I have a point 2 site, What kinda of words should I use in the meta tag and descriptions and keywords to help increase my ranking. I googled my city and the word real estate and some other words I have in there and it still is not showing up. Any suggestions?
Thanks

Google does not really use meta tags when ranking sites. They use on-page content and off-page factors such as links pointing at your site and the text used in those links.

So, you need to make sure that the keywords you want to be found for are used in your site's content and in the links that are located on other sites pointing to your site.

That is a simplistic answer to something that takes a lot of time and energy

Doug is right, meta tags don't really do much for search engine rankings anymore. One thing you want to consider though is what keywords you are trying to target. If you are trying to rank high for 'real estate', you better have a lot of time and money because that is an extremely aggressive phrase to rank for. To have a better chance at ranking high in the search engines (as well as get better-targeted prospects) is to optimize your site with longer, less-searched phrases. These kinds of phrases have a lot less competition and will be easier to achieve high rankings in the search engines. In your case, I would recommend trying to optimize your site for phrases like 'Indiana Real Estate' or 'Indiana Realtors'.

I added a couple of keywords to my meta description and after the next cache I was #1 for those keywords. Prior to adding them I was nowhere for those words. Those kw are in my content and they are not in any links. So I think IMHO, from my limited experience, that meta descriptions are used by the big g for placement.

They are there to use so why not use them?

Google does use the description tag and words in that tag (up to a point) carry as much weight as if the words were on the visible page. Merely putting competitive real estate keywords in the description tag is not going to result in ranking well for those keywords - and I believe that is what Livechatrealtor was asking.

It is still a small factor for google, but for the other two major SE's I believe it is still required and necessary.
