any more easy to understand tips on search engine optimization?
Wow. SEO is work, work, and more work. Not difficult work, just consistent work - you can't fit and forget.
Google is your friend.
The important things are:
Content firstly - well written, relevant, and good use of Headers. Content should account for at least 15% of the total page (including all the behind the scenes junk).
Keywords - less important now than before, but still help - your content needs to reflect the keywords of what you do, and choose a few very good keywords for each page - what you offer, where you offer it, and who you offer it to.
Link building - advertise your website all the time. By this I mean get it linked from other sites - twitter, Facebook, quality directories, blog sites, and so on. Reference your site any time you can.
Monitor what your site is doing with Google Analytics. It's free, and it will help.
Good Design - your site needs to be easy to read, and it needs to make people WANT to contact you. It also needs to be search engine friendly - no dead URLs, no cryptic URLS, keep the "depth" of the site to less than three clicks to any page.
Just a few items to help.
