How can I avoid duplicate content when building a review widget?
-
My website has a profile page for each of the home improvement contractors who signs up. They accumulate reviews on those pages. I want to build a review widget to display our reviews on our contractors' websites. How can I avoid duplicate content issues for the reviews?
Example of a profile page with a few reviews: http://www.thehomefixers.com/members/425/waterheaters-plus-llc.php

I think you should use a review aggregator like YotPo. These will deliver reviews to your contractor's sites without duplicating the content because the content won't be in the source code. Any plug in you can design will prevent duplicate content. You will basically display the content without it being in the code. The only HTML the robot will see is the coding for the review system.

Thanks - the problem is that the remainder of the page is also likely to be somewhat duplicate - it's mostly NAP data, business tagline or coupon offers, which are likely to be extremely repetitive as these businesses often have dozens of listings, all with the same info. The reviews are really our only differentiating content from all their other listings.
If the reviews popped up on their sites as well (via our widget) would a link back to their profile page (part of the widget) be enough to indicate to Google that we were the original source? I don't think canonical tags will be an option.

"I want to build a review widget to display our reviews on our contractors' websites."
If you are going to be displaying it as a widget on their website, I'm not sure what duplicate issue you are expecting. You would not have the same reviews across mutiple sites if you are adding contractor-specific reviews to a contractor-specific site. Unless you are referring to having the review content displayed on your siet where they sign up, and also on their site as a widget. Even if that is the case, you will have so many differences between the two pages and surrounding supporting text I doubt you would see any if at all negative effects.
Duplicate content penalties are aimed at people who use multiple pages of exact or highly similar content to try and manipulate search engine rankings. Just by having a few reviews that are the same across a few pages I dont think you would be grouped into that.

Does it apply with content writen about a product, and the description writen inside the product caracteristics in my e-commerce store?
Right now I have the same info in the product info page, and the product in the store...
Should I write different info for both pages?
-
But would I be able to get the canonical tag on the client website via the widget code? Or I'd need two separate code snippets for installation
-
No, it would be for the whole page. It's good practise to have the canonical tag on anyway though
-
Can the canonical tag be applied to only a portion of a page's content? (basically, everything within the review widget?)
-
What percentage of page content would be duplicate?
I am asking because I remember seeing a video of our spiritual guide Matt Cutts addressing that, and he said at google they do understand content sometimes is quoted, cited, etc... And it all depends on how much text is duplicated when you quote, cite...
But unfortunately he was not saying how much is too much.
-
What content is going to be duplicated? The reviews?
The best way would be to add a canonical tag to the website. You need to identify the main page the content is going to be on then add the canonical tag. For example, If you have 4 pages with similar content then pick the page that has more authority and canonicalise the others to that page.
Here's more info on the canonical tag https://support.google.com/webmasters/answer/139066?hl=en

I'm wondering if reviews services like yotpo and reviews.io are worth it.
The reviews services advertise that your reviews and stars will be placed in your Google search results and this helps with rankings. Does anyone have experience using Yotpo or Reviews.io with a brick and mortar business? Or, any business for that matter? Thanks,

Review Schema Dropped Off A Cliff!?
Hello everyone, I recently implemented some review schema for my website which looked to be successful as my review stars were appearing in organic rankings with no problem! Yay! However... I've just checked in on where we are with these and they have literally dropped off a cliff and I have no idea why. See image attached with the graph that shows our reviews looking great in July/August then dropping off w/c 26th August. I literally have no idea why this has happened. The Schema Markup Tool shows no errors or issues with the markup either. Can anyone advise? 81Rv88Y

Any experiences with Reviews.io?
Hello, We have used Trustpilot.com for a few years in the past. Service was reasonable and they did what they were supposed to do. However, due to their price and requirement for a full-year payment upfront we stopped using their review collection service. Is someone using Reviews.io? They are included in Google Review Partners, which seems to be very encouraging:

https://support.google.com/adwords/answer/2375474?hl=en Also, they have a decent price for their intermediary package (about $ 89/month) and don't require a yearly contract like Trustpilot and some others. Any experiences you could share about Reviews.io will be appreciated. Luciano, The Translation Company Group0 -
BazaarVoice Paginated Reviews Not Honoring Canonical & Indexing Multiple Pages
If there are enough reviews on a product page to warrant page 2, 3 etc, BazaarVoice appends the below snippets to each new page of reviews, which are then also indexed, despite BazaarVoice SEO settings that automate a canonical tag (seemingly since the differing reviews on each page are not similar enough to honor the canonical). <cite class="iUh30">?bvstate=pg:2/ct:r</cite> <cite class="iUh30">?bvstate=pg:3/ct:r</cite> It seems Target.com has found a way to hack the BV code to create a dedicated page to view all reviews: https://www.target.com/p/ultra-soft-fitted-sheet-300-thread-count-threshold-153/-/A-13973172?showOnlyReview=true While Ikea.com blocks it in the Robots file (defeats SEO value) - Noindex: */catalog/products/bvroute=Review Noindex: */catalog/products/bvtab Tons of brands apparently have the issue, and you can see more examples if you search "inurl:bvstate=pg" Anyone aware of a solution to this?

3rd Party Approved Reviews - Widget or API Feed - Any thoughts ?
Hi Mozzers, We use a google approved 3rd party review company to collect reviews for our branches and now also for our products( this is about to be implemented). We currently use one of their widgets on our site (its javascript) to show the reviews. I don't think google can read this and I don't think we currently, therefore, get any direct seo benefit from it. My questions are as follows : I obviously want to get any SEO benefit from any review text which customers leave but as the data itself is housed on the review site with a widget on my site pointing to it,should I use an API feed as opposed to a widget. If google can read the review text on my page - then surely i should some benefit from it even though, it could technically be classed as duplicate content what are peoples thoughts ? . thanks Pete

How does decimal rounding of reviews to stars work in ios appstore? Starting from which average review score to get full 5 star rating?
How does decimal rounding of reviews to stars work in ios appstore?

Starting from which average review score to get full 5 star rating? Duolingo has a 5 star rating, but I doubt that they really have an all time review average larger than 4,75. In the google playstore their average of the android version is 4,6. Does anybody know how apple calculates the star ratings or has an URL reference where this is explained?0 -
Moving my photography business to another state. Is it possible to transfer Google My Business listing WITHOUT losing my Google Reviews?
A friend of mine is transitioning her photography business to another state. She moved about 5 years ago and consequently lost all of her Google+/Yelp reviews. Having reviews as a photographer is EXTREMELY important for her business reputation. She doesn't want this to happen again. Is it possible to change the location of a Google my Business page and keep the existing reviews? Thanks

Migrating Reviews from Old SIte
We recently changed our Website to Word Press and I would like to move the old reviews to the new site. I am concerned Google might not understand the reviews showing up all of a sudden. The old reviews were on a sub-domain (store.domain.com). I will be able to match the dates and text as well as names. Any advice or Best Practice on this? Thanks!
