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 to test Angular JS heavy page for SEO?
Hi Moz community, Our tech team has recently decided to try switching our product pages to be JavaScript dependent, this includes links, product descriptions and things like breadcrumbs in JS. Given my concerns, they will create a proof of concept with a few product pages in a QA environment so I can test the SEO implications of these changes. They are planning to use Angular 5 client side rendering without any prerendering. I suggested universal but they said the lift was too great, so we're testing to see if this works. I've read a lot of the articles in this guide to all things SEO and JS and am fairly confident in understanding when a site uses JS and how to troubleshoot to make sure everything is getting crawled and indexed. https://sitebulb.com/resources/guides/javascript-seo-resources/ However, I am not sure I'll be able to test the QA pages since they aren't indexable and lives behind a login. I will be able to crawl the page using Screaming Frog but that's generally regarded as what a crawler should be able to crawl and not really what Googlebot will actually be able to crawl and index. Any thoughts on this, is this concern valid? Thanks!

Problem with Yoast not seeing any of this website's text/content
Hi, My client has a new WordPress site http://www.londonavsolutions.co.uk/ and they have installed the Yoast Premium SEO plug-in. They are having issues with getting the lights to go green and the main problem is that on most pages Yoast does not see any words/content – although there are plenty of words on the pages. Other tools can see the words, however Yoast is struggling to find any and gives the following message:- Bad SEO score. The text contains 0 words. This is far below the recommended minimum of 300 words. Add more content that is relevant for the topic. Readability - You have far too little content. Please add some content to enable a good analysis. They have contacted the website developer who says that there is nothing wrong, but they are frustrated that they cannot use the Yoast tools themselves because of this issue, plus Yoast are offering no support with the issue. I hope that one of you guys has seen this problem before, or can spot a problem with the way the site has been built and can perhaps shed some light on the problem. I didn't build the site myself so won't be offended if you spot problems with it. Thanks in advance, Ben

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.

How Does Google's "index" find the location of pages in the "page directory" to return?
This is my understanding of how Google's search works, and I am unsure about one thing in specific: Google continuously crawls websites and stores each page it finds (let's call it "page directory") Google's "page directory" is a cache so it isn't the "live" version of the page Google has separate storage called "the index" which contains all the keywords searched. These keywords in "the index" point to the pages in the "page directory" that contain the same keywords. When someone searches a keyword, that keyword is accessed in the "index" and returns all relevant pages in the "page directory" These returned pages are given ranks based on the algorithm The one part I'm unsure of is how Google's "index" knows the location of relevant pages in the "page directory". The keyword entries in the "index" point to the "page directory" somehow. I'm thinking each page has a url in the "page directory", and the entries in the "index" contain these urls. Since Google's "page directory" is a cache, would the urls be the same as the live website (and would the keywords in the "index" point to these urls)? For example if webpage is found at wwww.website.com/page1, would the "page directory" store this page under that url in Google's cache? The reason I want to discuss this is to know the effects of changing a pages url by understanding how the search process works better.

Are Collapsible DIV's SEO-Friendly?
When I have a long article about a single topic with sub-topics I can make it user friendlier when I limit the text and hide text just showing the next headlines, by using expandable-collapsible div's. My doubt is if Google is really able to read onclick textlinks (with javaScript) or if it could be "seen" as hidden text? I think I read in the SEOmoz Users Guide, that all javaScript "manipulated" contend will not be crawled. So from SEOmoz's Point of View I should better make use of old school named anchors and a side-navigation to jump to the sub-topics? (I had a similar question in my post before, but I did not use the perfect terms to describe what I really wanted. Also my text is not too long (<1000 Words) that I should use pagination with rel="next" and rel="prev" attributes.) THANKS for every answer 🙂

NoIndex/NoFollow pages showing up when doing a Google search using "Site:" parameter
We recently launched a beta version of our new website in a subdomain of our existing site. The existing site is www.fonts.com with the beta living at new.fonts.com. We do not want Google to crawl the new site until it's out of beta so we have added the following on all pages: However, one of our team members noticed that google is displaying results from new.fonts.com when doing an "site:new.fonts.com" search (see attached screenshot). Is it possible that Google is indexing the content despite the noindex, nofollow tags? We have double checked the syntax and it seems correct except the trailing "/". I know Google still crawls noindexed pages, however, the fact that they're showing up in search results using the site search syntax is unsettling. Any thoughts would be appreciated! DyWRP.png

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.
