What are the best SEO tools are you using in your projects?

Been using google trends for quite a while. This is actually a long awaited update/overhaul. So glad to see the direction google is taking with design and communicaton style. So clean!

It's great to see that Google took the step to make a complete refresh to Google Trends.

Great tool. It's something that can change your rankings in Google dramatically - if you use it right! Luckily, they have in-depth guides.

Great app for ongoing monitoring of your website's positioning / SEO ranking. Easy to use, even to those not very familiar with SEO.

It's a beautiful product for advanced technical SEO that you can feel confident using. It provides solid recommendations and is very easy to use. I picked it up in a matter of minutes.

I used Sitebulb for one month during the Beta period. Very nice product at launch that I'm certain will be updated regularly and become even more valuable over time.

Their query based pricing makes the product almost unusable. They'll charge you for every DB query they post -- every click will cost you the number of DB queries that action requires. That's pretty random and dependent on how efficiently they do that (I don't see much incentive to optimize that). Moreover, reports you "purchase" are not cached i.e if you request the same report you just saw/purchased, you'll be charged again.

I have been using SERPSTAT for about a year and normally use SEO PowerSuite and Google tools. I love the ease of use of SERPSTAT and the information it pulls when doing keyword research or looking at the keywords related to an added site. Great set of filters which make searching easy.

Can't wait to see how it evolves as more people grab it.

FINALLY - a tool that shows an approximate value for search volume without having to burn a hole in your pocket every month. Despite its limitation (which is understandable because it's a free tool), Ubersuggest is a keyword tool that cashstrapped marketers and SEO specialists can't do without.

I need to come back to this and do more testing with a specific purpose is mind, but I just ran it quickly to be sure I wouldn't forget it - and I won't!

I love SEO PowerSuite and Website Auditor is a key piece of that package. This is one of my first tools to process a website when I am doing SEO for a client. It gives you a good baseline and overview of what to fix in the technical side of a website. The single page reports help refine the onpage SEO and the reports are great!

Thanks!
