Whether you're new to SEO or an experienced consultant we all prefer automated tools, free when possible, which make our life just a bit easier at times and allow us to spend more time on the creative elements of the SEO work. By successfully using these tools and others, you'll be able to concentrate on what you do best.
Below are some of my favorite tools which I normally recommend on my blog to support your SEO work:
Basic SEO health check and analysis
1. Website Grader by Hubspot - Website.Grader.com is a free SEO tool that measures the marketing effectiveness potential of a website. It provides a score that incorporates elements such as website traffic, SEO, social popularity and other technical factors. It also provides some basic advice on how the website can be improved from a marketing perspective.

learning about SEO is incredibly confusing at times. Thanks to sites like these to help cut through a sea of information to deliver the good stuff!

Do these sites not go against Googles terms of service?

Hi Tony,
I am assuming these services use various APIs (not Google necessarily) and furthermore they don't check particular keyword ranking.
On the contrary, by giving you more visibility on potential issues effecting your site (such as content duplication) you'll help the engines better crawl your pages and thereby consuming less resources.

Nice instruments Ran, but I hate those services that provide false free services asking your e-mail to send you their final report.
The service is free or it's not. It doesn't exist the half way.
Anyway I'll post something about this and include some of the links you proposed.
Have a nice day.

Hi Andrew,
None of these sites require your emails address. If you're referring to website grader, I believe an email address is optional.

Hello Ran,
thank you for this nice compilation - it is a good starting point.
Cheers,

Hi Ran
builtwith.com asked the e-mail to send their final complete report, so I assume that what they shown me was just half of what I could get.
And there was another one that asked me the e-mail, but I dunno remember which one.

nice round up, might as well add senSEO firebug extension http://getfirebug.com/extensions/index.html#senseo for firefox
thanks for list.
9:54PM on 16th April 2009
Great little tools, recommend link diagnosis with mozilla firefox for backlink checking
9:55PM on 16th April 2009
Nice list. I'm not a big fan of toolbars, but I do use the SEO Book toolbar in conjunction with some of the sites you wrote about.
The thing I like about it most is that I can get some basic SEO information right away without leaving the page.

Hi Ran,
thanks for this useful post, i bookmarked it and some of the other URLS you provided, may i add a few other tools that also do the job and I find very useful:
-the 'Live HTTP headers' extension on firefox to check your pages headers and also the 'Flagfox' extension to ascertain the location of the current server. Actually it usually gives the location of the IP which is not always the same as the location of the physical server, but it helps.
-as an alternative to the SEO Browser I have always used the search engine spider simulator from web confs: http://www.webconfs.com/search-engine-spider-simulator.php

Hi! You should also consider http://www.estimix.com They provide a nice summary of the website performance. I trust that you’ll find this very useful cause it seems to use the Alexa traffic information quite well and provides much better traffic information.
