Is SEO still worth it?

I've been asked to do a lot of SEO for people in the past, my english and german sites, all have PR3-7 but, honestly, I don't think it's worth the hazzle any more.

I bought the Webposition software, it helped a lot in doing submissions faster.

But besides submitting and writing a good Meta Description and title.

There's not much that I still find worth doing, mainly because the web has transformed so much.

Of course "Content is King"  that still applies but Content has changed so much, it's dynamic, It's created by it's Users and shared by it's Users.

If you have loyal Users that contribute, like for most websites now, you have a constant traffic flow, you will get new Users and more page views.

They will post about your site on their blog, link to their profiles and content on your site.

This is all the SEO you can wish for.

It's a mail to a good and popular friend that will jumpstart your site these days.

However if you still want to create all the content yourself, SEO is your thing.

Though I doubt you'll still have time for that .

Then I have some suggestions,

Install the google toolbar, go to your competitors site, check the backlinks,

add to all the sites that link to him for free.

Post in their forums, use your signature as link.

Post in other Forums, and register your site dmoz.org and yahoo directory.

And place a link in all relevant wikipedia pages.
