Crawl Stats Decline After Site Launch (Pages Crawled Per Day, KB Downloaded Per Day)
-
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.
User-agent: ShopWiki Disallow: / User-agent: deepcrawl Disallow: / User-agent: Speedy Disallow: / User-agent: SLI_Systems_Indexer Disallow: / User-agent: Yandex Disallow: / User-agent: MJ12bot Disallow: / User-agent: BrightEdge Crawler/1.0 (crawler@brightedge.com) Disallow: / User-agent: * Crawl-delay: 5 Disallow: /cart/ Disallow: /compare/ ```[fSAOL0](https://ibb.co/fSAOL0)

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.

XML sitemap generator only crawling 20% of my site
Hi guys, I am trying to submit the most recent XML sitemap but the sitemap generator tools are only crawling about 20% of my site. The site carries around 150 pages and only 37 show up on tools like xml-sitemaps.com. My goal is to get all the important URLs we care about into the XML sitemap. How should I go about this? Thanks

Why does Google rank a product page rather than a category page?
Hi, everybody In the Moz ranking tool for one of our client's (the client sells sport equipment) account, there is a trend where more and more of their landing pages are product pages instead of category pages. The optimal landing page for the term "sleeping bag" is of course the sleeping bag category page, but Google is sending them to a product page for a specific sleeping bag.. What could be the critical factors that makes the product page more relevant than the category page as the landing page?

ScreamingFrog won't crawl my site.
Hey guys, My site is Netspiren.dk and when I use a tool like Screaming Frog or Integrity, it only crawls my homepage and menu's - not product-pages. Examples
Intermediate & Advanced SEO | | FrederikTrovatten22
A menu: http://www.netspiren.dk/pl/Helse-Kosttilskud-Blandingsolie_57699.aspx
A product: http://www.netspiren.dk/pi/All-Omega-3-6-9-180-kapsler_1412956_57699.aspx Is it because the products are being loaded in Javascript?
What's your recommendation? All best,

Merging Sites: Will redirecting the old homepage to an internal page on the new site cause issues?
I've ended up with two sites which have similar content (but not duplicate) and target similar keywords, rather than trying to maintain two sites I would like to merge the sites together. The old site is more of a traditional niche site and targets a particular set of keywords on its homepage, the new site is more of an authority site with a magazine type homepage and targets the same set of keywords from an internal page. My question is: Should I redirect the old site's homepage to the relevant internal page on the new website...
Intermediate & Advanced SEO | | lara_dar
...or should I redirect the old site's homepage to the new site's homepage? (the old site's homepage backlinks are a mixture of partial match keyword anchor text, naked URLs and branded anchor text) I am in two minds (a & b!) (a) Redirecting to the internal page would be great for ranking as there are some decent backlinks and the content is similar (b) But usually when you do a 301 redirect the homepage usually directs to the new homepage and some of the old site's links are related to the domain rather than the keyword (e.g. http://www.site.com) and some people will be looking for the site's homepage. What do you think? Your help is much appreciated (and hope this makes sense...!)0 -
Best possible linking on site with 100K indexed pages
Hello All, First of all I would like to thank everybody here for sharing such great knowledge with such amazing and heartfelt passion.It really is good to see. Thank you. My story / question: I recently sold a site with more than 100k pages indexed in Google. I was allowed to keep links on the site.These links being actual anchor text links on both the home page as well on the 100k news articles. On top of that, my site syndicates its rss feed (Just links and titles, no content) to this page. However, the new owner made a mess, and now the site could possibly be seen as bad linking to my site. Google tells me within webmasters that this particular site gives me more than 400K backlinks. I have NEVER received one single notice from Google that I have bad links. That first. But, I was worried that this page could have been the reason why MY site tanked as bad as it did. It's the only source linking so massive to me. Just a few days ago, I got in contact with the new site owner. And he has taken my offer to help him 'better' his site. Although getting the site up to date for him is my main purpose, since I am there, I will also put effort in to optimizing the links back to my site. My question: What would be the best to do for my 'most SEO gain' out of this? The site is a news paper type of site, catering for news within the exact niche my site is trying to rank. Difference being, his is a news site, mine is not. It is commercial. Once I fix his site, there will be regular news updates all within the niche we both are in. Regularly as in several times per day. It's news. In the niche. Should I leave my rss feed in the side bars of all the content? Should I leave an achor text link on the sidebar (on all news etc.) If so: there can be just one keyword... 407K pages linking with just 1 kw?? Should I keep it to just one link on the home page? I would love to hear what you guys think. (My domain is from 2001. Like a quality wine. However, still tanked like a submarine.) ALL SEO reports I got here are now Grade A. The site is finally fully optimized. Truly nice to have that confirmation. Now I hope someone will be able to tell me what is best to do, in order to get the most SEO gain out of this for my site. Thank you.

Dynamic pages - ecommerce product pages
Hi guys, Before I dive into my question, let me give you some background.. I manage an ecommerce site and we're got thousands of product pages. The pages contain dynamic blocks and information in these blocks are fed by another system. So in a nutshell, our product team enters the data in a software and boom, the information is generated in these page blocks. But that's not all, these pages then redirect to a duplicate version with a custom URL. This is cached and this is what the end user sees. This was done to speed up load, rather than the system generate a dynamic page on the fly, the cache page is loaded and the user sees it super fast. Another benefit happened as well, after going live with the cached pages, they started getting indexed and ranking in Google. The problem is that, the redirect to the duplicate cached page isn't a permanent one, it's a meta refresh, a 302 that happens in a second. So yeah, I've got 302s kicking about. The development team can set up 301 but then there won't be any caching, pages will just load dynamically. Google records pages that are cached but does it cache a dynamic page though? Without a cached page, I'm wondering if I would drop in traffic. The view source might just show a list of dynamic blocks, no content! How would you tackle this? I've already setup canonical tags on the cached pages but removing cache.. Thanks

Splitting a Site into Two Sites for SEO Purposes
I have a client that owns a business that really could be easily divided into two separate business in terms of SEO. Right now his web site covers both divisions of his business. He gets about 5500 visitors a month. The majority go to one part of his business and around 600 each month go to the other. So about 11% I'm considering breaking off this 11% and putting it on an entirely different domain name. I think I could rank better for this 11%. The site would only be SEO'd for this particular division of the company. The keywords would not be in competition with each other. I would of course link the two web sites and watch that I don't run into any duplicate content issues. I worry about placing the redirects from the pages that I remove to the new pages. I know Google is not a fan of redirects. Then I also worry about the eventual drop in traffic to the main site now. How big of a factor is traffic in rankings? Other challenges include that the business services 4 major metropolitan areas. Would you do this? Have you done this? How did it work? Any suggestions?
