I saw this tread on another forum, but not one answered they guy. Thought I'd asked the question here: I'm thinking of using this as my robots.txt: User-agent: Googlebot Disallow: / User-agent: Googlebot-Image Disallow: / User-agent: msnbot Disallow: / User-agent: Slurp Disallow: / User-agent: yahoo-mmcrawler Disallow: / User-agent: yahoo-blogs/v3.9 Disallow: / The reason is in order Google, Yahoo, and MSN bot cannot index my page, but the adwords bot (AdsBot-Google) and other PPC bot can. This is for A/B testing, also with SPPC we get tons of different LP version if you make the LP dynamic. I'm thinking if my content get indexed it may lower my QS. Is this the right move? ========================================================== Also, what about stopping the AdsBot-Google (adwords bot) when putting up a campaign...would this lower your QS?
