A website, usually maintained by an individual, with regular entries of commentary, descriptions of events, or other material such as graphics or video. Entries are commonly displayed in reverse chronological order (Wikipedia)
But on Digital Inspiration today, I discovered a much better meaning for this word: the initialism of Better Listing On Google!
Blogs do tend to do better than static websites in search results as they are updated regularly with new content, and are more likely to be linked to by other blogs.
These days, many online businesses choose to add blog functionality to their site in order to gain more exposure and achieve better rankings in search results. Also, as blogs are updated more frequently than other types of websites, they benefit from being indexed more quickly.
Personally I prefer this new definition of "blog" to the elusive (and sometimes vague) definitions provided by other sources!
