      Hi Moz Community,

      I have a question about personalization of content, can we serve personalized content without being penalized for serving different content to robots vs. users? If content starts in the same initial state for all users, including crawlers, is it safe to assume there should be no impact on SEO because personalization will not happen for anyone until there is some interaction?

      Thanks,

        It sounds like you're on the right track. If users and bots start off with the same content, that's a good start.

        From there, the question is "how much content is being customized, and how frequently?" For example, if you're swapping out 5 different headlines for 40% of users, and 60% of users see the original, that's not a big deal, particularly if the rest of the page is the same.

        But if you're swapping out 80% of page copy (eg removing a bunch of excess copy that is shown for SEO purposes), and 60-90% of users are seeing that "light" version of the page, you run the risk of two things:

        1. First, the chance that it wouldn't pass a manual review if one was performed.
        2. Second, the chance that Google may render a copy of the page as a user (not announcing themselves as a crawler), seeing a different version of the page multiple times, and then effectively devaluing the missing content, or worse, flagging the page in their system as cloaked content.

        We could get lost in details of whether or not they're doing this, or how they're doing this, but from a technology standpoint it's pretty simply for them to render content from non-official IPs and user-agents and do an 'honesty check' for situations where content is showing up multiple ways. This is already how them compare the page on desktop vs mobile to see which sections of the page render, and which are changed.

        I think you are also right to rely on site interaction before personalizing, but since there are multiple ways to do that, you should know that it's possible for Google to simulate some of those interactions. So there's a chance at some point they will render your content in a personalized manner, particularly if personalization is the result of visiting a URL or clicking a simple toggle switch or button.

          Page Indexing without content

          indexing seo

          Hello. I have a problem of page indexing without content. I have website in 3 different languages and 2 of the pages are indexing just fine, but one language page (the most important one) is indexing without content. When searching using site: page comes up, but when searching unique keywords for which I should rank 100% nothing comes up. This page was indexing just fine and the problem arose couple of days ago after google update finished. Looking further, the problem is language related and every page in the given language that is newly indexed has this problem, while pages that were last crawled around one week ago are just fine. Has anyone ran into this type of problem?

          Duplicate Content and Subdirectories

          duplicate content subdirectory directories

          Hi there and thank you in advance for your help! I'm seeking guidance on how to structure a resources directory (white papers, webinars, etc.) while avoiding duplicate content penalties. If you go to /resources on our site, there is filter function. If you filter for webinars, the URL becomes /resources/?type=webinar We didn't want that dynamic URL to be the primary URL for webinars, so we created a new page with the URL /resources/webinar that lists all of our webinars and includes a featured webinar up top. However, the same webinar titles now appear on the /resources page and the /resources/webinar page. Will that cause duplicate content issues? P.S. Not sure if it matters, but we also changed the URLs for the individual resource pages to include the resource type. For example, one of our webinar URLs is /resources/webinar/forecasting-your-revenue Thank you!

          Duplicate Content

          We have a ton of duplicate content/title errors on our reports, many of them showing errors of: http://www.mysite.com/(page title) and http://mysite.com/(page title) Our site has been set up so that mysite.com 301 redirects to www.mysite.com (we did this a couple years ago). Is it possible that I set up my campaign the wrong way in SEOMoz? I'm thinking it must be a user error when I set up the campaign since we already have the 301 Redirect. Any advice is appreciated!

          Localized domains and duplicate content

          Hey guys, In my company we are launching a new website and there's an issue it's been bothering me for a while. I'm sure you guys can help me out. I already have a website, let's say ABC.com I'm preparing a localized version of that website for the uk so we'll launch ABC.co.uk Basically the websites are going to be exactly the same with the difference of the homepage. They have a slightly different proposition. Using GeoIP I will redirect the UK traffic to ABC.co.uk and the rest of the traffic will still visit .com website. May google penalize this? The site itself it will be almost the same but the homepage. This may count as duplicate content even if I'm geo-targeting different regions so they will never overlap. Thanks in advance for you advice

          Duplicate Content and URL Capitalization

          I have multiple URLs that SEOMoz is reporting as duplicate content.  The reason is that there are characters in the URL that may, or may not, be capitalized depending on user input. A couple examples are: www.househitz.com/Pennsylvania/Houses-for-sale www.househitz.com/Pennsylvania/houses-for-sale www.househitz.com/Pennsylvania/Houses-for-rent www.househitz.com/Pennsylvania/houses-for-rent There are currently thousands of instances of this on the site. Is this something I should spend effort to try and resolve (may not be minor effort), or should I just ignore it and move on?

          Internal search : rel=canonical vs noindex vs robots.txt

          Hi everyone, I have a website with a lot of internal search results pages indexed. I'm not asking if they should be indexed or not, I  know they should not according to Google's guidelines. And they make a bunch of duplicated pages so I want to solve this problem. The thing is, if I noindex them, the site is gonna lose a non-negligible chunk of traffic : nearly 13% according to google analytics !!! I thought of blocking them in robots.txt. This solution would not keep them out of the index. But the pages appearing in GG SERPS would then look empty (no title, no description), thus their CTR would plummet and I would lose a bit of traffic too... The last idea I had was to use a rel=canonical tag pointing to the original search page (that is empty, without results), but it would probably have the same effect as noindexing them, wouldn't it ? (never tried so I'm not sure of this) Of course I did some research on the subject, but each of my finding recommanded one of the 3 methods only ! One even recommanded noindex+robots.txt block which is stupid because the noindex would then be useless... Is there somebody who can tell me which option is the best to keep this traffic ? Thanks a million

          Duplicate content and http and https

          Within my Moz crawl report, I have a ton of duplicate content caused by identical pages due to identical pages of http and https URL's. For example: http://www.bigcompany.com/accomodations https://www.bigcompany.com/accomodations The strange thing is that 99% of these URL's are not sensitive in nature and do not require any security features.  No credit card information, booking, or carts.  The web developer cannot explain where these extra URL's came from or provide any further information. Advice or suggestions are welcome!  How do I solve this issue? THANKS MOZZERS

          CGI Parameters: should we worry about duplicate content?

          Hi, My question is directed to CGI Parameters. I was able to dig up a bit of content on this but I want to make sure I understand the concept of CGI parameters and how they can affect indexing pages. Here are two pages: No CGI parameter appended to end of the URL: http://www.nytimes.com/2011/04/13/world/asia/13japan.html CGI parameter appended to the end of the URL: http://www.nytimes.com/2011/04/13/world/asia/13japan.html?pagewanted=2&ref=homepage&src=mv Questions: Can we safely say that CGI parameters = URL parameters that append to the end of a URL? Or are they different? And given that you have rel canonical implemented correctly on your pages, search engines will move ahead and index only the URL that is specified in that tag? Thanks in advance for giving your insights. Look forward to your response. Best regards, Jackson
