The 30 Free SEO Tools You Must Know
Recently a “101 free SEO Tools that don’t suck” list went popular on Sphinn. I love 101 items lists and I love free SEO tools especially if the tools “don’t suck”. While checking out the list I’ve encountered some tools I haven’t been using much or been familiar with at all. On the other hand I was missing some tools I use daily. When I noticed that the list actually contains SEO tools that measure the so called keyword density I finally decided to compile my own list.
Here I want to focus on those few free SEO tools you must know to be able to practice SEO in a meaningful way.
Using 101 tools for whatever purpose is not productive. At the end of the day you got to find your set of say 10 or 12 tools you’ll use. Everything else is just playing around and wasting your precious time. Thus this list will be the size of the usual SEOptimise list, approx. 30 items. I’ll concentrate on free SEO tools here as everybody can test them this way. Some of them are freemium that is they offer basic functionality for free and make you pay for the full fledged product.
This list of the 30 free SEO tools you must know will be a mix of
- web based tools
- stand alone software
- Firefox extensions
Keyword Research
- Google Insights for Search
- Google Adwords Keyword Tool
- Google Trends
- Wordtracker SEO Blogger
- Wikipedia article traffic statistics
Site Check
- Google Webmaster Tools
- GSite Crawler
- Google Website Optimizer
- Yellowpipe Lynx Viewer Tool
- Pingdom Tools
Link Tools
- Yahoo! Site Explorer
- Xenu Linksleuth
- Majestic SEO
- Link Diagnosis
- Link Harvester
- Social Media for Firefox
Ranking
Analytics
Various
- googlebar (not Google Toolbar!)
- Quirk SearchStatus
- SeoQuake
- SEO for Firefox
- SEOpen
- Quarkbase
Take note that I did not mention some of favorite tools because they offer no free version. Also it was important to me that you don’t need to register to use these tools. All of the tools do not require a sign up or log in with the exception of a tool by SEOMoz which is a highly trustworthy SEO provider.
Many thanks to all the knowledgeable SEO practitioners on Twitter who contributed to this list, in no particular oder:
@SEOSEM
@supaswag
@SEOHolicc
@remarkablogger
Of course this list is highly subjective. Plus, I’m quite sure I forgot and left out a tool on purpose you rather would want to see in a “must know” list. So make sure this tool gets a mention too.

Great list of super useful resources. This is going straight to my del.icio.us account. Thanks.
July 30th, 2009 at 8:52 pm
Great list. Some of these I already use, but it never hurts to try other options. These will come in very handy. Thanks
July 30th, 2009 at 8:59 pm
could you please list the paid ones as well ? greatly appreciated :)

Interesting Post! As of now, I know only part of the SEO tools. After seeing your article, I am aware of remaining tools. Thanks a lot :)
July 31st, 2009 at 5:39 am
Great list. I would add: http://www.websitegrader.com for analyzing your site’s ranking vs your competition and http://www.crazyegg.com for analyzing user experience via a heat map.
July 31st, 2009 at 1:08 pm
Wow man, this is an awesome list of SEO Tools. It helped me a lot. Thanks for sharing.
July 31st, 2009 at 1:26 pm
Thanks all for the feedback! Much appreciated!
Angela: Thank you. Both of them almost made it, Crazy Egg does not offer a free version though. Website Grader is a great tool for the average webmaster but I don’t use it as a SEO. I only trust my own judgment when it comes to grades. For instance it say “No Meta Keywords Found” on my page.
July 31st, 2009 at 1:35 pm
I’d also add the FireFox plugin Web Developer… great way to get insight into the On Page SEO factors… my favorite is the “disable cache” so that my changes aren’t held in limbo!
And of course Firebug too, for interactive changes, and speed testing.

I was at a tech roundtable the other night and our resident WordPress guy said he swears by the All In One SEO plugin for WordPress. Said it seems to yield great results for him.

Thanks for the list, Tad, you showed a couple of new tools to me. I’m going to check them out. Also I think the free edition of SEO PowerSuite tools could be added to your list
August 3rd, 2009 at 1:51 pm
There are some great tools out there when it comes to SEO and online marketing. I know the wordtracker labs have some really great stuff out there.

August 4th, 2009 at 10:03 am
Great List. We use most of these now but I’ll give the others a look. Thanks.
August 4th, 2009 at 11:08 am
Hello everybody. Thanks for the feedback.
# Web Develeoper is a good idea.
# Firebug for SEO purposes? Nice to have.
# seomoz.org/term-extractor is great, the other two are OK but not worthy of this best of list IMHO.
# Clicktale is a good idea as well but its free version is very limited.
# myIPNeighbors.com is useful but not indispensable for SEO I think.
# Link Voodoo is weird, it makes you download a php script to your computer. I won’t allow that for security reasons.
# SEO PowerSuite is fine but it doesn’t let you save your inputs or results in the free version which is very limiting. Also their GUI fonts are sooo tiny I barely can read them.
Did I overlook a suggestion?
