Date apppearing in SERPS

[BrettCollins]

Anyone have an idea why dates might be appearing in search results for a small number of my pages and not others? There is no date on any of the pages themselves and nothing in the back-end CMS indicating dates should appear.

Some of the dates (presumably from when the snippets were originally created) are over a year old and make all the information look terribly out of date.

Any ideas?

Do you have any schema at all?

[DougRoberts]

Do you have any examples you can give us? Keywords / domain etc?

[BrettCollins]

Yep, generally used for videos.

[NaescentAdam]

Is the schema on the pages you have dates appearing on?

Got any examples?

[BrettCollins]

Sure, the domain is Kenwoodtravel.co.uk and the particular keyword that the particular page it's cropping up on is the Antigua landing, main keyword: "Antigua holidays". The problem is occurring on a few other pages as well.

[BrettCollins]

Yeah it is, now that you mention it is on all them. That must be the problem. Any easy way to fix this? I'm not as clued in to this schema business as I should be.

Here's an example: http://www.kenwoodtravel.co.uk/florida/holidays/

[DougRoberts]

I'm not sure that's the case, the only schema I can see on this or the http://www.kenwoodtravel.co.uk/caribbean/antigua/holidays/ page is around the breadcrumb mark-up and doesn't contain any dates.

There are no dates in the sitemap.xml either.

The cached version of the page is the 25th may this year. So I don't see where it's getting the "Aug 22, 2012" date from... does this tie in with anything in the page's history?

The response header has the last modified date set to: "Last-Modified: Tue, 04 Jun 2013 14:42:38 GMT" (The current time)

Grasping at straws here, but are there inbound links from a blog post with that date? (And if there are, would/could that be the cause?)

Do the dates appear on any pages linking to the affected page?

It's a bit of a mystery!

[BrettCollins]

No, there's nothing linking to the page from around that date The dates are only appearing on pages with videos though, so that is presumably the cause, but I can't quite figure it out either.

[DougRoberts]

Do you have/have you submitted any video sitemaps?
