June 7th, 2013 Structured Data Drop
-
On June 7th, 2013 our structured data (as reported in GWT) dropped from ~61M items on ~7M pages to ~13.5M items on ~1.5M pages. Since that time those numbers have continued to fall. We made no code changes during this time. I've searched around the web and found a few people pointing to a similar June 7th, 2013 drop in reported structured data.
Can anyone offer any insight beyond speculation? Outside of the June 7th date, what can cause such a dramatic drop in structured data? Thanks in advance.

That's funny Ryan as I just looked at one of our account that I know has structured data and saw the same thing, a dip then a rise.
Sounds like a bug in Google's side, which was my first guess, I only got more interested when I read the forums and people said they also had a drop in rankings. Having looked into it, it sounds like those who got a drop in traffic are likely being impacted by updates around that time which was nothing to do with the data issue.
I'm going to mark the question as resolved but I'll add any details I find out.

Craig,
Actually, our structured data numbers tanked on 6/7 and then bounced back on 6/21 so it isn't an issue anymore. That being said, I'm definitely curious about what happened if you have any ideas.
Thanks for the heads up.

Hey Ryan,
I'm going to look into this for you, so far I've only seen the same articles that you have but I'll ask around and get back to you as soon as I can, just thought I'd drop you a note to let you know your question is being looked at.

Question on URL wording and structure best practices
We're mapping out some URL structures and trying to figure out what would be best for separating folders for articles and videos regarding wording in the folder say: www.site.com/category/article/name-of-article/id#/ ---- www.site.com/category/video/name-of-video/id#/ vs. www.site.com/category/a/name-of-article/id#/ ---- www.site.com/category/v/name-of-video/id#/ Second option came about the ''shorter is better' way of thinking. Downside I see to it is if the link would be copied and pasted somewhere probably would be best for a user to make it clear they are clicking into an article or a video, don't think just an 'a' or a 'v' would be very telling in that scenario. Would it be better for search engines to make it clearer with the whole word in there? Any other pros and cons to each? Not sure what's the best route here.

How long after disallowing Googlebot from crawling a domain until those pages drop out of their index?
We recently had Google crawl a version of the site we that we had thought we had disallowed already. We have corrected the issue of them crawling the site, but pages from that version are still appearing in the search results (the version we want them to not index and serve up is our .us domain which should have been blocked to them). My question is this: How long should I expect that domain (the .us we don't want to appear) to stay in their index after disallowing their bot? Is this a matter of days, weeks, or months?

Google dropping pages from SERPs even though indexed and cached. (Shift over to https suspected.)
Anybody know why pages that have previously been indexed - and that are still present in Google's cache - are now not appearing in Google SERPs? All the usual suspects - noindex, robots, duplication filter, 301s - have been ruled out. We shifted our site over from http to https last week and it appears to have started then, although we have also been playing around with our navigation structure a bit too. Here are a few examples... Example 1: Live URL: https://www.normanrecords.com/records/149002-memory-drawings-there-is-no-perfect-place Cached copy: http://webcache.googleusercontent.com/search?q=cache:https://www.normanrecords.com/records/149002-memory-drawings-there-is-no-perfect-place SERP (1): https://www.google.co.uk/search?q=memory+drawings+there+is+no+perfect+place SERP (2): https://www.google.co.uk/search?q=memory+drawings+there+is+no+perfect+place+site%3Awww.normanrecords.com Example 2: SERP: https://www.google.co.uk/search?q=deaf+center+recount+site%3Awww.normanrecords.com Live URL: https://www.normanrecords.com/records/149001-deaf-center-recount- Cached copy: http://webcache.googleusercontent.com/search?q=cache:https://www.normanrecords.com/records/149001-deaf-center-recount- These are pages that have been linked to from our homepage (Moz PA of 68) prominently for days, are present and correct in our sitemap (https://www.normanrecords.com/catalogue_sitemap.xml), have unique content, have decent on-page optimisation, etc. etc. We moved over to https on 11 Aug. There were some initial wobbles (e.g. 301s from normanrecords.com to www.normanrecords.com got caught up in a nasty loop due to the conflicting 301 from http to https) but these were quickly sorted (i.e. spotted and resolved within minutes). There have been some other changes made to the structure of the site (e.g. a reduction in the navigation options) but nothing I know of that would cause pages to drop like this. For the first example (Memory Drawings) we were ranking on the first page right up until this morning and have been receiving Google traffic for it ever since it was added to the site on 4 Aug. Any help very much appreciated! At the very end of my tether / understanding here... Cheers, Nathon

Panda: Are our ads duplicate content or just structural and not even considered?
We have hundreds and hundreds of pages with similar ads on. We are getting content written for these pages right now and we're removing some pages, but we're wondering how Panda might see the ads which we have across the site? The ads consist of the name of a company and a description and a few other bits. The description is the same on all pages that a company's ad is listed on - and that can be hundreds of pages. You can see some examples here: http://www.agencycentral.co.uk/agencysearch/accounting/skills/indandcomm/financialanalyst.htm http://www.agencycentral.co.uk/agencysearch/accounting/skills/indandcomm/financialaccountant.htm http://www.agencycentral.co.uk/agencysearch/accounting/skills/indandcomm/assistantaccountant.htm What we're wondering is whether Google Panda might be seeing the description of the company as internal duplicate content or just structural and not even considered as part of the Panda algorithm? Or something else? Or wouldn't it be clear in this case? Clearly Panda wouldn't hit duplicate content in nav bards, sidebars etc... but this is in the content area of the page so it did make us wonder. This could make a difference to how we proceed so we appreciate your thoughts. Regards, Phil

URL Structure for "Find A Professional" Page
I've read all the URL structure posts out there, but I'm really undecided and would love a second opinion. Currently, this is how the developer has our professionals directory working: 1. You search by inputting your Zip Code and selecting a category (such as Pool Companies) and we return all professionals within a X-mile radius of that ZIP. This is how the URL's are structured... 1. Main Page: /our-professionals 2. The URL looks like this after a search for "Deck Builders" in ZIP 19033: /our-professionals?zipcode=19033&HidSuppliers=&HiddenSpaces=&HidServices=&HidServices_all=[16]%2C&HidMetroareas=&srchbox= 3. When I click one of the businesses, URL looks like this: viewprofile.php?id=409 I know how to go about doing this, but I'm undecided on the best structure for the URL's. Maybe for results pages do this: find-professionals/deck-builders/philadelphia-pa-19033 And for individual pro's profiles do this: /deck-builders/philadelphia-pa-19033/Billys-Deck-Service Any input on how to best structure this so that we can have a good chance of showing in SERPs for "Deck Builders near New Jersey" and the such, would be much appreciated.

Large amounts of ranking data
Hello all, I am currently conducting some keyword. I need to check a websites rankings for around 1000 keywords. I currently use chrome on a Mac. This presents a problem, because all of the APIs I've seen are for excel on windows. Does anyone have any ideas of how to do this on a Mac & Chrome? Thanks, Chris

Developing a drop down menu: Do I use javascript or pure css?
I am developing a drop down menu and am trying to decide if using javascript instead of just css is worth it. I've done some research on the topic and the opinions seem dated. I know that at one time not using javascript for a drop down menu was important but now less so. Google constantly says that they will not discount the links just because they are not shown until javascript is ran. What I want to know is has anyone discovered from testing that using javascript instead of css for a drop down makes a difference? Note: the links will not be located in an external javascript file.
