Lots of people use WordPress as a content management system (CMS). It's a great tool, has an active user community, and it's free.
You can use it to run your blog or your whole Web site. You can use it as a free hosted service at WordPress.com (with some limitations), or run the software yourself (many Web hosts offer it pre-installed as part of a hosting package). One thing, though, is you still kinda need to read the manual if you want to maximize its value as a tool for marketing your winery and wines.
I was reminded of this while looking at Wine Industry Insight. The "permalink" (URL) of a post at wineindustryinsight.com looks like this:
This is the default, and its format is a dead giveaway that WordPress is in use.
A better format for this permalink, one which could increase the search engine ranking for this post, might be something like:
since search engines tend to pay attention to keywords in a URL.
One thing to watch out for: if you change the permalinks for existing posts, you need to create permanent redirects (HTTP 301s) for the old URLs if you want to preserve the current search engine rank/information about those pages.
This is why it's important to set up your permalinks correctly from the get-go.
