Webpage Generation Time
It is Important to keep page sizes user friendly. There are still many users on the Internet using slower speed connections. It is hard for them to browse through your site when it takes an age to load. Spiders see this as a factor in determining rankings. If your site is not user friendly, it is possible to be penalised.
Having pages with thousands of words is a big No. It is important to keep them small, and separate the pages accordingly. It is also Important to monitor the sizes and number of images a page has. Images can take a long time to load and add to the frustration of many users.
Slow page generation can also be influenced by a slow server. It is important to have a good, reliable server in order to have adequate page generation times. If your pages are slow, and you believe you have small pages, it is best you contact your host.
