Well I sort of get them. I know they are keywords, linked to what the post is about. I even get the difference between categories and tags I think.
What I am unsure of is, does a tag have to be one word, or words that are together, like 'pain' or 'back pain' or can it be/should it sometimes be a sentence, or several words?
for example, one of my posts is about returning to work while in medication and with back pain which is now a disability. Do I put the tags in seperately as 'work' 'back pain' 'disability'. or would I put 'work and disability' as one tag? and 'work and back pain'.
Have I even explained myself properly?
And another question, which might need to be a seperate thread - how do I highlight the key words in the sentences, to make them bold and stand out for google spidery thingies to pick up, you know the whole SEO stuff, but so they are only bold for SEO/searches and no bold in the post itself? You get me?
this is soooooo complicated. And I am not even doing a self hosting site.
