I have a situation with my sitemap where google bot, and all bots cannot crawl my products. I get a 404 error. They can crawl all pages, except my products. I have checked the robots.txt, but that is not the problem. I even had my webmaster do the metatags for canonical links for google. Google is particular about duplicate pages. I dont know what else to look for in a solution.
I would need an SEO expert that knows coding or behavior of the bots and crawling. Be able to troubleshoot, diagnose and fix the problem. Ill pay $25.00 for the fix.
