These are some SEO tools and resources I use for research. Most seasoned DP members might know about these, so I guess it's mostly geared for newbies, add any that you think is relevant, SEO for Firefox Extension I love this one because it gives you so many resources on the toolbar, it also gives you the ability to see under search results what the PR, links, and other data useful for SEO purposes. Google keyword Tool I use this everyday to search any potential keywords I want to use, it gives you options to research CPC average, monthly search volume, competition so it is very useful, I read about other members using wordtracker, I have not used it myself but might give it a try, anyone uses it? Google Webmasters Tools - This one gives you information about your site performing in Google, the number of backlinks, where do you show in the SERPs, under what keywords, and a lot more information that can be used to track performance with Google, many say it does not give you the whole picture so don't trust all the numbers you see there, but at least you get an idea. Yahoo Site Explorer - This one will give you a snapshot of all backlinks, even if they are no follow so you know who is linking to you. There are many tools out there, these are the four that I use the most. Please share the one that you use the most. Thanks Ruben
I know these all tools but i am daily using Google keyword Tool and Google Webmasters Tools. these tools give me some IMP information about my sites.
I use RankChecker every month to monitor my rankings. You can download this free tool at: http://tools.seobook.com/firefox/rank-checker/
I saw a couple of people mention Google insight, had never heard of it. Googled it and found really good information, about search terms in other regions. Thanks everyone for sharing
