Prevent Google from crawling Ajax
-
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

Google Pagination Changes
What with Google recently coming out and saying they're basically ignoring paginated pages, I'm considering the link structure of our new, sooner to launch ecommerce site (moving from an old site to a new one with identical URL structure less a few 404s). Currently our new site shows 20 products per page but with this change by Google it means that any products on pages 2, 3 and so on will suffer because google treats it like an entirely separate page as opposed to an extension of the first. The way I see it I have one option: Show every product in each category on page 1. I have Lazy Load installed on our new website so it will only load the screen a user can see and as they scroll down it loads more products, but how will google interpret this? Will Google simply see all 50-300 products per category and give the site a bad page load score because it doesn't know the Lazy Load is in place? Or will it know and account for it? Is there anything I'm missing?

Brand name not ranking in Google
Hi Moz'ers, Could you help me with something I cannot seem to figure out by myself. In June 2017 my company started a rebranding campaign. We've changed our brand name and launched a new website: https://spotler.com. Everything is going fine, but if you Google our brand name "Spotler" our website doesn't show up. How can it be? Our domain authority is 38. It would be wonderful if you could help me. Let me know if you need more information. Best, Simone

Subdomain replaced domain in Google SERP
Good morning, This is my first post. I found many Q&As here that mostly answer my question, but just to be sure we do this right I'm hoping the community can take a peak at my thinking below: Problem: We are relevant rank #1 for "custom poker chips" for example. We have this development website on a subdomain (http://dev.chiplab.com). On Saturday our live 'chiplab.com' main domain was replaced by 'dev.chiplab.com' in the SERP. Expected Cause: We did not add NOFOLLOW to the header tag. We also did not DISALLOW the subdomain in the robots.txt. We could have also put the 'dev.chiplab.com' subdomain behind a password wall. Solution: Add NOFOLLOW header, update robots.txt on subdomain and disallow crawl/index. Question: If we remove the subdomain from Google using WMT, will this drop us completely from the SERP? In other words, we would ideally like our root chiplab.com domain to replace the subdomain to get us back to where we were before Saturday. If the removal tool in WMT just removes the link completely, then is the only solution to wait until the site is recrawled and reindexed and hope the root chiplab.com domain ranks in place of the subdomain again? Thank you for your time, Chase

Mass Removal Request from Google Index
Hi, I am trying to cleanse a news website. When this website was first made, the people that set it up copied all kinds of articles they had as a newspaper, including tests, internal communication, and drafts. This site has lots of junk, but this kind of junk was on the initial backup, aka before 1st-June-2012. So, removing all mixed content prior to that date, we can have pure articles starting June 1st, 2012! Therefore My dynamic sitemap now contains only articles with release date between 1st-June-2012 and now Any article that has release date prior to 1st-June-2012 returns a custom 404 page with "noindex" metatag, instead of the actual content of the article. The question is how I can remove from the google index all this junk as fast as possible that is not on the site anymore, but still appears in google results? I know that for individual URLs I need to request removal from this link
Intermediate & Advanced SEO | | ioannisa
https://www.google.com/webmasters/tools/removals The problem is doing this in bulk, as there are tens of thousands of URLs I want to remove. Should I put the articles back to the sitemap so the search engines crawl the sitemap and see all the 404? I believe this is very wrong. As far as I know this will cause problems because search engines will try to access non existent content that is declared as existent by the sitemap, and return errors on the webmasters tools. Should I submit a DELETED ITEMS SITEMAP using the <expires>tag? I think this is for custom search engines only, and not for the generic google search engine.
https://developers.google.com/custom-search/docs/indexing#on-demand-indexing</expires> The site unfortunatelly doesn't use any kind of "folder" hierarchy in its URLs, but instead the ugly GET params, and a kind of folder based pattern is impossible since all articles (removed junk and actual articles) are of the form:
http://www.example.com/docid=123456 So, how can I bulk remove from the google index all the junk... relatively fast?0 -
Pagination loading with using AJAX. Should I change this?
Hello, while I was checking this site; http://www.disfracessimon.com/disfraces-adultos-16.html I found that the pagination is working this way http://www.disfracessimon.com/disfraces-adultos-16.html#/page-2
Intermediate & Advanced SEO | | teconsite
http://www.disfracessimon.com/disfraces-adultos-16.html#/page-3 and content is being loaded using AJAX. So, google is not getting the paginated results. Is this a big issue or there is no problem?
Should I create a link for See All Products or there is not a big issue? Thank you!0 -
How does Google know if a backlink is good or not?
Hi, What does Google look at when assessing a backlink? How important is it to get a backlink from a website with relevant content? Ex: 1. Domain/Page Auth 80, website is not relevant. Does not use any of the words in your target term in any area of the website. 2. Domain/Page Auth 40, website is relevant. Uses the words in your target term multiple times across website. Which website example would benefit your SERP's more if you gained a backlink? (and if you can say, how much more would it benefit - low, medium, high).

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.
