      Is it legit to show different content to http request having different referrer?

      case a: user view one page of the site with plenty of information about one brand, and click on a link on that page to see a product detail page of that brand, here I don't want to repeat information about the brand itself

      case b: a user view directly the product detail page clicking on a SERP result, in this case I would like to show him few paragraph about the brand

      Is it bad? Anyone have experience in doing it?

      My main concern is google crawler. Should not be considered cloaking because I am not differentiating on user-agent bot-no-bot.

      But when google is crawling the site which referrer will use? I have no idea, does anyone know?

      When going from one link to another on the website, is google crawler leaving the referrer empty?

        After googling about it and thinking better I choose not too. I think you are absolutely right, too inconsistent.

          You won't get a referrer. Googlebot is not like a real user, surfing from site to site. What Googlebot does is this (more or less)

          1. Googlebot requests a standalone page
          2. Googlebot parses the page out. During this process it notes the links on that page and, depending on various mechanisms (nofollow, internal page rank, the mood of Matt Cutts, etc) it will note those links for the system to parse later
          3. Googlebot is done so it grabs another page off the page list (likely without know how it got on said list) and goes back to #1

          Now, to your question. Since Googlebot has no referrer it won't get your alternate content. This means that your alternate content page won't get indexed.

          I would suggest here that a best practice is NOT to filter on referrer data, which can be inconsistent and potentially fake. Instead, I would make a separate page that contains your extra data and allow users to decide if they want more information Thus Googlebot finds all your content and your users get a better experience.

            URL structure - Page Path vs No Page Path

            We are currently re building our URL structure for eccomerce websites. We have seen a lot of site removing the page path on product pages e.g. https://www.theiconic.co.nz/liberty-beach-blossom-shirt-680193.html versus what would normally be https://www.theiconic.co.nz/womens-clothing-tops/liberty-beach-blossom-shirt-680193.html Should we be removing the site page path for a product page to keep the url shorter or should we keep it? I can see that we would loose the hierarchy juice to a product page but not sure what is the right thing to do.

            If a page ranks in the wrong country and is redirected, does that problem pass to the new page?

            Hi guys, I'm having a weird problem: A new multilingual site was launched about 2 months ago. It has correct hreflang tags and Geo targetting in GSC for every language version. We redirected some relevant pages (with good PA) from another website of our client's. It turned out that the pages were not ranking in the correct country markets (for example, the en-gb page ranking in the USA). The pages from our site seem to have the same problem. Do you think they inherited it due to the redirects? Is it possible that Google will sort things out over some time, given the fact that the new pages have correct hreflangs? Is there stuff we could do to help ranking in the correct country markets?

            Should I use noindex or robots to remove pages from the Google index?

            I have a Magento site and just realized we have about 800 review pages indexed. The /review directory is disallowed in robots.txt but the pages are still indexed. From my understanding robots means it will not crawl the pages BUT if the pages are still indexed if they are linked from somewhere else. I can add the noindex tag to the review pages but they wont be crawled. https://www.seroundtable.com/google-do-not-use-noindex-in-robots-txt-20873.html Should I remove the robots.txt and add the noindex? Or just add the noindex to what I already have?

            Google Adsbot crawling order confirmation pages?

            Hi, We have had roughly 1000+ requests per 24 hours from Google-adsbot to our confirmation pages. This generates an error as the confirmation page cannot be viewed after closing or by anyone who didn't complete the order. How is google-adsbot finding pages to crawl that are not linked to anywhere on the site, in the sitemap or linked to anywhere else? Is there any harm in a google crawler receiving a higher percentage of errors - even though the pages are not supposed to be requested. Is there anything we can do to prevent the errors for the benefit of our network team and what are the possible risks of any measures we can take? This bot seems to be for evaluating the quality of landing pages used in for Adwords so why is it trying to access confirmation pages when they have not been set for any of our adverts? We included "Disallow: /confirmation" in the robots.txt but it has continued to request these pages, generating a 403 page and an error in the log files so it seems Adsbot doesn't follow robots.txt. Thanks in advance for any help, Sam

            Substantial difference between Number of Indexed Pages and Sitemap Pages

            Hey there, I am doing a website audit at the moment. I've notices substantial differences in the number of pages indexed (search console), the number of pages in the sitemap and the number I am getting when I crawl the page with screamingfrog (see below). Would those discrepancies concern you? The website and its rankings seems fine otherwise. Total indexed: 2,360 (Search Consule)
            About 2,920 results (Google search "site:example.com")
            Sitemap: 1,229 URLs
            Screemingfrog Spider: 1,352 URLs Cheers,
            Jochen

            Blocking Pages Via Robots, Can Images On Those Pages Be Included In Image Search

            Hi! I have pages within my forum where visitors can upload photos.  When they upload photos they provide a simple statement about the photo but no real information about the image,definitely not enough for the page to be deemed worthy of being indexed.  The industry however is one that really leans on images and having the images in Google Image search is important to us. The url structure is like such:  domain.com/community/photos/~username~/picture111111.aspx I wish to block the whole folder from Googlebot to prevent these low quality pages from being added to Google's main SERP results.  This would be something like this: User-agent: googlebot Disallow: /community/photos/ Can  I disallow Googlebot specifically rather than just using User-agent:  * which would then allow googlebot-image to pick up the photos?  I plan on configuring a way to add meaningful alt attributes and image names to assist in visibility, but the actual act of blocking the pages and getting the images picked up... Is this possible? Thanks! Leona

            NOINDEX listing pages: Page 2, Page 3... etc?

            Would it be beneficial to NOINDEX category listing pages except for the first page.  For example on this site: http://flyawaysimulation.com/downloads/101/fsx-missions/ Has lots of pages such as Page 2, Page 3, Page 4... etc: http://www.google.com/search?q=site%3Aflyawaysimulation.com+fsx+missions Would there be any SEO benefit of NOINDEX on these pages?  Of course, FOLLOW is default, so links would still be followed and juice applied. Your thoughts and suggestions are much appreciated.

            Should the sitemap include just menu pages or all pages site wide?

            I have a Drupal site that utilizes Solr, with 10 menu pages and about 4,000 pages of content. Redoing a few things and we'll need to revamp the sitemap. Typically I'd jam all pages into a single sitemap and that's it, but post-Panda, should I do anything different?
