Blocking Google from telemetry requests
At Magnet.me we track the items people are viewing in order to optimize our recommendations. As such we fire POST requests back to our backends every few seconds when enough user initiated actions have happened (think about scrolling for example). In order to eliminate bots from distorting statistics we ignore their values serverside. Based on some internal logging, we see that Googlebot is also performing these POST requests in its javascript crawling. In a 7 day period, that amounts to around 800k POST requests. As we are ignoring that data anyhow, and it is quite a number, we considered reducing this for bots. Though, we had several questions about this:

1. Do these requests count towards crawl budgets?
2. If they do, and we'd want to prevent this from happening: what would be the preferred option? Either preventing the request in the frontend code, or blocking the request using a robots.txt line? The latter question is given by the fact that a in-app block for the request could lead to different behaviour for users and bots, and may be Google could penalize that as cloaking. The latter is slightly less convenient from a development perspective, as all logic is spread throughout the application. I'm aware one should not cloak, or makes pages appear differently to search engine crawlers. However these requests do not change anything in the pages behaviour, and purely send some anonymous data so we can improve future recommendations.0 -

Duplicate Content - Captcha on Contact Form
I am going to be working on a site where the contact form is being flagged as duplicate content the URL is the same apart from having: /contact/10119 contact/31010 ...at the end of it. The only difference in the content of the page that I can see is the Captcha numbers? Is there a way to overcome this to stop duplicate content? Thanks in advance

Google insists robots.txt is blocking... but it isn't.
I recently launched a new website. During development, I'd enabled the option in WordPress to prevent search engines from indexing the site. When the site went public (over 24 hours ago), I cleared that option. At that point, I added a specific robots.txt file that only disallowed a couple directories of files. You can view the robots.txt at http://photogeardeals.com/robots.txt Google (via Webmaster tools) is insisting that my robots.txt file contains a "Disallow: /" on line 2 and that it's preventing Google from indexing the site and preventing me from submitting a sitemap. These errors are showing both in the sitemap section of Webmaster tools as well as the Blocked URLs section. Bing's webmaster tools are able to read the site and sitemap just fine. Any idea why Google insists I'm disallowing everything even after telling it to re-fetch?

Blocking https from being crawled
I have an ecommerce site where https is being crawled for some pages. Wondering if the below solution will fix the issue www.example.com will be my domain In the nav there is a login page www.example.com/login which is redirecting to the https://www.example.com/login If I just disallowed /login in the robots file wouldn't it not follow the redirect and index that stuff? The redirect part is what I am questioning.

I am trying to block robots from indexing parts of my site..
I have a few websites that I mocked up for clients to check out my work and get a feel for the style I produce but I don't want them indexed as they have lore ipsum place holder text and not really optimized... I am in the process of optimizing them but for the time being I would like to block them. Most of my warnings and errors on my seomoz dashboard are from these sites and I was going to upload the folioing to the robot.txt file but I want to make sure this is correct: User-agent: * Disallow: /salondemo/ Disallow: /salondemo3/ Disallow: /cafedemo/ Disallow: /portfolio1/ Disallow: /portfolio2/ Disallow: /portfolio3/ Disallow: /salondemo2/ is this all i need to do? Thanks Donny

Blocking AJAX Content from being crawled
Our website has some pages with content shared from a third party provider and we use AJAX as our implementation. We dont want Google to crawl the third party's content but we do want them to crawl and index the rest of the web page. However, In light of Google's recent announcement about more effectively indexing google, I have some concern that we are at risk for that content to be indexed. I have thought about x-robots but have concern about implementing it on the pages because of a potential risk in Google not indexing the whole page. These pages get significant traffic for the website, and I cant risk. Thanks, Phil

Micro formats to block HTML text portions of pages
I have a client that wants to use micro formatting to keep a portion of their page (the disclaimer) from being read by the search engines. They want to do this because it will help with their keyword density on the rest of the page and block the “bad keywords” that come from their legally required disclaimer. We have suggested alternate methods to resolve this problem, but they do not want to implement those, they just want a POV from us explaining how this micro formatting process will work. And that’s where the problem is. I’ve never heard of this use case and can’t seem to find anyone who has. I'm posting the question to the Moz Community to see if anyone knows how microformats can keep copy from being crawled by the bots. Please include any links to sites that you know that are using micro formatting in this way. Have you implemented it and seen results? Do you know of a website that is using it now? We're looking for use cases please!
