I am new to the SEO and looking for search engine optimization tool.
I found some seo tools online but I don't know which one to choose.

Does anyone know other good seo software or recommendation?
Many thanks.

Find one that you can work the code manually so you can tweak your content delivery or modify internal elements like Title and stuff. A good quick one that I still recommend is NotePad. ( most people probably didn’t get that one )

I have more than one comment about the uselessness of most SEO software tools; they sell good. ( some more will get what I mean now )

Oh heck.

Software developers often prey on people still hoping to find short cuts in SEO. Just keep that in mind when shopping around for SEO stuff that you don't need anyway. There, now you know.

yeap, i agree with you
the funniest thing (actually it's very usefull) it's when you do Free consultancy to the site owner - what he should do and explain in very high details - he says like "wow thanks, how much i should pay for ya to do all of that?" :lol:

anyway it's good, and i think that if you are the business man (which are actually creating sites for some business) you should not get into the development process or the internet marketing - it's senseless and will just waste your time.

http://validator.w3.org/ is all you need

None of them

No "tool" can do good SEO for you, all of them are flawed with misleading and/or downright wrong information. do you need good Seo process visit

addweb is pretty decent also...

I don't think any SEO software would ever help you to get on top of search engine.
What i will suggest you : to be your own SEO expert, you know your site and your product better so why to rely on other, get up and start yourself all techniques for getting higher ranking in searchengines.

always wanted to ask .... what exactly is validator.w3.org good for? well, i mean in terms of seo-wise, not web-proper-coding-wise

care to drop me a hint? :eek:

Nothing SEO wise directly. But if you can't get your site to validate don't hold your breath about optimizing it for search engines (plus errors in your code can cause parsing issues).

No need.
Dont waste your time on Software in SEO. It is not only useless but also may harm your site.
Nature ways is the best software.

Good luck.
