Hi Mike,
I've just done a quick crawl of your site with Screaming Frog and I can already see quite a few issues. I won't bombard you with all of them but I'll list a few things you can start with:
- Your URLs are a bit messy. There seems to be a pc subfolder somewhere in the site architecture. You may want to remove this folder so that you do not have /pc/ within your URLs.
- All your pages seem to be contained within a /store/ sub folder. You may wish to change this so that only the store pages are contained within this folder and the rest of your pages are contained within the root. This would remove the unnecessary /store/ from all of the URLs.
- Your home page goes through a messy chain of three 301 redirects to the eventual page http://www.wheelchairparts.com/store/pc/home.asp I would remove these redirects so that your home page reads http://www.wheelchairparts.com/ - much neater and user/search engine friendly
- Home page title is too long (>66 characters) and is stuffed with keywords. In fact all the page titles appear stuffed to the brim with keywords. I would change these to be more appealing with your keyword included only once.
- Some of your meta descriptions are too long (>156 characters). I would consider modifying these too be within the character limit.
- Consider removing the Meta keywords tag completely. It is unnecessary and you seem to be spamming it anyway.
- You have several duplicate pages. E.g. http://www.wheelchairparts.com/store/pc/viewCategories.asp and http://www.wheelchairparts.com/store/pc/viewcategories.asp. You will need to fix this issue.
Anyway I think that's probably enough to get going with for now. Hope that helps!
Adam.
