Why is this store getting hurt in SERPs when they removed duplicate content?
-
I work with an e-commerce client who got hit hard by Panda. They are very cautious, and want small-scale tests to prove each hypothesis before committing to larger changes.
Recently, we reworked content on 30 product detail pages. Before, these product pages featured some original content mixed with some manufacturer content. The change we made was to remove the manufacturer content completely from the product page, leaving about 300 words of high-quality, original content--all of which was written by subject matter experts.
I assumed that Google viewed this manufacturer text as duplicate content. However, when these 30 modified pages were compared to the control, they performed significantly worse.
Question 1: Does any have any idea why these pages would perform worse than the control?
Question 2: Do you have any tips for convincing this client to try another test or get the buy-in to make the larger changes that--in theory--need to happen?FWIW, this client has about 10,000 product detail pages--the vast majority of which contain just manufacturer content.
I appreciate your thoughts.

I would be curious to look at each form of the pages using the LDA tool.
The main reason to use the tool is to understand if you are significantly reducing the page's relevancy to your target keyword(s).

Hi Ryan,
Thank you for your thoughtful reply.
We didn't make any changes to any of the titles or any overall site changes. We measured the changes using internal tracking tools to get the daily traffic by search engine to each product detail page. We also used Google Webmaster Tools to estimate SERP positional data.
The updated pages do have about half as many total words as the control, so that could definitely explain it.
For followup testing, I'm thinking of trying:
- test versus control, same word count, test is 100% original, control is 0% original
- test versus control, same word count, test is 50% original, control is 0% original
- test versus control, same word count, test is 25% original, control is 0% original

Hi Sarah.
I can't blame the client for wanting small tests. It's actually a prudent strategy.
I think having some manufacturer content mixed in with other quality content is fine. Normally 300 words would be a bit thin but for product pages that is not bad at all.
What changes to the page were made other then the content? Did the title change at all?
How exactly are you measuring the performance of these pages. Please provide as much detail as possible.
Is there any other site wide changes being made at the same time?
Does any have any idea why these pages would perform worse than the control?
Assuming there are no other factors involved, which is a big assumption, the only logical response I can offer is the revised pages are viewed by Google as weaker. By removing the manufacturer's content the pages are thinner and less relevant to the keywords involved.
Do you have any tips for convincing this client to try another test or get the buy-in to make the larger changes that--in theory--need to happen?
How to restore a client's confidence after making an error?
Assure the client you realize they are highly dependent upon their rankings for sales. You are proceeding under your experiences and knowledge, which has been successful in the past. Panda is a new thing and Google is still making rolling out new changes. The industry is still learning and adjusting to these changes. You are consulting with others regarding the unexpected results and you are committed to ensuring this project is properly completed.

Similar Content
I'm in the process of launching two new websites (redesign / rebrand) - one website represents the manufacturer while a second website represents the retail side of the manufacturer (same company essentially but two different brands). The sites have co-existed historically without worry of canibalizing the other's traffic, but I want to make sure in this redesign that we're all set. I'm curious if anyone has any recommendations on how to handle two sites with different branding but VERY similar content (product descriptions are essentially the same). I was thinking it could be smart to just no follow the content on the manufacturers site since we're just trying to drive traffic to the consumer-facing retail side mostly anyway but would love to hear from the experts! Thank you.

Is there a way to automate finding low quality content on your site?
Hi all, I have a site that was once #1 for many keywords. Fast forward a number of years and I am sinking lower and lower and it really started to sink low from September 2012 and appears to be due to an algo update. How should I go about finding my low quality pages? I am told that I might have pages bringing my entire site down. I deleted heaps of low quality pages but not seeing any improvements (might be a little impatient). Any tips for finding bad content?

Promoting blog content
I've created a pinterest board, which kind of serves as a blog also as it tells people how they can save money on their heating bills this winter. Does anyone have any suggestions on how to promote it as a backlinking opportunity? Would it be good to also feature the content on our website? Guest blogging? Any suggestions would be welcomed. Thank you.

Panda and Thin Content
Hi Guys, I have a quick question. We have a website and in the wake of Panda, we are worried about our video news section. We produce about 10 videos news a month on a templated page and beneath it is a small extract of the words spoken in the video. The text below each video is about 180 words each. Currently the video news section makes up and 1/5 of the content on the site. I.e Out of 500 pages, we have about 100 video news articles. Should I be worried about being wacked by Panda for this? Can I tell Google this is a news section?

Press Releases and Duplicate Content on Event Related Site
I have a site that lists events. I ask those submitting events to submit original content if possible, but frequently they submit press releases which are already published elsewhere. I rewrite some of the press releases, but do not have time to rewrite every press release that comes my way. I want my users to get a comprehensive list of events, but I don't want get a penalty for duplicate content. What is the best solution?
