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.

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

Google crawling different content--ever ok?
Here are a couple of scenarios I'm encountering where Google will crawl different content than my users on initial visit to the site--and which I think should be ok. Of course, it is normally NOT ok, I'm here to find out if Google is flexible enough to allow these situations: 1. My mobile friendly site has users select a city, and then it displays the location options div which includes an explanation for why they may want to have the program use their gps location. The user must choose the gps, the entire city, or he can enter a zip code, or choose a suburb of the city, which then goes to the link chosen. OTOH it is programmed so that if it is a Google bot it doesn't get just a meaningless 'choose further' page, but rather the crawler sees the page of results for the entire city (as you would expect from the url), So basically the program defaults for the entire city results for google bot, but for for the user it first gives him the initial ability to choose gps. 2. A user comes to mysite.com/gps-loc/city/results The site, seeing the literal words 'gps-loc' in the url goes out and fetches the gps for his location and returns results dependent on his location. If Googlebot comes to that url then there is no way the program will return the same results because the program wouldn't be able to get the same long latitude as that user. So, what do you think? Are these scenarios a concern for getting penalized by Google? Thanks, Ted

Why is my Crawl Report Showing Thousands of Pages that Do Not Exist?
Hi, I just downloaded a Crawl Summary Report for a client's website. I am seeing THOUSANDS of duplicate page content errors.

Why are these pages showing up? How do I get rid of them? Are they endangering the health of my site as a whole? Thank you, Jenna <colgroup><col width="1051"></colgroup>

How to prevent Google from crawling our product filter?
Hi All, We have a crawler problem on one of our sites www.sneakerskoopjeonline.nl. On this site, visitors can specify criteria to filter available products. These filters are passed as http/get arguments. The number of possible filter urls is virtually limitless. In order to prevent duplicate content, or an insane amount of pages in the search indices, our software automatically adds noindex, nofollow and noarchive directives to these filter result pages. However, we’re unable to explain to crawlers (Google in particular) to ignore these urls. We’ve already changed the on page filter html to javascript, hoping this would cause the crawler to ignore it. However, it seems that Googlebot executes the javascript and crawls the generated urls anyway. What can we do to prevent Google from crawling all the filter options? Thanks in advance for the help. Kind regards, Gerwin
