Googlebot Crawl Rate causing site slowdown
-
I am hearing from my IT department that Googlebot is causing as massive slowdown/crash our site. We get 3.5 to 4 million pageviews a month and add 70-100 new articles on the website each day. We provide daily stock research and marke analysis, so its all high quality relevant content. Here are the crawl stats from WMT:
I have not worked with a lot of high volume high traffic sites before, but these crawl stats do not seem to be out of line. My team is getting pressure from the sysadmins to slow down the crawl rate, or block some or all of the site from GoogleBot.
Do these crawl stats seem in line with sites? Would slowing down crawl rates have a big effect on rankings?
Thanks

Similar to Michael, my IT team is saying Googlebot is causing performance issues - specifically during peak hours.
It was suggested that we consider using apache re-write rules to serve Googlebot a 503 during our peak hours to limit the impact. I found the stackoverflow thread (link below) in which John Muller seems to suggest this approach, but has anyone tried this?

Blocking googlebot is a quick and easy way to disappear from the Index. Not an option if you want Google to rank your site.
For smaller sites or ones with limited technologies, I sometimes recommend using a crawl-delay directive in robots.txt

But I agree with both Shane and Zachary, this doesn't seem like the long term answer to your problems. Your crawl stats don't seem out of line for a site of your size, and perhaps a better hardware configuration could help things out.
With 70 new articles each day, I'd want Google crawling my site as much as they pleased.

whatever Google's default is in GWT - It sets it for you.
You can change it, but it is not reccomended unless for a specific reason (such as Michael Lewis's specific scenario) even though, I am not completely sold that Gbot is what is causing the "dealbreaking" overhead.

what is the ideal setting on the crawler. i have been wondering about this for some time.

Hi,
Your admins saying that, is like someone saying "we need to shut the site down, we are getting to much traffic!" Common sys-admin response (fix it somewhere else)
4GB a day downloaded, is alot of Bot traffic, but it appears you are a "real time" site, that is probably actually helped and maybe even reliant on your high crawl rate....
I would upgrade hardware - or even look into some kind of off site cloud redundancy for failover (Hybrid)
I highly doubt that 4GB a day, is a "dealbreaker",but of course that is just based off the one image, and your admins probably have resource monitors - Maybe Varnish is an answer for static content to help lighten load???? Or CDN for file hosting to lighten bandwidth load?

We are hosting the site on our own hardware at a big colo. I know that we are upgrading servers but they will not be online until the end of July.
Thanks!

I wouldn't slow the crawl rate. A high crawl rate is good so that Google can keep their index of your website current.
The better solution is to reconsider your hardware and networking setup. Do you know how you are being hosted? From my own experience with a website of that size, a load balancer on two decent dedicated servers should handle the load without problems. Google crawling your pages shouldn't create noticeable overhead on the right setup.

Why are these blackhat sites so successful?
Here's an interesting conundrum. Here are three sites with their respective ranking for "dental implants [city]:" http://dentalimplantsvaughan.ca - 9 (on google.ca) http://dentalimplantsinhonoluluhi.com - 2 (on google.com) http://dentalimplantssurreybc.ca - 7 (on google.ca) These markets are not particularly competitive, however, all of these sites suffer from: Duplicate content, both internally and across sites (all of this company's implant sites have the same exact content, minus the bio pages and the local modifier). Average speed score. No structured data No links And these sites are ranking relatively quickly. The Vaughan site went live 3 months ago. But, what's boggling my mind is that they rank on the first page at all. It seems they're doing the exact opposite of what you're supposed to do, yet they rank relatively well.

Is it problematic for Google when the site of a subdomain is on a different host than the site of the primary domain?
The Website on the subdomain runs on a different server (host) than the site on the main domain.

Site structure headache
Hello all, I'm struggling to get to grips with a websites site structure. I appreciate that quality content is key etc, and the more content the better, but then I have issues with regards to doorway pages. For example im now starting to develop a lot of ecommerce websites and want to promote this service. should we have pages that detail all of the ins and outs of ecommerce - or should we simplify it to a couple of pages. what is best practice? Also isn't a content hub similar to having doorway pages? let me know what you think! William

Site maps, Is there any benefit?
I have a relatively simple and small site (60 pages). All of it is crawlable and there is nothing I want non follow. So, is there any real benefit to a sitemap since Google can get to all the site anyway? Do they give the site more credence or something because it's there? I guess as an aside, are there any favorite sites that will generate a site map? Thanks!

Replacing a site map
We are in the process of changing our folder/url structure. Currently we have about 5 sitemaps submitted to Google. How is it best to deal with these site maps in terms of either (a) replacing the old URLs with the new ones in the site map and (b) what affect should we have if we removed the site map submission from the Google Webmaster Tools console. Basically we have in the region of 20,000 urls to redirect to the new format, and to update in the site map.

Why does my site have a PageRank of 0?
My site (www.onemedical.com) has a PageRank of 0, and I can't figure out why. We did a major site update about a year ago, and moved the site from .md to .com about 9 months ago. We are crawled by Google and rank on the first page for many of our top keywords. We have a MozRank of 4.59. I figured this is something that would just take time to work out of the system, but nothing seems to change while we patiently wait. One more thing to note - when a user comes to the homepage (city selector) and selects their region they will then be cookied and directed to their relevant city site on subsequent visits. But even our city-specific pages (ie www.onemedical.com/sf) have pageranks of 0. My management team keeps asking me about this and I suspect there is something silly that we keep overlooking...but for the life of me, can't figure it out. Any help would be appreciated.
