      Hi all,

      I have been looking into this for about a month and haven't been able to figure out what is going on with this situation. We recently did a website re-design and moved from a separate mobile site to responsive. After the launch, I immediately noticed a decline in pages crawled per day and KB downloaded per day in the crawl stats. I expected the opposite to happen as I figured Google would be crawling more pages for a while to figure out the new site. There was also an increase in time spent downloading a page. This has went back down but the pages crawled has never went back up. Some notes about the re-design:

      • URLs did not change
      • Mobile URLs were redirected
      • Images were moved from a subdomain (images.sitename.com) to Amazon S3
      • Had an immediate decline in both organic and paid traffic (roughly 20-30% for each channel)

      I have not been able to find any glaring issues in search console as indexation looks good, no spike in 404s, or mobile usability issues. Just wondering if anyone has an idea or insight into what caused the drop in pages crawled? Here is the robots.txt and attaching a photo of the crawl stats.

        Yea that's definitely tricky. I'm assuming you haven't taken out any load balancing that was previously in place between desktop and m. meaning your server is struggling a lot more? The Page Speed Insights tool can be good info but if possible I'd have a look at that user experience index to get an idea of how other users are experiencing the site.

        A next port of call could be your server logs? Do you have any other subdomains which are performing differently in search console?

        In terms of getting Google to crawl more, unfortunately at this point my instinct would be to keep trying to optimise the site to make it as crawl-friendly as possible and wait for Google to start crawling more. It does look like the original spike in time spent downloading has subsided a bit but it's still higher than it was. Without doing the maths, given that pages crawled and kilobytes downloaded have dropped, the level of slowdown may have persisted and the drop in that graph could have been caused by Google easing back. I'd keep working on making the site as efficient and consistent as possible and try to get that line tracking lower as an immediate tactic.

          Hi Robin,

          Thanks a lot for the reply. A lot of good information there.

          • The crawl delay has been on the site as long as I have known so it was left in place just to minimize changes
          • Have not changed any of the settings in Search Console. It has remained at "Let Google optimize for my site"
          • Have not received the notification for mobile first indexing
          • The redirects were one to one for the mobile site. I do not believe there are any redirect chains from those.
          • The desktop pages remained roughly the same size but on a mobile device, pages are slightly heavier compared to the sepatate m dot site. The separate m dot site had a lot of content stripped out and was pretty bare to be fast. We introduced more image compression than we have ever done and also deferred image loading to make the user experience as fast as possible. The site scores in the 90s on Google's page speed insights tool.
          • Yes, resizing based on viewport. Content is basically the same between devices. We have some information in accordions on product detail pages on and show fewer products on the grids on mobile.
          • They are not the same images files but they are actually smaller than they were previously as we were not compressing them and using different sizes in different locations to minimize page weight.

          I definitely lean towards it being performance related as in the crawl stats there seems to be a correlation between time spent downloading a page and the other two stats. I just wonder how you get Google to start crawling more once the performance is fixed or if they will figure it out.

            Hi there, thanks for posting!

            Sounds like an interesting one, some questions that come to mind which I'd just like to run through to make sure we're not missing anything;

            • Why do you have Crawl-delay set for all user agents? Officially it's not something Google supports but the reason for that could be the cause of this
            • Have you changed any settings in search console? There is a slider for how often you want Google to crawl a site
            • Have you had the Search Console notification that you're now on the mobile-first index?
            • When you redirected the mobile site, was it all one-to-one redirects? Is there any possibility you've introduced redirect chains?
            • After the redesign - are the pages now significantly bigger (in terms of amount of data needed to fully load the page)? Are there any very large assets that are now on every page?
            • When you say responsive, is it resizing based on viewport? How much duplication has been added to the page? Is there a bunch of content that is there for mobile but not loaded unless viewed from mobile (and vice versa)?
            • When you moved the images, were they the same exact image files or might they now be the full-size image files?

            This is just first blush so I could be off the mark but those graphs suggest to me that Google is having to work harder to crawl your pages and, as a result, is throttling the amount of time spent on your site. If the redesign or switch to responsive involved making the pages significantly "heavier" where that could be additional JavaScript, bigger images, more content etc. that could cause that effect. If you've got any sitespeed benchmarking in place you could have a look at that to see whether things have changed. Google also uses pagespeed as a ranking factor so that could explain the traffic drop.

            The other thing to bear in mind is that combining the mobile and desktop sites was essentially a migration, particularly if you were on the mobile-first index. It may be that the traffic dip is less related to the crawl rate, but I understand why we'd make the connection there.

              Is it good or bad to add noindex for empty pages, which will get content dynamically after some days

              We have followers, following, friends, etc pages for each user who creates account on our website. so when new user sign up, he may have 0 followers, 0 following and 0 friends, but over period of time he can get those lists go up. we have different pages for followers, following and friends which are allowed for google to index. When user don't have any followers/following/friends, those pages looks empty and we get issue of duplicate content and description too short. so is it better that we add  noindex for those pages temporarily and remove noindex tag when there are at least 2 or more people on those pages. What are side effects of adding noindex when there is no data on those page or benefits of it?

              URL structure - Page Path vs No Page Path

              We are currently re building our URL structure for eccomerce websites. We have seen a lot of site removing the page path on product pages e.g. https://www.theiconic.co.nz/liberty-beach-blossom-shirt-680193.html versus what would normally be https://www.theiconic.co.nz/womens-clothing-tops/liberty-beach-blossom-shirt-680193.html Should we be removing the site page path for a product page to keep the url shorter or should we keep it? I can see that we would loose the hierarchy juice to a product page but not sure what is the right thing to do.

              If a page ranks in the wrong country and is redirected, does that problem pass to the new page?

              Hi guys, I'm having a weird problem: A new multilingual site was launched about 2 months ago. It has correct hreflang tags and Geo targetting in GSC for every language version. We redirected some relevant pages (with good PA) from another website of our client's. It turned out that the pages were not ranking in the correct country markets (for example, the en-gb page ranking in the USA). The pages from our site seem to have the same problem. Do you think they inherited it due to the redirects? Is it possible that Google will sort things out over some time, given the fact that the new pages have correct hreflangs? Is there stuff we could do to help ranking in the correct country markets?

              Category Page as Shopping Aggregator Page

              Hi, I have been reviewing the info from Google on structured data for products and started to ponder. 
              https://developers.google.com/search/docs/data-types/products Here is the scenario.
              You have a Category Page and it lists 8 products, each products shows an image, price and review rating. As the individual products pages are already marked up they display Rich Snippets in the serps. 
              I wonder how do we get the rich snippets for the category page. Now Google suggest a markup for shopping aggregator pages that lists a single product, along with information about different sellers offering that product but nothing for categories. My ponder is this, Can we use the shopping aggregator markup for category pages to achieve the coveted rich results (from and to price, average reviews)? Keen to hear from anyone who has had any thoughts on the matter or had already tried this.

              Google Adsbot crawling order confirmation pages?

              Hi, We have had roughly 1000+ requests per 24 hours from Google-adsbot to our confirmation pages. This generates an error as the confirmation page cannot be viewed after closing or by anyone who didn't complete the order. How is google-adsbot finding pages to crawl that are not linked to anywhere on the site, in the sitemap or linked to anywhere else? Is there any harm in a google crawler receiving a higher percentage of errors - even though the pages are not supposed to be requested. Is there anything we can do to prevent the errors for the benefit of our network team and what are the possible risks of any measures we can take? This bot seems to be for evaluating the quality of landing pages used in for Adwords so why is it trying to access confirmation pages when they have not been set for any of our adverts? We included "Disallow: /confirmation" in the robots.txt but it has continued to request these pages, generating a 403 page and an error in the log files so it seems Adsbot doesn't follow robots.txt. Thanks in advance for any help, Sam

              Splitting One Site Into Two Sites Best Practices Needed

              Okay, working with a large site that, for business reasons beyond organic search, wants to split an existing site in two. So, the old domain name stays and a new one is born with some of the content from the old site, along with some new content of its own. The general idea, for more than just search reasons, is that it makes both the old site and new sites more purely about their respective subject matter.  The existing content on the old site that is becoming part of the new site will be 301'd to the new site's domain. So, the old site will have a lot of 301s and links to the new site. No links coming back from the new site to the old site anticipated at this time. Would like any and all insights into any potential pitfalls and best practices for this to come off as well as it can under the circumstances. For instance, should all those links from the old site to the new site be nofollowed, kind of like a non-editorial link to an affiliate or advertiser? Is there weirdness for Google in 301ing to a new domain from some, but not all, content of the old site. Would you individually submit requests to remove from index for the hundreds and hundreds of old site pages moving to the new site or just figure that the 301 will eventually take care of that? Is there substantial organic search risk of any kind to the old site, beyond the obvious of just not having those pages to produce any more? Anything else? Any ideas about how long the new site can expect to wander the wilderness of no organic search traffic? The old site has a 45 domain authority. Thanks!

              Domain Authority: 23, Page Authority: 33, Can My Site Still Rank?

              Greetings: Our New York City commercial real estate site is www.nyc-officespace-leader.com. Key MOZ metric are as follows: Domain Authority: 23
              Page Authority: 33
              28 Root Domains linking to the site
              179 Total Links. In the last six months domain authority, page authority, domains linking to the site have declined. We have focused on removing duplicate content and low quality links which may have had a negative impact on the above metrics. Our ranking has dropped greatly in the last two months. Could it be due to the above metrics? These numbers seem pretty bad. How can I reverse without engaging in any black hat behavior that could work against me in the future? Ideas?
              Thanks, Alan Rosinsky

              NOINDEX listing pages: Page 2, Page 3... etc?

              Would it be beneficial to NOINDEX category listing pages except for the first page.  For example on this site: http://flyawaysimulation.com/downloads/101/fsx-missions/ Has lots of pages such as Page 2, Page 3, Page 4... etc: http://www.google.com/search?q=site%3Aflyawaysimulation.com+fsx+missions Would there be any SEO benefit of NOINDEX on these pages?  Of course, FOLLOW is default, so links would still be followed and juice applied. Your thoughts and suggestions are much appreciated.
