Should we use Google's crawl delay setting?
-
We’ve been noticing a huge uptick in Google’s spidering lately, and along with it a notable worsening of render times.
Yesterday, for example, Google spidered our site at a rate of 30:1 (google spider vs. organic traffic.) So in other words, for every organic page request, Google hits the site 30 times.
Our render times have lengthened to an avg. of 2 seconds (and up to 2.5 seconds). Before this renewed interest Google has taken in us we were seeing closer to one second average render times, and often half of that.
A year ago, the ratio of Spider to Organic was between 6:1 and 10:1.
Is requesting a crawl-delay from Googlebot a viable option?
Our goal would be only to reduce Googlebot traffic, and hopefully improve render times and organic traffic.
Thanks,
Trisha

Unfortunately you can't change crawl settings for Google in a robots.txt file, they just ignore it. The best way to rate limit them is using custom Crawl settings in Google Webmaster Tools. (look under Site configuration > Settings)
You also might want to consider using your loadbalancer to direct Google (and other search engines) to a "condomised" group of servers (app, db, cache, search) thereby ensuring your users arent inadvertantly hit by perfomance issues caused by over zealous bot crawling.

We're a publisher, which means that as an industry our normal render times are always at the top of the chart. Ads are notoriously slow to load, and that's how we earn our keep. These results are bad, though, even for publishing.
We're serving millions of uniques a month, on a bank of dedicated servers hosted off site, load balanced, etc.

Server Connection Error when using Google Speed Test Insight and GTMetrix
Hi Guys, Recently got into the issue when testing load speed of my website (https://solvid.co.uk). Occasionally, Google Speed Insights gives me a server connection error which states _"PageSpeed was unable to connect to the server. Ensure that you are using the correct protocol (_http vs https), the page loads in a browser, and is accessible on the public internet." Also, GTMetrix gives me an error as well, which states the following: "An error occurred fetching the page: HTTPS error: SSl connect attempt failed" All of my redirects seem to be set-up correctly as well as the SSL certificate. I've contacted my hosting provider (godaddy), they are saying that everything is fine with the server and the installation. Also, tried in different browsers in incognito mode, still gives me the same error. Until yesterday I haven't had such a problem. I've also attached the error screenshot links. I would really appreciate your help! Dmytro UxchPYR M52iPDf

Soft 404's on a 301 Redirect...Why?
So we launched a site about a month ago. Our old site had an extensive library of health content that went away with the relaunch. We redirected this entire section of the site to the new education materials, but we've yet to see this reflected in the index or in GWT. In fact, we're getting close to 500 soft 404's in GWT. Our development team confirmed for me that the 301 redirect is configured correctly. Is it just a waiting game at this point or is there something I might be missing? Any help is appreciated. Thanks!

How to Remove /feed URLs from Google's Index
Hey everyone, I have an issue with RSS /feed URLs being indexed by Google for some of our Wordpress sites. Have a look at this Google query, and click to show omitted search results. You'll see we have 500+ /feed URLs indexed by Google, for our many category pages/etc. Here is one of the example URLs: http://www.howdesign.com/design-creativity/fonts-typography/letterforms/attachment/gilhelveticatrade/feed/. Based on this content/code of the XML page, it looks like Wordpress is generating these: <generator>http://wordpress.org/?v=3.5.2</generator> Any idea how to get them out of Google's index without 301 redirecting them? We need the Wordpress-generated RSS feeds to work for various uses. My first two thoughts are trying to work with our Development team to see if we can get a "noindex" meta robots tag on the pages, by they are dynamically-generated pages...so I'm not sure if that will be possible. Or, perhaps we can add a "feed" paramater to GWT "URL Parameters" section...but I don't want to limit Google from crawling these again...I figure I need Google to crawl them and see some code that says to get the pages out of their index...and THEN not crawl the pages anymore. I don't think the "Remove URL" feature in GWT will work, since that tool only removes URLs from the search results, not the actual Google index. FWIW, this site is using the Yoast plugin. We set every page type to "noindex" except for the homepage, Posts, Pages and Categories. We have other sites on Yoast that do not have any /feed URLs indexed by Google at all. Side note, the /robots.txt file was previously blocking crawling of the /feed URLs on this site, which is why you'll see that note in the Google SERPs when you click on the query link given in the first paragraph.

How does Google Crawl Multi-Regional Sites?
I've been reading up on this on Webmaster Tools but just wanted to see if anyone could explain it a bit better. I have a website which is going live soon which is going to be set up to redirect to a localised URL based on the IP address i.e. NZ IP ranges will go to .co.nz, Aus IP addresses would go to .com.au and then USA or other non-specified IP addresses will go to the .com address. There is a single CMS installation for the website. Does this impact the way in which Google is able to search the site? Will all domains be crawled or just one? Any help would be great - thanks!

Google's "cache:" operator is returning a 404 error.
I'm doing the "cache:" operator on one of my sites and Google is returning a 404 error. I've swapped out the domain with another and it works fine. Has anyone seen this before? I'm wondering if G is crawling the site now? Thx!

Can I format my H1 to be smaller than H2's and H3's on the same page?
I would like to create a web design with 12px H1 and for sub headings on the page to be more like 24px. Will search engines see this and dislike it? The reason for doing it is that I want to put a generic page title in the banner, and more poetic headings above the main body. Example: Small H1: Wholesale coffee, online coffee shop and London roastery Large h2: Respect the bean... Thanks
