Removing date from articles - Ranking impact?

[serenoo]

My website has about 50 pages. I add one or two pages every week. Every page has at the bottom this sentence:
Last modified on [date]
I would remove this sentence from any article of my website. The date appears on any snapshot of mine on Google searches. I cannot remove the sentence for one page and check what happens cause it is a common proprierty of the CMS, so I have to remove it all at once. Could that impact negatively on my ranking or Google will ignore it?

We will see our date update likely this week. So I would guess movement in the SERPS coming within 7 days after that. I will post the results likely on my Blog with images, but also without images here.

Date Showing up in Google SERPs
I have a site that advertises my professional services, and I just noticed that the Google snippet in search results now contains an old date on multiple pages. The site has a blog, but these pages are not part of it, and have no date indicated on the page or in the meta data. The actual last modified date is a couple of days ago, but for the homepage Google is showing 2008. Any ideas why this is happening and how to stop it? Ranking for some queries has dropped significantly.

My bad. It looks like my CMS is adding schema to the page identifying some of the content as a blog blog post. Removing that should fix the issue.

I also have pages with schema type Article that are now showing a date. That appears to be hard-coded into my CMS (Joomla) so looking for a plugin to fix it.

Note to CMS designers, please stop making SEO part of the core, ty!

I think it *does* have a very significant effect on SERPs. The proof is in the pudding.

Perhaps ... then again, as Yamato said early 1942 "I can run wild for six months ... I fear the sleeping giant awakes..." (paraphrased).

Google's JOB (if you want to call it that) is CONTENT. If a page does not change, other than a new date, then it is the same content and will eventually be ranked that way and if nothing changes over six months except that date it will ranked even more harshly.

CHANGED content (updated) is different and a new date, or at least one more date appended, makes sense.. Just don't think putting a new date on unchanged content is going to be a boost in the serps.

And that ytube comment above? That is copyright issues and has nothing to do with "new dates" other than g hasn't nuked those infringing vids yet.

We have officially changed the templates on our How To Articles. All pages are updated. In the next week to 10 days I should have pretty decent mini report for everyone.
