I am sure the title not clear yet but let me detail apart from keyword choosing do you use other tool to help your site rank higher in Google search result?
If you're referring to tools to get on top of SERPs - I'm applying traditional techniques for that and I won't let the softwares do the marketing part for my site. but if you're referring to useful tools for the SEO, then some of my trusted companions for that are Google Webmaster Tool, Google Adwords Keyword Tool, Google Analytics, and StatCounter to name some..
well, try the IBP tool. Internet Business Promoter. It is a nice piece of software that does some of the SEO work for you. Not perfect, but it is nice! Around $250.00 bucks though.
I second what you said... I go about SEO the good old way, working hard and without software... Now, when it comes to useful tools to assist in SEO then those are pretty much the standard that everyone uses.
I use SEO Powersuite. For most of my SEO needs. link-assistant.com btw, if you use Wordpress, take a look at a new plugin that just came out... SEOPressor. Huge timesaver for on-page seo. There is a link in my sig. Here is a detailed demonstration. http://www.seopressorplugin.com/seopressor-plugin-review Its a seriously good tool. No hype. I was using it since it came out in test release.
Thanks for the reply. I have been good experience with google webmaster tool but i want to know if we could use other soft to automatically optimize. i have found blackhatlink pro is the best but i am not sure will it work or not as it only get exchange links with other ppl site
