Bloking pages in roborts.txt that are under a redirected subdomain
-
Hi Everyone,
I have a lot of Marketo landing pages that I don't want to show in SERP. Adding the noindex meta tag for each page will be too much, I have thousands of pages.
Blocking it in roborts.txt could have been an option, BUT, the subdomain homepage is redirected to my main domain (with a 302) so I may confuse search engines ( should they follow the redirect or should they block)
marketo.mydomain.com is redirected to www.mydomain.com
disallow: / (I think this will be confusing with the redirect)
I don't have folders, all pages are under the subdomain, so I can't block folders in Robots.txt also
Would anyone had this scenario or any suggestions?
I appreciate your thoughts here.
Thank you
Rachel

Thank you so much for you answer!
the home page in the subdomain is redirected but none of the actual pages in the subdomain are, and because there are so many of them, it would be easier to block them in robots.txt, even if there is small change that Google will still index them. But because the home page is redirected, I don't want to confuse Google with a Disallow: /
Could I do Disallow: / and then Allow: /homepage.html

Under usual circumstances, Google won't index redirecting addresses which it considers to be a shallow form of 'doorway' page (Google doesn't like to rank those). If I am reading your post right, no pages on the redirected sub-domain can be visited as they all now redirect. Google should start dropping those old URLs from its index automatically. It's important to note that you should be using 301s to eventually de-index the old URLs. If you're using 302s then you're telling Google that the old pages are only being redirected temporarily and they will return (which could mess with indexation)
If I am reading your post wrong and some pages are still live on the old subdomain and are not redirecting, and you want Google to redirect most addresses but some are staying (for whatever reason) and you still want to de-index those specific ones, Meta no-index (sorry) really is your best bet! Robots.txt tells Google not to crawl a page but it doesn't tell Google not to index a URL if external metrics (inbound links) are strong enough. Both are 'directives' and Google is forced to obey neither
I think from what you are saying, I'd just leave the redirects and let Google do its work. Make sure they're 301s, though. You're right that Robots.txt might end up confusing things. Robots.txt can also sometimes 'kill' the SEO authority of a page. If you did that for all the redirecting pages, no equity would flow through your 301s (hazardous)

Crawl solutions for landing pages that don't contain a robots.txt file?
My site (www.nomader.com) is currently built on Instapage, which does not offer the ability to add a robots.txt file. I plan to migrate to a Shopify site in the coming months, but for now the Instapage site is my primary website. In the interim, would you suggest that I manually request a Google crawl through the search console tool? If so, how often? Any other suggestions for countering this Meta Noindex issue?

Will redirecting a logged in user from a public page to an equivalent private page (not visible to google) impact SEO?
Hi, We have public pages that can obviously be visited by our registered members. When they visit these public pages + they are logged in to our site, we want to redirect them to the equivalent (richer) page on the private site e.g. a logged in user visiting /public/contentA will be redirected to /private/contentA Note: Our /public pages are indexed by Google whereas /private pages are excluded. a) will this affect our SEO? b) if not, is 302 the best http status code to use? Cheers

Can Google show the hReview-Aggregate microformat in the SERPs on a product page if the reviews themselves are on a separate page?
Hi, We recently changed our eCommerce site structure a bit and separated our product reviews onto a a different page. There were a couple of reasons we did this : We used pagination on the product page which meant we got duplicate content warnings. We didn't want to show all the reviews on the product page because this was bad for UX (and diluted our keywords). We thought having a single page was better than paginated content, or at least safer for indexing. We found that Googlebot quite often got stuck in loops and we didn't want to bury the reviews way down in the site structure. We wanted to reduce our bounce rate a little, so having a different reviews page could help with this. In the process of doing this we tidied up our microformats a bit too. The product page used to have to three main microformats; hProduct hReview-Aggregate hReview The product page now only has hProduct and hReview-Aggregate (which is now nested inside the hProduct). This means the reviews page has hReview-Aggregate and hReviews for each review itself. We've taken care to make sure that we're specifying that it's a product review and the URL of that product. However, we've noticed over the past few weeks that Google has stopped feeding the reviews into the SERPs for product pages, and is instead only feeding them in for the reviews pages. Is there any way to separate the reviews out and get Google to use the Microformats for both pages? Would using microdata be a better way to implement this? Thanks,

If a permanent redirect is supposed to transfer SEO from the old page to the new page, why has my domain authority been impacted?
For example, we redirected our old domain to a new one (leaving no duplicate content on the old domain) and saw a 40% decrease in domain authority. Isn't a permanent redirect supposed to transfer link authority to the place it is redirecting to? Did I do something wrong?

We're working on a site that is a beer company. Because it is required to have an age verification page, how should we best redirect the bots (useragents) to the actual homepage (thus skipping ahead of the age verification without allowing all browsers)?
This question is about useragents and alcohol sites that have an age verification screen upon landing on the site.

301 lots of old pages to home page
Will it hurt me if i redirect a few hundred old pages to my home page? I currently have a mess on my hands with many 404's showing up after moving my site to a new ecommerce server. We have been at the new server for 2 years but still have 337 404s showing up in google webmaster tools. I don't think it would affect users as very few people woudl find those old links but I don't want to mess with google. Also, how much are those 404s hurting my rank?

Too many on page links for WP blog page
Hello, I have set my WP blog to a page so new posts go to that page making it the blog. On a SEOmoz campaign crawl, it says there are too many links on one page, so does this mean that as I am posting my blog posts to this page, the search engines are seeing the page as one page with links instead of the blog posts? I worry that if I continue to add more posts (which obviously I want to) the links will increase more and more, meaning that they will be discounted due to too many links. What can I do to rectify this? Many thanks in advance
