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.

What happens to crawled URLs subsequently blocked by robots.txt?
We have a very large store with 278,146 individual product pages. Since these are all various sizes and packaging quantities of less than 200 product categories my feeling is that Google would be better off making sure our category pages are indexed. I would like to block all product pages via robots.txt until we are sure all category pages are indexed, then unblock them. Our product pages rarely change, no ratings or product reviews so there is little reason for a search engine to revisit a product page. The sales team is afraid blocking a previously indexed product page will result in in it being removed from the Google index and would prefer to submit the categories by hand, 10 per day via requested crawling. Which is the better practice?

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

Does content revealed by a 'show more' button get crawled by Google?
I have a div on my website with around 500 words of unique content in, automatically when the page is first visited the div has a fixed height of 100px, showing a couple of hundred words and fading out to white, with a show more button, which when clicked, increases the height to show the full content. My question is, does Google crawl the content in that div when it renders the page? Or disregard it? Its all in the source code. Or worse, do they consider this cloaking or hidden content? It is only there to make the site more useable for customers, so i don't want to get penalised for it. Cheers

Using "nofollow" internally can help with crawl budget?
Hello everyone. I was reading this article on semrush.com, published the last year, and I'd like to know your thoughts about it: https://www.semrush.com/blog/does-google-crawl-relnofollow-at-all/ Is that really the case? I thought that Google crawls and "follows" nofollowed tagged links even though doesn't pass any PR to the destination link. If instead Google really doesn't crawl internal links tagged as "nofollow", can that really help with crawl budget?

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?

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,

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: *

Could you use a robots.txt file to disalow a duplicate content page from being crawled?
A website has duplicate content pages to make it easier for users to find the information from a couple spots in the site navigation. Site owner would like to keep it this way without hurting SEO. I've thought of using the robots.txt file to disallow search engines from crawling one of the pages. Would you think this is a workable/acceptable solution?
