I used to use the service of a SEO company. However, after a year I wasn't very impressed so I've taken that on myself (what a headache). However, I'm going through all of our pages and noticed they used A LOT of different types of meta tags (besides the usual - keywords, description, etc).
Does anyone know exactly what the purpose of meta tags like the ones below are for....who uses them (spiders)...and if they help in any way?
I've looked online and kind find a "definition" of these meta tags and why someone would use them. They seem more like a waste of space and I'm thinking about yanking them, but just wanted to check and see if they really are useful.
These are examples of the Dublin Core [webmasterworld.com] meta tag initiative. To date they seem to mean nothing for SEO - but read the linked thread and you'll get an idea about what they hope to do.
The first one is for SearchBC [vancouver-webpages.com], a (defunct?) search engine that only indexes sites in British Columbia. If your has nothing to do with BC, your SEO was robbing you blind.
The rest are Dublin Core [dublincore.org] metadata elements in an out-of-date format. Completely useless, except for a couple of search engines so obscure and useless that I can't remember their names.
