Net without search engine optimization? Is it possible? Tadeusz Szewczyk of onReact.com says it is very much possible. He shared a bunch of techniques to do it:

Discover your niche
Be different, choose a topic or product that not everybody else already covers or sells. Discovering it is not to be confused with "keyword research" as in conventional SEO.

Use Wordpress
Instead of "on page optimization" you can install Wordpress that is search engine friendly out of the box. Wordpress is not only a blog software, you can use it as small scale CMS and it will suffice for most average websites.

Create a killer CSS design and submit it to CSS galleries
Traditional SEO is all about link building or getting links. Sites doing SEO often look crappy. These days people link web sites that look great just for the sake of the design.

Allow trackbacks, use dofollow
Blogs thrive in connection with each other. The best way of connecting blogs is the trackback function. Install the dofollow plugin in order not to treat other bloggers like spammers.

Socialize, write comments and link other blogs
Link and mention other blogs and bloggers in your posts. Also commenting in other blogs is much appreciated as blogging is not a monologue if it's done right.

Include social media on your site, use social media yourself
Include buttons to your favorite Social bookmarking services like del.icio.us or Stumple Upon. Be careful with social news sites like Digg or Reddit. They may crash your server and/or cost you lots of money by driving tons of useless traffic in short periods of time to your site.

Write your own content, say something new, express yourself
Write about stuff out of your niche that you know about. Write your own content, do not just post links to other sites. Say something new that wasn't already said by everybody else. Express yourself, do not repeat yesterday's news.

Compile what you know or what others said and publish it
If everything was said and done already in a particular case, compile it and create a list. Top list are the best solutions as a "200 Wordpress plugins" list is just too big. "10 indispensable Wordpress plugins" is far better.

Contribute to your favorite online publications
Do not just publish at your own blog or site. Contribute to other publications that cover your topic. Try your favorite ones first, as you probably know exactly what kind of topic they would like. Most publishers will link to your site

Add new content at least every second day
Add new content often enough to create a stable readership. People that visit your site once a month might forget about it. It's not always necessary to post every day but if you write a real blog do it at least 3 times a week.

Pretty nice methodology. But do you think it's really SEO-free?
