized.
http://buzz.yahoo.com/

16) Google Zeitgeist
This is the newest tool from Google which displays top queries from the Google search engine on weekly basis.

17) Lycos week's top 50
The top searches from Lycos on weekly basis

18) Google Suggest
This is not really the best tool but it can help a little. While you type a search term the ajax driven form will display some suggested terms.

19) SEObook Google Suggest Keyword Suggestion Scrapper Tool
This tool is using google suggest to display results, but it also give some extra information

BFTUK your tool has been added. Sorry for the delay, I didn't noticed your post before :)

Bylla, the tool is based on the overture database, when the database connection is not working I get not results to my pages, sorry

While not exactly results on demand, this can give an idea of what is hot at any given moment...

would be cool if someone could figure out a way to capture some of that data.

these are all free tools?

Yeah all of these are free tools :)

YMC, I guess it wont be hard to get the xml feed that this flash is using (with a sniffer or something) but there are already tools (eg. google trends) that give you the same results.

Other than Overture, do you know any keyword suggestion tool that gives the number of times that keywords are used by searchers?

To be honest I don't remember but I am sure that some of them display number of queries.

Thanks for the huge list

We don't use these tools very often we prefer good old research. Having said that this is a very completes list... Very good work indeed!

Wow thanks for the long list.

But the Google Adward Keyword tool is one of the best tool from them.

This may turn into one of my favourite tools. Many thanks for the link. (It didn't require that I open an account; they must have changed it.)

this is Superb work man!!!! I only know about google adwords but  you have shown so many choices I would like to give it  a try.Thanx.

as usual great list...this helps a lot...keep on posting

Very full list of tools, collection, Thank you for sharing

Thanks Nick. May I ask have you ever tried semrush and what do you think about that tool?

Fantastic list!  A little out of date now, but still plenty of great info.

Great List Thanks. I need to know one more thing where do i found the local keyword suggestion tool like i target california state and i need to check the amount of traffic generate monthly on that keyword in california state.

I wonder how different terms for the same item's are factored in... such as a soda in the south is a pop in New England, or plastic sheeting in Maryland is called visqueen in Florida.  Are there any sites that directly address regional differences in keyword selection for SEO?

thanks for the info

That was a wonderful list!It is very helpful.Thanks for the shearing.

They are cool and I really like using a combination of them because every application might have its own positive and negative aspects but once you start testing the other programs, you would be gaining better results.

Pleased to help our Australian members!

Great share, thanks a lot... would it be fair to say the tools are sorted by importance (at least from your personal point of view) as the google adwords tool is at the top?

Thanks for sharing the list.... cheers...

thank you for the list, great information!

Nick, thanks for the list.  A couple of tools are on it that I was completely unaware of. 

Thank you so much for the list but I prefer to use Google Adwords..
