Really dreamweaver doesn’t come into the equation.

SEO isn’t just about keywords. The keywords meta tag is practically redundant and doesn’t help much for SEO listings.

You need to concentrate on a good <title> tag – Try using 3 words that you would expect someone to search for to find that page.

A clear <h1> tag – Make sure this corresponds with your title tag.

Make sure you page name uses the keywords in your title and h1. For example /my-keywords-here.html

Also add plenty of content <p> along with lightweight XHTML and CSS. This will reduce the code in the page and give the text content higher relevance.

You also have to take into account listing your site in social networks and directories and/or swapping links with other good related websites.

normally used it meta-tags (http://www.w3schools.com/tags/tag_meta.asp) just place them in the header of your pages (switch to code view)

It doesn’t answer your question, but I wonder why so many people give themselves so much work with their website.
I built my own website (dedicated to a late best friend) – domain/site free from Microsoft Office Live – submitted it to Google myself. It appeared on Google just three weeks after launch (search HORTENSE ELLIS) and has remained at #1 for over two years now.
Never bothered with anything like Dreamweaver
