Not really a fan of Infinite Scrolling, but it does not make sense to apply it on just every other website.
Infinite scrolling make sense on Facebook, Twitter or Google Images. User on these websites are not searching for something in particular. They are just browsing to find interesting stuff.
Whereas infinite scrolling on Google Search won't make sense because the aim of search engine is to provide exactly what user is looking for on top position. If a search engine can't do that, then it means it's going down the path of Yahoo. Also infinite scroll may affect the performance of your website's speed and load time. It might even become an abomination on slower Internet. Another downside is that user cannot access the footer links.
If you still want to use infinite scroll on your website, like on blog, then my recommendation would be to use a "load more" button rather than forcing user to go through infinite scrolling.
