Welcome to the Q&A Forum

Thanks Alan, Wigas and Tommy for your in-depth responses.  Really appreciate the insight!

Alan - no notifications on Webmaster Tools.  Feel like I'm between a rock and hard place with the spammy links.  Google does say if you upload another file it will completely override the first disavow file, so perhaps I should consider uploading a new file with only a couple of bad links, thereby negating the original file with over 800 spammy links.

Wigas - Crawled through Moz showing over 100 critical fixes including configuring attachments as no follow/no index with redirect to main site. Need to work on improving the backlinking!

Tommy - Disavow is just a mystery. Bottom line probably is if you don't have any warning notice in Webmaster Tools, don't disavow, just improve. Will revisit title-tags and image weights for sure to improve response time.

Certainly have a big mess to clean up!

Thanks again!

My website was on first page google couple of months ago, now nothing. Shows up in Bing page one. Some queries/pages still showing OK, but some not at all. Example "residential elevators illinois" found nowhere. http://www.accesselevator.net is the website. Have found 900 poor quality links and used disavow tool. Any further suggestions? Their Page Rank also went from a 3 to a 2. Implemented nofollow on all outgoing links. Need advice.
