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.

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

How do I know if I am correctly solving an uppercase url issue that may be affecting Googlebot?
We have a large e-commerce site (10k+ SKUs). https://www.flagandbanner.com. As I have begun analyzing how to improve it I have discovered that we have thousands of urls that have uppercase characters. For instance: https://www.flagandbanner.com/Products/patriotic-paper-lanterns-string-lights.asp. This is inconsistently applied throughout the site. I directed our website vendor to fix the issue and they placed 301 redirects via a rule to the web.config file. Any url that contains an uppercase character now displays as a lowercase. However, as I use screaming frog to monitor our site, I see all these 301 redirects--thousands of them. The XML sitemap still shows the the uppercase versions. We have had indexing issues as well. So I'm wondering what is the most effective way to make sure that I'm not placing an extra burden on Googlebot when they index our site? Should I have just not cared about the uppercase issue and let it alone?

Lazy Loading of Blog Posts and Crawl Depths
Hi Moz Fans, We are looking at our blog and improving the content as much as we can for SEO purposes, but we have hit a bit of a blank in terms of lazy loading implications and issues with crawl depths. We introduced lazy loading onto the blog home page to increase site speed initially and it works well with infinite scroll, but we were wondering whether this would cause any issues regarding SEO. A lot of the resources online seem to be conflicting and some are very outdated, so some clarification on what is best in terms of lazy loading and crawl depths for blogs, would be fantastic! I hope someone can help and give us some up to date insights - If you need anymore information, I'll reply ASAP

Mobile Googlebot vs Desktop Googlebot - GWT reports - Crawl errors
Hi Everyone, I have a very specific SEO question. I am doing a site audit and one of the crawl reports is showing tons of 404's for the "smartphone" bot and with very recent crawl dates. If our website is responsive, and we do not have a mobile version of the website I do not understand why the desktop report version has tons of 404's and yet the smartphone does not. I think I am not understanding something conceptually. I think it has something to do with this little message in the Mobile crawl report. "Errors that occurred only when your site was crawled by Googlebot (errors didn't appear for desktop)." If I understand correctly, the "smartphone" report will only show URL's that are not on the desktop report. Is this correct?

How much does dirty html/css etc impact SEO?
Good Morning! I have been trying to clean up this website and half the time I can't even edit our content without breaking the WYSIWYG Editor. Which leads me to the next question. How much, if at all, is this impacting our SEO. To my knowledge this isn't directly causing any broken pages for the viewer, but still, it certainly concerns me. I found this post on Moz from last year: http://moz.com/community/q/how-much-impact-does-bad-html-coding-really-have-on-seo We have a slightly different set of code problems but still wanted to revisit this question and see if anything has changed. I also can't imagine that all this broken/extra code is helping our page load properly. Thanks everybody!

Google Analytics: how to filter out pages with low bounce rate?
Hello here, I am trying to find out how I can filter out pages in Google Analytics according to their bounce rate. The way I am doing now is the following: 1. I am working inside the Content > Site Content > Landing Pages report 2. Once there, I click the "advanced" link on the right of the filter field. 3. Once there, I define to "include" "Bounce Rate" "Greater than" "0.50" which should show me which pages have a bounce rate higher of 0.50%.... instead I get the following warning on the graph: "Search constraints on metrics can not be applied to this graph" I am afraid I am using the wrong approach... any ideas are very welcome! Thank you in advance.

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?
