As some have pointed out it depends on what you mean by SEO. I work as a web developer and I'm constantly asked this question, "Do you offer SEO services?". "No", is my usual reply after I ask them to clarify what they mean.

Most folks reply that SEO is getting their page/website ranked "number one" in Google. They'll point out this company or that company that says they can do it for $xx.xx dollars a month. SEO has become synonymous with the "snake-oil" salesmen of the late 19th and early 20th centuries mainly because they don't understand how Google's algorithm actually works and how they, Google, continually work to improve it. I believe even DreamInCode's ranking dropped when Google changed the algorithm... I think it was in the D.I.C. news letter or a blog post...

There are very simple basics to improving your sites page rank. Content Content Content.
1. Have relevant content on the subject matter (keywords) you wish to target. Having a domain name that fits your keywords does help too, but it's not essential.
2. Follow best practices for coding your HTML, heading tags, no simple "read more" links, meta descriptions and keywords that actually match your pages content (somewhat less relevant as Google tends to ignore them because of keyword spamming but this could change) etc...
3. Update your content/site regularly. If you think you're going to publish a five to ten page website, never update the content and rise to the top of Google search for "home care" well good luck to you.
4. To a lesser extent engage your community, setup a Facebook page, Twitter account, blog. If you have multiple brands within the same company and you can "cross pollinate" do so, but your links have to be relevant.

There are no tricks, no silver bullets. It might work, (Black hat & grey hat techniques), short term but long term all you will have done is hurt your site and lose money.

I don't like the change Google made for sponsored Ads sometimes being at the top of a search page but you can opt-out.
