I have a static website in which client created city specific pages of each state , but all of city page's contents are same only city name changes, in this website 9 States Pages and in each state 40 city wise pages, all of Page's contents are same so my question is that should i use rel canonical in each 40 pages ?? if yes then i have to use rel canonical in total 360 pages , i am bit confused that this much of tags in each of those pages can raise a flag on Google eyes ??? and after doing this can i get Crawl Error in WMT ??
Please let me know best option and why ?? 1) rel canonical tag in all 360 pages 2) noindex , nofollow in all 360 pages 3) disallow all 360 pages from robots.txt file ..
