The word Blog is short for Weblog and is typically a type of website that has a collection of articles related to a topic that the author is interested in or specialises in.
However a Blog can be used for other things too.
For example there is a Blog on this website.
It is used to pass on useful information and news that might be useful to businesses looking to start a new website or update an old website.
Other uses would be for Reviews, Newsletters, and don’t underestimate their usefulness in generating better Search results by adding relevant quality content to your website.
