      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.

            Can Google Bot View Links on a Wix Page?

            Hi, The way Wix is configured you can't see any of the on-page links within the source code. Does anyone know if Google Bots still count the links on this page? Here is the page in question: https://www.ncresourcecenter.org/business-directory If you do think Google counts these links, can you please send me URL fetcher to prove that the links are crawlable? Thank you SO much for your help.

            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?

            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

            Google Rich Snippets in E-commerce Category Pages

            Hello Best Practice for rich snippets / structured data in ecommerce category pages? I put structured markup in the category pages and it seems to have negatively impacted SEO.  Webmaster tools is showing about 2.5:1 products to pages ratio. Should I be putting structured data in category Pages at all? Thanks for your time 🙂

            Why does Google add my domain as a suffix to page title in SERPS?

            Hi, If I do a search in Google - for one our products on our site, our site comes up - but it would appear that google is adding our domain name as a suffix to our title in the results... Anyone else seen this? Can I do anything about it? I would prefer it not to appear. Thanks!

            How to find all indexed pages in Google?

            Hi, We have an ecommerce site with around 4000 real pages. But our index count is at 47,000 pages in Google Webmaster Tools. How can I get a list of all pages indexed of our domain? trying to locate the duplicate content. Doing a "site:www.mydomain.com" only returns up to 676 results... Any ideas? Thanks, Ben
