Google takes web page loading speed into account now when ranking web pages in search results.
If I move my blog to a different web host that's faster and more expensive, will it help?
Using a faster web host or a CDN might enhance your speed, but increasing server speed alone may not be enough. The most common cause of slower loading speed is rendering time, not necessarily the time it takes for a page to get sent to the user. Be sure to fine-tune your site and implement some options to reduce rendering time for all page objects. It is always a good idea to explore options for making your site faster for your users.
