      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.

            Home Page Disappears From Google - But Rest of Site Still Ranked

            As title suggests we are running into a serious issue of the home page disapearing from Google search results whilst the rest of the site still remains. We search for it naturally cannot find a trace, then use a "site:" command in Google and still the home page does not come up. We go into web masters and inspect the home page and even Google states that the page is indexable. We then run the "Request Indexing" and the site comes back on Google. This is having a damaging affect and we would like to understand why this issue is happening. Please note this is not happening on just one of our sites but has happened to three which are all located on the same server. One of our brand which has the issue is: www.henweekends.co.uk

            Category Page as Shopping Aggregator Page

            Hi, I have been reviewing the info from Google on structured data for products and started to ponder. 
            https://developers.google.com/search/docs/data-types/products Here is the scenario.
            You have a Category Page and it lists 8 products, each products shows an image, price and review rating. As the individual products pages are already marked up they display Rich Snippets in the serps. 
            I wonder how do we get the rich snippets for the category page. Now Google suggest a markup for shopping aggregator pages that lists a single product, along with information about different sellers offering that product but nothing for categories. My ponder is this, Can we use the shopping aggregator markup for category pages to achieve the coveted rich results (from and to price, average reviews)? Keen to hear from anyone who has had any thoughts on the matter or had already tried this.

            Is possible to submit a XML sitemap to Google without using Google Search Console?

            We have a client that will not grant us access to their Google Search Console (don't ask us why). Is there anyway possible to submit a XML sitemap to Google without using GSC? Thanks

            Google indexing only 1 page out of 2 similar pages made for different cities

            We have created two category pages, in which we are showing products which could be delivered in separate cities. Both pages are related to cake delivery in that city. But out of these two category pages only 1 got indexed in google and other has not. Its been around 1 month but still only Bangalore category page got indexed. We have submitted sitemap and google is not giving any crawl error. We have also submitted for indexing from "Fetch as google" option in webmasters. www.winni.in/c/4/cakes (Indexed - Bangalore page - http://www.winni.in/sitemap/sitemap_blr_cakes.xml) 2. http://www.winni.in/hyderabad/cakes/c/4 (Not indexed - Hyderabad page - http://www.winni.in/sitemap/sitemap_hyd_cakes.xml) I tried searching for "hyderabad site:www.winni.in" in google but there also http://www.winni.in/hyderabad/cakes/c/4 this link is not coming, instead of this only www.winni.in/c/4/cakes is coming. Can anyone please let me know what could be the possible issue with this?

            How do you check the google cache for hashbang pages?

            So we use http://webcache.googleusercontent.com/search?q=cache:x.com/#!/hashbangpage to check what googlebot has cached but when we try to use this method for hashbang pages, we get the x.com's cache... not x.com/#!/hashbangpage That actually makes sense because the hashbang is part of the homepage in that case so I get why the cache returns back the homepage. My question is - how can you actually look up the cache for hashbang page?

            Google Analytics: how to filter out pages with low bounce rate?

            Hello here, I am trying to find out how I can filter out pages in Google Analytics according to their bounce rate. The way I am doing now is the following: 1. I am working inside the Content > Site Content > Landing Pages report 2. Once there, I click the "advanced" link on the right of the filter field. 3. Once there, I define to "include" "Bounce Rate" "Greater than" "0.50" which should show me which pages have a bounce rate higher of 0.50%.... instead I get the following warning on the graph: "Search constraints on metrics can not be applied to this graph" I am afraid I am using the wrong approach... any ideas are very welcome! Thank you in advance.

            How long does google take to show the results in SERP once the pages are indexed ?

            Hi...I am a newbie & trying to optimize the website www.peprismine.com. I have 3 questions - A little background about this : Initially, close to 150 pages were indexed by google. However, we decided to remove close to 100 URLs (as they were quite similar). After the changes, we submitted the NEW sitemap (with close to 50 pages) & google has indexed those URLs in sitemap. 1. My pages were indexed by google few days back. How long does google take to display the URL in SERP once the pages get indexed ? 2. Does google give more preference to websites with more number of pages than those with lesser number of pages to display results in SERP (I have just 50 pages). Does the NUMBER of pages really matter ? 3. Does removal / change of URLs have any negative effect on ranking ? (Many of these URLs were not shown on the 1st page) An answer from SEO experts will be highly appreciated. Thnx !

            Indexed Pages in Google, How do I find Out?

            Is there a way to get a list of pages that google has indexed? Is there some software that can do this? I do not have access to webmaster tools, so hoping there is another way to do this. Would be great if I could also see if the indexed page is a 404 or other Thanks for your help, sorry if its  basic question 😞
