There’s been much debate over the years about whether or not you should include dates in your URLs; Google says it does’t really matter.
You can learn more about this over on the full blog post at Search Engine Roundtable.
For a long time, people have debated whether or not you should include dates in your URLs. For example, if you had a post about the Atlanta Braves should be it:
While dates in the URL can help for Google News, if your site is syndicated there, it doesn’t matter for normal organic listings.
A user asked: “For instance, Blogspot by default puts Day & Month in the URLs. That is ok from Google’s point of view or not?”
Google responded with “Having a date in the URL is fine”
The user followed up “For instance, there are 2 URLs, one with date & one without date. Google will treat them similarly for ranking?”
Google responded with the exact same thing again: “Having a date in the URL is fine”
So there you go. I tend to think for most sites you’re better off without dates, simply to have cleaner looking URLs. In terms of rankings, though, you’re fine either way. Google is more concerned with the quality of your content and other factors.
One important note is that I recommend you don’t change from one to the other. If you have dates now and wish you didn’t, you’re likely best off leaving well enough alone. There are ways to make the switch, but it’s likely more effort than it’s worth.
