Working on Search engine optimization (SEO)

I’m trying to work on the search engine optimization (SEO). I found 2 links and I have followed some of its recommendations. It has worked a lot, now Google finds it with the main key words of the business.

1. Posicionar Web: http://www.posicionar-web.info/
2. Zona Libre:  http://www.zonalibre.org/blog/salvaje/google.html

The activities I have done:

1.- Validate the URI. I started with 8 errors and now I obtain a green light: “This document was successfully checked as XHTML 1.0 Transitional!”

http://validator.w3.org/

2.- Add a sitemap.xml file. Before to do this I found the way to check that all links were properly included in this sitemap.

http://www.xml-sitemaps.com/ (limited to 500 entries)

http://www.check-domains.com/sitemap/index.php (unlimited)

3.- Add a robots.txt file,

4.- Add the web to DMOZ directory: http://www.dmoz.org/

5.- Add the web to Google directory: http://www.google.com/intl/es/addurl.html (it’s no longer available, Google closed it). But you can use this URL accessing from your gmail account, and then do a request to add it:

https://www.google.com/webmasters/tools/submit-url

6.- Add your web site to bing:

https://ssl.bing.com/webmaster/SubmitSitePage.aspx
