Microsoft claimed that it is not just mammoth sites such as microsoft.com and msn.com that can boast infinite URLs, but large business sites can too.
Writing on the official Live Search Webmaster Center blog, programme manager Jeremiah Andrick claimed that less is more in terms of large sites operating to their full potential.
"By producing lots of content, a site exposes a huge surface area for the search engines to crawl.
"This can lead to sub-optimal results or underperforming pages," he said.
A neater and more streamlined content base is therefore essential to avoid the risk of duplicate URLs "diluting" a site's link equity.
Another way for a webmaster to ensure a large website performs well in terms of appealing to its users and getting high search rankings is to only use absolute links.
Doing so, Mr Andrick claimed, will guarantee consistency in a site, which in turn will secure its performance.
Meanwhile, Google recently suggested that web developers could boost user experience on their sites by enabling its iLike playlist gadget, which comprises an interactive music soundtrack chosen by users.
