I tried to put down list of few SEO tools, which are going to be useful to anyone who is looking to learn or working on SEO
The Search-based Keyword Tool generates keyword and landing page ideas highly relevant and specific to your website.

The tool goes one step further by tailoring the keywords and other data (such as the amount of competition for the keyword, the suggested bid, and more) based on your language or country/territory settings.
Wordtracker helps website owners and search engine marketers identify keywords and phrases that are relevant to their or their client’s business and most likely to be used as queries by search engine visitors.
Marketers can also determine how many competing sites are using those keywords and can identify the phrases that have the greatest traffic potential.
keyword tool is powered by Wordtracker’s API. You can explore more keywords by subscribing to their powerful keyword research tools.
This tool forecasts the impression count and predicts demographic distributions of keywords. Enter keywords separated by semi-colons and click the submit button.
