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.

What's the best way for users to upload their images to my wordpress site to promote UGC
I have looked at lots of different plugins and wanted a recommendation for an easy way for patients of ours to upload pictures of them out partying and having fun and looking beautiful so future users can see the final results instead of sometimes gory or difficult to understand before and after images. I'd like to give them the opportunity to write captions (like facebook or insta posts and would offer them incentives to do so. I don't want it to be too complicated for them or have too many steps or barriers but I do want it to look nice and slick and modern. Also do you think this would have a positive impact on SEO? I was also thinking of a Q&A app where dentists could get Q&A emails and respond - i've been doing AMA sessions and they've been really successful and I would like to bring it into out site and make it native. Thanks in advance 🙂

Good alternatives to Xenu's Link Sleuth and AuditMyPc.com Sitemap Generator
I am working on scraping title tags from websites with 1-5 million pages. Xenu's Link Sleuth seems to be the best option for this, at this point. Sitemap Generator from AuditMyPc.com seems to be working too, but it starts handing up, when a sitemap file, the tools is working on,becomes too large. So basically, the second one looks like it wont be good for websites of this size. I know that Scrapebox can scrape title tags from list of url, but this is not needed, since this comes with both of the above mentioned tools. I know about DeepCrawl.com also, but this one is paid, and it would be very expensive with this amount of pages and websites too (5 million ulrs is $1750 per month, I could get a better deal on multiple websites, but this obvioulsy does not make sense to me, it needs to be free, more or less). Seo Spider from Screaming Frog is not good for large websites. So, in general, what is the best way to work on something like this, also time efficient. Are there any other options for this? Thanks.

Google stopped crawling my site. Everybody is stumped.
This has stumped the Wordpress staff and people in the Google Webmasters forum. We are in Google News (have been for years), and so new posts are crawled immediately. On Feb 17-18 Crawl Stats dropped 85%, and new posts were no longer indexed (not appearing on News or search). Data highlighter attempts return "This URL could not be found in Google's index." No manual actions by Google. No changes to the website; no custom CSS. No Site Errors or new URL errors. No sitemap problems (resubmitting didn't help). We're on wordpress.com, so no odd code. We can see the robot.txt file. Other search engines can see us, as can social media websites. Older posts still index, but loss of News is a big hit. Also, I think overall Google referrals are dropping. We can Fetch the URL for a new post, and many hours later it appears on Google and News, and we can then use Data Highlighter. It's now 6 days and no recovery. Everybody is stumped. Any ideas? I just joined, so this might be the wrong venue. If so, apologies.

Blank pages in Google's webcache
Hello all, Is anybody experiencing blanck page's in Google's 'Cached' view? I'm seeing just the page background and none of the content for a couple of my pages but when I click 'View Text Only' all of teh content is there. Strange! I'd love to hear if anyone else is experiencing the same. Perhaps this is something to do with the roll out of Google's updates last week?! Thanks,

Blocking URL's with specific parameters from Googlebot
Hi, I've discovered that Googlebot's are voting on products listed on our website and as a result are creating negative ratings by placing votes from 1 to 5 for every product. The voting function is handled using Javascript, as shown below, and the script prevents multiple votes so most products end up with a vote of 1, which translates to "poor". How do I go about using robots.txt to block a URL with specific parameters only? I'm worried that I might end up blocking the whole product listing, which would result in de-listing from Google and the loss of many highly ranked pages. DON'T want to block: http://www.mysite.com/product.php?productid=1234 WANT to block: http://www.mysite.com/product.php?mode=vote&productid=1234&vote=2 Javacript button code: onclick="javascript: document.voteform.submit();" Thanks in advance for any advice given. Regards,

How to use overlays without getting a Google penalty
One of my clients is an email subscriber-led business offering deals that are time sensitive and which expire after a limited, but varied, time period. Each deal is published on its own URL and in order to drive subscriptions to the email, an overlay was implemented that would appear over the individual deal page so that the user was forced to subscribe if they wished to view the details of the deal. Needless to say, this led to the threat of a Google penalty which _appears (fingers crossed) _to have been narrowly avoided as a result of a quick response on our part to remove the offending overlay. What I would like to ask you is whether you have any safe and approved methods for capturing email subscribers without revealing the premium content to users before they subscribe? We are considering the following approaches: First Click Free for Web Search - This is an opt in service by Google which is widely used for this sort of approach and which stipulates that you have to let the user see the first item they click on from the listings, but can put up the subscriber only overlay afterwards. No Index, No follow - if we simply no index, no follow the individual deal pages where the overlay is situated, will this remove the "cloaking offense" and therefore the risk of a penalty? Partial View - If we show one or two paragraphs of text from the deal page with the rest being covered up by the subscribe now lock up, will this still be cloaking? I will write up my first SEOMoz post on this once we have decided on the way forward and monitored the effects, but in the meantime, I welcome any input from you guys.
