Is it possible that Google may have erroneous indexing dates?
-
I am consulting someone for a problem related to copied content. Both sites in question are WordPress (self hosted) sites. The "good" site publishes a post. The "bad" site copies the post (without even removing all internal links to the "good" site) a few days after.
On both websites it is obvious the publishing date of the posts, and it is clear that the "bad" site publishes the posts days later. The content thief doesn't even bother to fake the publishing date.
The owner of the "good" site wants to have all the proofs needed before acting against the content thief. So I suggested him to also check in Google the dates the various pages were indexed using Search Tools -> Custom Range in order to have the indexing date displayed next to the search results.
For all of the copied pages the indexing dates also prove the "bad" site published the content days after the "good" site, but there are 2 exceptions for the very 2 first posts copied.
First post:
On the "good" website it was published on 30 January 2013
On the "bad" website it was published on 26 February 2013
In Google search both show up indexed on 30 January 2013!Second post:
On the "good" website it was published on 20 March 2013
On the "bad" website it was published on 10 May 2013
In Google search both show up indexed on 20 March 2013!Is it possible to be an error in the date shown in Google search results?
I also asked for help on Google Webmaster forums but there the discussion shifted to "who copied the content" and "file a DMCA complain". So I want to be sure my question is better understood here.
It is not about who published the content first or how to take down the copied content, I am just asking if anybody else noticed this strange thing with Google indexing dates.How is it possible for Google search results to display an indexing date previous to the date the article copy was published and exactly the same date that the original article was published and indexed?

Thanks Doug. Really an eye-opener.

Thanks Doug for your response. It really cleared up the questions I had about that date Google shows next to the search results.
I was not able to find official details about it, all I was able to find was different referencing as the indexing date of a page.
But I knoew here in the MOZ community there are people who really know things, that's why I asked.
So that date is just Google's estimation of the publishing date, not the date Google indexed the content!
Thanks again for taking the time to answer me!

Hiya Sorina,
When you use the custom date range, Google isn't listing results based on the date they were indexed. Google is using an estimated publication date.
Google tries to estimate the the publication date based on meta-data and other features of the page such as dates in the content, title and URL. The date Google first indexed the page is just one of the things that Google can use to estimate the publication date.
I also suspect that dates in any sitemap.xml files will also be taken into consideration.
But, given that even Google can't guarantee that it'll crawl and index articles on the day they've been published the crawl data may not be an accurate estimate.
Also, if the scraped content is being re-published with intact internal links (are these the full URL - do you they resolve to your original website?) then it's pretty obvious where the content came from.
Hope this help answer your question.

Hi Sorina,
I can tell you that the index dates shown by Google are accurate but is not the case with the Cache date sometimes as the date shown in the Cache and the copy shown in the cache don't match many times but the index dates are accurate. Send me a private message with the actual URLs under discussion and I will be able to comment with more clarity.
Best,

Thank you for your response Devanur Rafi, but the "good" site doesn't have problems getting indexed.
Actually all posts on the "good" site are indexed the very same day they are published.My question was more about the indexing date shown in Google search results
How come, for a post from the "bad" site, Google is displaying an indexing date previous to the actual date the post was published on that site?!
And how come this date is exactly the same as the date Google says it indexed the post from the "good" site?

Hi Sorina,
This is a common thing and it all depends on a site's crawlability (how easy is it to crawl for the bot) and crawl frequency for that site. Google would have picked up that post first on the bad site and then from the good site. However, just because one or two posts were picked up late does not mean that the good site is not crawler friendly. It also depends on how far the resource is from the root. Let us take an example:
A page on a good site: abc.com/folder1/folder2/folder3/page.html
Now a bad site copies that page: xyz.com/page.html
In this case, Google might first pickup the copied page from the bad site as it is just a click away from the root which is not the case with the good site where the page is nested deep inside multiple folders.
You can also give the way back machine (archive.org) a try to find which website published the post first. Sometimes this might work out pretty well. You can also try to look at the cache dates of the posts on both the sites in Google to get some info in this regard.
Hope those help. I wish you good luck.
Best,
Devanur Rafi.

Google Cache
So, when I gain a link I always check to see if the page that is linking is in the Google cache. I've noticed recently that more and more pages are actually not showing up in Google's cache, yet still appear in search results. I did read an article from someone whoo works at Google a few weeks back that there is sometimes an error with the cache and occasionally the cache will not display. This week, my own website isn't showing up in the cache yet I'm still ranking in SERP's. I'm not worried about it, mostly whitehat, but has there been any indication that Google are phasing out the ability to check cache's of websites?

How long for google to de-index old pages on my site?
I launched my redesigned website 4 days ago. I submitted a new site map, as well as submitted it to index in search console (google webmasters). I see that when I google my site, My new open graph settings are coming up correct. Still, a lot of my old site pages are definitely still indexed within google. How long will it take for google to drop off or "de-index" my old pages? Due to the way I restructured my website, a lot of the items are no longer available on my site. This is on purpose. I'm a graphic designer, and with the new change, I removed many old portfolio items, as well as any references to web design since I will no longer offering that service. My site is the following:

Anyone experience google penalties for full-screen pop-ups?
Although we always recommend against onload pop-ups for clients, (we feel the effect the user experience) we do have a few clients that insist on them. I was reading this article the other day https://searchenginewatch.com/2016/05/17/how-do-i-make-sure-my-site-is-mobile-friendly/ which lead me to https://support.google.com/webmasters/answer/6101188 and I'm happy to see that Google is going to consider these types of content a downgrade when it comes to rank. My question is 2 fold: Has anyone experienced a drop in organic traffic on mobile due to this update? and do you think this will include user triggered content like photo galleries, bookings, email sign ups? We haven't noticed any drops yet but it is something we will be keeping a close eye on in the next little while. Let's hear what the community has to say 🙂

Homepage Index vs Home vs Default?
Should your home page be www.yoursite.com/index.htm or home.htm or default.htm on an apache server? Someone asked me this, and I have no idea. On our wordpress site, I have never even seen this come up, but according to my friend, every homepage HAS to be one of those three. So my question is which one is best for an apache server site AND does it actually have to be one of those three? Thanks, Ruben

Proper Way To Submit A Reconsideration Request To Google
Hello, In previous posts, I was speaking about how we were penalized by Google for unnatural links. Basically 50,000 our of our 58,000 links were coming from 4-5 sites with the same exact anchor text and img alt tags. This obviously was causing our issues. Needless to say, I wen through the complete link profile to determine that all of the links besides this were of natrural origins. My question here is what is the accepted protocol of submitting a reinclusion request; For example, how long should it be? Should I disclose that I was in fact using paid links, and now that I removed (or at least nofollowed) them? I want to make sure that the request as good as it should so I can get our rankings up in a timely manner. Also, how long until the request is typically aknowledged? Thanks

How do I get the expanded results in a Google search?
I notice for certain site (ex: mint.com) that when I search, the top result has a very detailed view with options to click to different subsections of the site. However for my site, even though we're consistently the top result for our branded terms, the result is still only a single line item. How do I adjust this?
