30 Keyword Tools to Use for Your Website

Part of having a successful website or blog is targeting the right keywords and phrases. This sounds like it would be an easy task, but with endless possible combinations of words and phrases it can be quite difficult to find keywords that will generate traffic from search engines without putting you in competition with too many other sites.

Fortunately there are a number of tools available online (some free, some not) that can help with the process. I’ve included some basic information about 30 of these tools in this article. Some of these tools are designed specifically for creating and managing pay-per-click campaigns, but they can also be helpful if you’re just trying to optimize your site.

    Thank you so much for this great info.

    I would like mention you for a small correction. keyword elite 2.0 cost 97 bucks instead of 167.

    I like the keyword elite 2.0 because it has more features that are so helpful.

  • James, February 13, 2010

    This is a great post, but you are missing Market Samurai… It’s another one time cost option that is really easy to use.

    Also, I love a tool provided by John Jonas that checks to see if your targeted keywords are buying keywords or informational keywords. Commercial Intent is so important.

    MS does this as well, but this is a free option.. Just google ‘john jonas commercial intent tool’ and you’ll find it….



  • Chotrul, December 12, 2009

    I know this is a pretty old list of resources now for keyword generation for SEO, but just thought I’d give a shout to SEOmoz, who have great tools for SEO in general, including keyword generation. The Pro membership ones are amazing.

  • Terry : keyword services, December 2, 2009

It just goes to show you that you do not need to spend hundreds of dollars on software packages to obtain some decent results although I guess that suites of these types of softwares are always worthi investing in saving time along the way…

    Thanks for featuring this on your site..^^

  • Free Rigntones, April 14, 2008

    I don’t understand how you can say IBP is free … its not free … I think its ok! 9 out of 10 times the emails it gets for you are bad emails. They are all suggestions. It chews up the resources like there is no tomorrow and then you have to try to do it all over again. I think its ridiculous. Why do I need to feed it the competitor list? It should go and get the top 100 or 200 competitors and get its backlinks. There are other tools out there that are much much faster!

  • Mar Matthias Darin, March 18, 2008

    Here is a free keyword tool:


    It searches the webpage and gets 100% revelant kwywords.

  • Jon, March 6, 2008

    Nice list. I’m currently developing my own keyword tool, and have looked at many of those listed above for ideas.

    Hopefully my own tool will make it onto the list one day!

  • Simonne, January 9, 2008

    Did you try to compare results across various tools? I’m a little bit puzzled because I’ve just subscribed with WordZe and for certain searches the results differ significantly from the ones obtained with Wordtracker’s free version.

    My current site never reflected my personality and the communication with designers – well, they weren’t creative enough, – just check out the website and see how boring and non-dynamic it is.

    I need a web design that uses Flash – Dynamic Flash so there is movement and weekly new shot clips posted and about 6 other short clips and an archival system so people can order and pay donation for (paypal) the full dvd of the short (which will have a description written about it.)

    Thank you so ,much, awaiting yur reply.


    Pls reply (i didn’t see any movement in your profiles – and is you use flash & Dyna-flash.) Thank you very much.

  • Vandelay Design, November 12, 2007

    Looks goo. Thanks for sharing.

  • Joshua Wexelbaum, November 12, 2007

    I’ve spent a lot of money on keyword research tools, and so recently I put together an affiliate website which compares the tools.

    I interviewed several of the designers of the keyword tools in order to get accurate information, along with my own research:



  • Vandelay Design, November 8, 2007

    You’re right, it’s a good tool. Thanks for the addition.

  • Brady Freeman, November 8, 2007

    I use google trends all the time http://www.google.com/trends

    This can display search queries based on a 3 year time frame and you can see if the term is gaining in popularity or decreasing. You can also find if a term has certain seasonal popularity like fitness equipment or gardening.

  • Vandelay Design, October 21, 2007

    Cool. I’m glad you were able to find this through a search.

  • TheAnand, October 21, 2007

    Thats a nice list of stuff to do, I was looking for something like this for a long time now. But the happiness of finding a site you know about in the serps is a nice feeling

  • Tushar, September 28, 2007

    Try this Easy and powerful keyword search tool

  • Vandelay Design, August 25, 2007

    Profitable eBay,
    I think I’ve tried all of the free tools. Recently I’ve used the Overture and Google tools.

    Thanks for bookmarking! I’m glad there is some stuff here that you can use.

  • Charleston S, August 25, 2007

    Solid list of research – thanks for taking the time to put these together. I’ve seen most, but there’s just so much information, that I forget. Just bookmarked :)

  • Vandelay Design, August 8, 2007

    Thanks, I made the change. Thanks also for the link back to this post.

  • Marcin, August 8, 2007

    First of all, thanks for including my little bookmarklet in this great resource :-).

    I’ve noticed though that there is a mistake in the price for Keyword Discovery – you say it’s $49.95 per year, whereas it is in fact either $599 per year or $69 per month.

  • Richard Ball, August 7, 2007

    Thanks for including my firm’s free keyword research tool in your list.

  • Vandelay Design, August 3, 2007

    Sorry for the mistake. I’ve made a correction. Thanks for visiting!

  • Jon Miller (Marketo), August 3, 2007

    Thanks for including Marketo! Just one small correction: We include one user for free, so the $49 / user charge only applies if you have multiple users in your organization.

  • Vandelay Design, August 3, 2007

    Thanks for visiting and for bookmarking!

  • Aaron :: miLienzo.com, August 3, 2007

    Excellent resource here – many thanks for sharing.

    Am bookmarking this one now :)
