Dear colindolly you are in big trouble!
I have study your site and found some mistake on it although I am not sure that below steps will help you a lot because Google search engine ranking algorithm rely on many factors.
As per your site code review I do not find any issue in code level design that might create problem in crawling and indexing.
1 http://www.aeisndt.com/index.php make it http://www.aeisndt.com/
2. sitemap is not update after 2010. Do the needful as soon as possible.
3. You do not customize your error page and by default hosting server generate "404 - Page Not Found" (hostmonster)
Update .htaccess file to custom error page.
4. Make absolute path for navigation.
5. Access you of <h2>heading tag in your site. Please rework on it.
6. Access use of keywords in you content. Please remove it
7. Now after updating step 1 to 6 please submit your website manually http://www.google.com/addurl
8. The last but the must important factor to get index and rank is link building process (Press release, bookmark, classified, forum, and directory submission and so on.) |
