      According to: https://developers.google.com/structured-data/rich-snippets/reviews - all someone has to do is add in some html code and write the review. How does google do any validation on whether these reviews are legitimate or not?

        Hi Lingke!

        Good feedback from everyone here. I just wanted to be sure to throw into the mix that fact that John Mueller specifically stated last December that Google does not want markup on on-site testimonials:

        https://productforums.google.com/forum/#!topic/webmasters/wY1vF2RRos4/discussion

        More on this here:

          My guess is that Google is getting better and better at detecting false review data. There is a lot of academic research around this area, particularly in accounting fraud, where patterns created by humans to appear random do a poor job of actually representing standard data. A popular example of this is called Benford's Law where leading digits of certain data sets (like electricity bills) are more likely to be lower digits (starting with the number 1, for example). When people try and fake the data, they don't tend to follow this law.

          Google has huge data sets on validated reviews and known-fraudulent reviews. If there is a way to detect unbelievable reviews, you got to believe Google is working on it.

          That being said, this is probably the best reason not to start posting fake reviews... it's illegal.

            The answer here is "no" Google has no idea if they are fake or not.  Google may be able to tell if the reviews are duplicated on other sites (as it can do with other content) and so could in theory not rank the pages with the duplicate content/reviews. A common recommendation we give to a small business is to not copy reviews from other sites for this reason, and usually reprinting reviews are a violation of the TOS of the review site.   I would speculate that Google could look at the overall reputation/authority of a site to see if they display snippets, but that it really only a guess on my part.

            The only thing that Google can validate, to a degree, are the reviews that come through Google+ type profiles.  They can do things like see if a profile was created, gave a single positive review and then the user never logs in again. That would obviously be a suspect pattern and there are for sure other examples. I have seen Google sometimes do things like look at a business, see if it has a validated Google Local profile and if they do, Google will pull in reviews from review sites and display them in the Google local cards.  There is a bit of validation there as the business has taken the time to verify itself in Google Local.

            That said, I would say many users can tell a fake review a mile away.  We bring focus groups onto a review site I help with and they can tell when things look "off".   I would not waste my time with fake ones for that reason alone.

            Also, if you do have legitimate reviews, you do need to make sure the markup is correct if you want the snippets to show in the SERPs.  If your markup is not valid the snippets will not show up. The Rich Snippets testing tool can help with this

              How good/bad the exit intent pop-ups? What is Google's perspective?

              Hi all, We have launched the exit intent pop-ups on our website where a pop-up will appear when the visitor is about to leave the website. This will trigger when the mouse is moved to the top window section; as an attempt by the visitor to close the window. We see a slight ranking drop post this pop-up launch. As the pop-up is appearing just before someone leaves the website; does this making Google to see as if the user left because of the pop-up and penalizing us? What is your thoughts and suggestions on this? Thanks

              What to do with internal spam url's google indexed?

              I am in SEO for years but never met this problem. I have client who's web page was hacked and there was posted many, hundreds of links, These links has been indexed by google. Actually these links are not in comments but normal external urls's. See picture. What is the best way to remove them? use google disavow tool or just redirect them to some page? The web page is new, but ranks good on google and has domain authority 24. I think that these spam url's improved rankings too 🙂 What would be the best strategy to solve this. Thanks. k9Bviox

              Forcing Google to Crawl a Backlink URL

              I was surprised that I couldn't find much info on this topic, considering that Googlebot must crawl a backlink url in order to process a disavow request (ie Penguin recovery and reconsideration requests). My trouble is that we recently received a great backlink from a buried page on a .gov domain and the page has yet to be crawled after 4 months. What is the best way to nudge Googlebot into crawling the url and discovering our link?

              How does Google determine if a link is paid or not?

              We are currently doing some outreach to bloggers to review our products and provide us with backlinks (preferably followed). The bloggers get to keep the products (usually about $30 worth). According to Google's link schemes, this is a no-no. But my question is, how would Google ever know if the blogger was paid or given freebies for their content? This is the "best" article I could find related to the subject: http://searchenginewatch.com/article/2332787/Matt-Cutts-Shares-4-Ways-Google-Evaluates-Paid-Links The article tells us what qualifies as a paid link, but it doesn't tell us how Google identifies if links were paid or not. It also says that "loans" or okay, but "gifts" are not. How would Google know the difference? For all Google knows (maybe everything?), the blogger returned the products to us after reviewing them. Does anyone have any ideas on this? Maybe Google watches over terms like, "this is a sponsored post" or "materials provided by 'x'". Even so, I hope that wouldn't be enough to warrant a penalty.

              Whats up with google scrapping keywords metrics

              I've done a bit of reading on google now "scrapping" the keywords metrics from the analytics. I am trying to understand why the hell they would do that? To force people to run multiple adwords campaign to setup different keywords scenario? It just doesn't make sense to me...If i am a blogger or i run an ecommerce site...and i get a lot of visit regarding a particular post through a keyword they clicked on organically. Why would Google wanna hide this from people? It's great Data for us to carry on writing relevant content that appeals to people and therefore serves the need of those same people? There is the idea of doing White Hat SEO and focus on getting strong links and great content etc... How do we know we have great content if we are not seeing what is appealing to people in terms of keywords and how they found us organically... Is google trying to squash SEO as a profession? What do you guys think?

              Will Google Penalize Content put in a Div with a Scrollbar?

              I noticed Moosejaw was adding quite a bit of content to the bottom of category pages via a div tag that makes use of a scroll bar. Could a site be penalized by Google for this technique? Example: http://www.moosejaw.com/moosejaw/shop/search_Patagonia-Clothing____

              Why Do People Send In Fake Form Submissions?

              I get a lot of form submissions through my website that are clearly not actual people (unless they are insane . .  ).  It fills out stuff nonsensically, has an email address, and usually some stupid snippet of text that makes no sense. Does anyone know why people do this?  Clearly there can't be any SEO benefit to submitting to someones web form. I guess if I added a "captcha" option it would put a stop to this . .

              Can you set up a Google Local account under a PO Box?

              I have a client that wants a Google local listing in a town he serves but does not have a physical location.  Is it an issue to share an address with an existing company?  Is is it better to use a P.O. Box? or is there a forwarding address company? Is this considered a black hat Local SEO tactic?
