@afun604 I’ve seen blogs with anywhere from 5 to 50 categories listed in their sidebar. The way I like to think about categories is (1) will you have a sizable amount of posts under a category? If not, then you might want to see if the post would fit under an already established category. (2) Do the categories represent your main blog theme / keyword focus?
In your case, categories like Buying a Home, Condos, Finances, First Time Home Buyers, Green Real Estate, Mortgages, Open Houses, Realtors, Rental Properties, etc. fit your main site theme for real estate.
Snowbirds, storm, winter, holidays, etc. seem like they don’t necessarily fit and the one post under those categories could fall under home maintenance or home owner tips. Also, the post under Shopping is really about Mortgages, so it could go under the mortgages category. And the post under Holidays could go under Business Tips.
So maybe go through your posts and narrow down which ones could easily fit under categories that are established, that way when someone clicks on a category, they will see lots of posts on that theme and not just one or two. Also, check out blogs by competitors to see what categories they are using. That may help you in your category choices! :)
