How does using period after .com affect the rankings of a site?

[sillychinna]

My client's site URLs ends up with a period after com. For example www.abc.com./keyword.html and this is the same for the whole site. Still we have some 20-30 keywords being ranked top in Google. Can somebody, please tell me whether it affects the rankings.

I don't see how it could affect the rankings directly - but I would worry that a site so badly misconfigured probably has other things wrong that might affect the crawl - and that will affect rankings

It's one of many Canonicalisation and Duplicate Content issues, and one that is easily fixed using a simple site-wide 301 redirect.

You also need to be aware of other stray punctuation caused by badly designed auto-linking features in popular forum, blog and CMS software, as well as appended port numbers in URL requests.
