I have read David Viney's 'Get to the Top on Google's book which I found very helpful and I would like to start my Keyword Research for a new website. The trouble is I haven't found a Keyword research tool (either paid or free) which I have put my trust in yet. Having read many blogs across the web many SEO experts have a differing opinion about what are the best/most accurate tools available.

Would anyone in this forum with an authority on SEO please recommend a tool or may be a couple of tools for carrying out excellent keyword research for SEO in the UK. I don't mind paying for a tool if it will provide good data.

I understand how important Keyword Research is, it would be good if there was an independent Internet body that gave recommendations for Keyword Research tools.

Any useful reply would be very appreciated

Thanks in advance
