Would you rate-control Googlebot? How much crawling is too much crawling?
-
One of our sites is very large - over 500M pages. Google has indexed 1/8th of the site - and they tend to crawl between 800k and 1M pages per day.
A few times a year, Google will significantly increase their crawl rate - overnight hitting 2M pages per day or more. This creates big problems for us, because at 1M pages per day Google is consuming 70% of our API capacity, and the API overall is at 90% capacity. At 2M pages per day, 20% of our page requests are 500 errors.
I've lobbied for an investment / overhaul of the API configuration to allow for more Google bandwidth without compromising user experience. My tech team counters that it's a wasted investment - as Google will crawl to our capacity whatever that capacity is.
Questions to Enterprise SEOs:
*Is there any validity to the tech team's claim? I thought Google's crawl rate was based on a combination of PageRank and the frequency of page updates. This indicates there is some upper limit - which we perhaps haven't reached - but which would stabilize once reached.
*We've asked Google to rate-limit our crawl rate in the past. Is that harmful? I've always looked at a robust crawl rate as a good problem to have.
- Is 1.5M Googlebot API calls a day desirable, or something any reasonable Enterprise SEO would seek to throttle back?
*What about setting a longer refresh rate in the sitemaps? Would that reduce the daily crawl demand? We could set increase it to a month, but at 500M pages Google could still have a ball at the 2M pages/day rate.
Thanks

I agree with Matt that there can probably be a reduction of pages, but that aside, how much of an issue this is comes down to what pages aren't being indexed. It's hard to advise without the site, are you able to share the domain? If the site has been around for a long time, that seems a low level of indexation. Is this a site where the age of the content matters? For example Craigslist?

Thanks for your response. I get where you're going with that. (Ecomm store gone bad.) It's not actually an Ecomm FWIW. And I do restrict parameters - the list is about a page and a half long. It's a legitimately large site.
You're correct - I don't want Google to crawl the full 500M. But I do want them to crawl 100M. At the current crawl rate we limit them to, it's going to take Google more than 3 months to get to each page a single time. I'd actually like to let them crawl 3M pages a day. Is that an insane amount of Googlebot bandwidth? Does anyone else have a similar situation?
-
Gosh, that's a HUGE site. Are you having Google crawl parameter pages with that? If so, that's a bigger issue.
I can't imagine the crawl issues with 500M pages. A site:amazon.com search only returns 200M. Ebay.com returns 800M so your site is somewhere in between these two? (I understand both probably have a lot more - but not returning as indexed.)
You always WANT a full site crawl - but your techs do have a point. Unless there's an absolutely necessary reason to have 500M indexed pages, I'd also seek to cut that to what you want indexed. That sounds like a nightmare ecommerce store gone bad.

How Much Domain Age Matter In Ranking?
I am very confused about domain age. I read many articles about domain age, some experts say domain age does matter in ranking and some experts say it doesn't matter in the ranking. Kindly guide me about domain age.

Will Reduced Bounce Rate, Increased Pages/Session, Increased Session Duration-RESULT IN BETTER RANKING?
Our relaunched website has a much lower bounce rate (66% before, now 58%) increased pages per session (1.89 before, now 3.47) and increased session duration (1:33 before, now 3:47). The relaunch was December 20th. Should these improvements result in an improvement in Google rank? How about in MOZ authority? We have not significantly changed the content of the site but the UX has been greatly improved. Thanks, Alan

Googlebot being redirected but not users?
Hi, We seem to have a slightly odd issue. We noticed that a number of our location category pages were slipping off 1 page, and onto page 2 in our niche. On inspection, we noticed that our Arizona page had started ranking in place of a number of other location pages - Cali, Idaho, NJ etc. Weirdly, the pages they had replaced were no longer indexed, and would remain so, despite being fetched, tweeted etc. One test was to see when the dropped out pages had been last crawled, or at least cached. When conducting the 'cache:domain.com/category/location' on these pages, we were getting 301 redirected to, you guessed it, the Arizona page. Very odd. However, the dropped out pages were serving 200 OK when run through header checker tools, screaming frog etc. On the face of it, it would seem Googlebot is getting redirected when it is hitting a number of our key location pages, but users are not. Has anyone experienced anything like this? The theming of the pages are quite different in terms of content, meta etc. Thanks.

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

Crawled page count in Search console
Hi Guys, I'm working on a project (premium-hookahs.nl) where I stumble upon a situation I can’t address. Attached is a screenshot of the crawled pages in Search Console. History: Doing to technical difficulties this webshop didn’t always no index filterpages resulting in thousands of duplicated pages. In reality this webshops has less than 1000 individual pages. At this point we took the following steps to result this: Noindex filterpages. Exclude those filterspages in Search Console and robots.txt. Canonical the filterpages to the relevant categoriepages. This however didn’t result in Google crawling less pages. Although the implementation wasn’t always sound (technical problems during updates) I’m sure this setup has been the same for the last two weeks. Personally I expected a drop of crawled pages but they are still sky high. Can’t imagine Google visits this site 40 times a day. To complicate the situation: We’re running an experiment to gain positions on around 250 long term searches. A few filters will be indexed (size, color, number of hoses and flavors) and three of them can be combined. This results in around 250 extra pages. Meta titles, descriptions, h1 and texts are unique as well. Questions: - Excluding in robots.txt should result in Google not crawling those pages right? - Is this number of crawled pages normal for a website with around 1000 unique pages? - What am I missing?

Can't crawl website with Screaming frog... what is wrong?
Hello all - I've just been trying to crawl a site with Screaming Frog and can't get beyond the homepage - have done the usual stuff (turn off JS and so on) and no problems there with nav and so on- the site's other pages have indexed in Google btw. Now I'm wondering whether there's a problem with this robots.txt file, which I think may be auto-generated by Joomla (I'm not familiar with Joomla...) - are there any issues here? [just checked... and there isn't!] If the Joomla site is installed within a folder such as at e.g. www.example.com/joomla/ the robots.txt file MUST be moved to the site root at e.g. www.example.com/robots.txt AND the joomla folder name MUST be prefixed to the disallowed path, e.g. the Disallow rule for the /administrator/ folder MUST be changed to read Disallow: /joomla/administrator/ For more information about the robots.txt standard, see: http://www.robotstxt.org/orig.html For syntax checking, see: http://tool.motoricerca.info/robots-checker.phtml User-agent: *

Googlebot on paywall made with cookies and local storage
My question is about paywalls made with cookies and local storage. We are changing a website with free content to a open paywall with a 5 article view weekly limit. The paywall is made to work with cookies and local storage. The article views are stored to local storage but you have to have your cookies enabled so that you can read the free articles. If you don't have cookies enable we would pass an error page (otherwise the paywall would be easy to bypass). Can you say how this affects SEO? We would still like that Google would index all article pages that it does now. Would it be cloaking if we treated Googlebot differently so that when it does not have cookies enabled, it would still be able to index the page?
