Hi Paul, welcome to the forums. There are several points here. Many wysiwyg software packages use their own layout for meta tags and often put them where they feel they ought to sit. Not always SE friendly. A raw HTML/text editor (preferbly not notepad) will allow you to put the tags in the most efficient positions. On your site at the moment, tags and title the best presented spider food. I'm not familiar with the package you are using so cannot comment on what it does to the tags. Perhaps someone else in the forum can comment. Spider visits (or lack of). It is not necessarily directly related to your existing tags, although the wrong tags will send spiders away, you should still see them visiting in your site logs. This is assuming you have promoted your site.
How often did you see spiders before? How often do you promote the website?
