Heading tags have not been used for proper document structure. They have been used to force formatting of the content. In some instances they have not been used as headings at all. i.e. a whole paragraph contained in a set of heading tags.
In some areas, text that is not a link has been underlined. This site is not in English so I can't tell what some of them are really for but assuming they are headings and should have used the appropriate heading tag.
The meta description (on the home page anyways) looks more like a list of keywords than a description.
This line is not required. All pages are indexed and links followed by default. You only need this line on specific pages where you want to change the default.
<meta name="ROBOTS" content=" index, follow" />
You need to go through each page and double check for alt attributes. Some images are missing this.
There is no
- Home link/button
- HTML site map for users and the search bots
from what I can tell.
