      With Google figuring out how to make Ajax and JS more searchable/indexable, I am curious on thoughts or techniques to prevent this.

      Here's my Situation, we have a page that we do not ever want to be indexed/crawled or other. Currently we have the nofollow/noindex command, but due to technical changes for our site the method in which this information is being implemented if it is ever displayed it will not have the ability to block the content from search. It is also the decision of the business to not list the file in robots.txt due to the sensitivity of the content. Basically, this content doesn't exist unless something super important happens, and even if something super important happens, we do not want Google to know of its existence.

      Since the Dev team is planning on using Ajax/JS to pull in this content if the business turns it on, the concern is that it will be on the homepage and Google could index it. So the questions that I was asked; if Google can/does index, how long would that piece of content potentially appear in the SERPs? Can we block Google from caring about and indexing this section of content on the homepage?

      Sorry for the vagueness of this question, it's very sensitive in nature and I am trying to avoid too many specifics. I am able to discuss this in a more private way if necessary.

      Thanks!

        Toby, thanks for the suggestion! I believe that this will help accomplish what we need. My Dev gave the "oh S" I should've thought of that response.

          You may find that you have to wrap the code that gets called when Ajax fires in something to catch the user agent. I.e. if your making an Ajax request to a php script in order to return data, you could wrap that php code in something like this (please excuse the Sudo code):

          if(in_array($_SERVER['HTTP_USER_AGENT'], $knownagents){

          //known webspider, or blocked agent, return nothing.

          return "";

          } else {

          //not a known spider so continue.

          }

          ?>

          Thats very generalised but you get the idea. I put a short list together in JSON format a while back, you can find it here if its of any use: https://www.source-control.co.uk/knownspiders/spiders.php

          PM me if you need any more specific help than that with development, hopefully someone else will have a slightly easier way of dealing with this though heh

            How can I make sure Google is crawling a link from an iframe (video)?

            Do they crawl backlinks from an iframe example from a Youtube video embedded in a blog post? TIA!

            Pages are Indexed but not Cached by Google. Why?

            Here's an example: I get a 404 error for this: http://webcache.googleusercontent.com/search?q=cache:http://www.qjamba.com/restaurants-coupons/ferguson/mo/all But a search for qjamba restaurant coupons gives a clear result as does this: site:http://www.qjamba.com/restaurants-coupons/ferguson/mo/all What is going on?  How can this page be indexed but not in the Google cache? I should make clear that the page is not showing up with any kind of error in webmaster tools, and Google has been crawling pages just fine.  This particular page was fetched by Google yesterday with no problems, and even crawled again twice today by Google  Yet, no cache.

            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

            How is Google crawling and indexing this directory listing?

            We have three Directory Listing pages that are being indexed by Google: http://www.ccisolutions.com/StoreFront/jsp/ http://www.ccisolutions.com/StoreFront/jsp/html/ http://www.ccisolutions.com/StoreFront/jsp/pdf/ How and why is Googlebot crawling and indexing these pages? Nothing else links to them (although the /jsp.html/ and /jsp/pdf/ both link back to /jsp/). They aren't disallowed in our robots.txt file and I understand that this could be why. If we add them to our robots.txt file and disallow, will this prevent Googlebot from crawling and indexing those Directory Listing pages without prohibiting them from crawling and indexing the content that resides there which is used to populate pages on our site? Having these pages indexed in Google is causing a myriad of issues, not the least of which is duplicate content. For example, this file <tt>CCI-SALES-STAFF.HTML</tt> (which appears on this Directory Listing referenced above - http://www.ccisolutions.com/StoreFront/jsp/html/) clicks through to this Web page: http://www.ccisolutions.com/StoreFront/jsp/html/CCI-SALES-STAFF.HTML This page is indexed in Google and we don't want it to be. But so is the actual page where we intended the content contained in that file to display: http://www.ccisolutions.com/StoreFront/category/meet-our-sales-staff As you can see, this results in duplicate content problems. Is there a way to disallow Googlebot from crawling that Directory Listing page, and, provided that we have this URL in our sitemap: http://www.ccisolutions.com/StoreFront/category/meet-our-sales-staff, solve the duplicate content issue as a result? For example: Disallow: /StoreFront/jsp/ Disallow: /StoreFront/jsp/html/ Disallow: /StoreFront/jsp/pdf/ Can we do this without risking blocking Googlebot from content we do want crawled and indexed? Many thanks in advance for any and all help on this one!

            Does Google hate wordpress?

            I have my categories pages set to noindex, follow. I deactivated the author and date based archives, and all the /page/2 /page/3 are noindex. Is this the right approach? I had thought about adding some text to the topic of each category page and then changing them to index. I'm using showing recent post excerpts on the homepage. Another other suggestions? I think two of my sites are in panda for no good reason. It seems like non-wordpress blogs in my industry do better than comparable wordpress sites.

            Google News URL Structure

            Hi there folks I am looking for some guidance on Google News URLs. We are restructuring the site. A main traffic driver will be the traffic we get from Google News. Most large publishers use: www.site.com/news/12345/this-is-the-title/ Others use www.example.com/news/celebrity/12345/this-is-the-title/ etc. www.example.com/news/celebrity-news/12345/this-is-the-title/ www.example.com/celebrity-news/12345/this-is-the-title/ (Celebrity is a channel on Google News so should we try and follow that format?) www.example.com/news/celebrity-news/this-is-the-title/12345/ www.example.com/news/celebrity-news/this-is-the-title-12345/ (unique ID no at the end and part of the title URL) www.example.com/news/celebrity-news/celebrity-name/this-is-the-title-12345/ Others include the date. So as you can see there are so many combinations and there doesnt seem to be any unity across news sites for this format. Have you any advice on how to structure these URLs? Particularly if we want to been seen as an authority on the following topics: fashion, hair, beauty, and celebrity news - in particular "celebrity name" So should the celebrity news section be www.example.com/news/celebrity-news/celebrity-name/this-is-the-title-12345/ or what? This is for a completely new site build. Thanks Barry

            Does Google index url with hashtags?

            We are setting up some Jquery tabs in a page that will produce the same url with hashtags. For example: index.php#aboutus, index.php#ourguarantee, etc. We don't want that content to be crawled as we'd like to prevent duplicate content. Does Google normally crawl such urls or does it just ignore them? Thanks in advance.
