***A Message from Brian Burke – A Look at Detailed Seller Ratings Data & Other Feedback News***
October 10, 2007 | 01:59PM PST/PT

Hi everyone – this is Brian Burke from the Trust & Safety Feedback team. It's been about six months since we began introducing Detailed Seller Ratings (DSRs), and I felt it was time to provide a brief update to let you know more about the progress and results we're seeing with DSR data.
DSR adoption rates
We're delighted that buyers are leaving detailed seller ratings over 72% of the time. In some countries, such as Australia, daily adoption rates are above 80%. In addition, the overall rate of Feedback being left remains at 70%. This is a positive result, because it shows that the introduction of DSRs has not had any negative impact on buyers' willingness to leave Feedback.
A look at marketplace DSR scores
With over six months of data, the DSR scores for eBay.com are showing some healthy early patterns. Our data proves the vast majority of our sellers perform well in satisfying their buyers.
Below is a table with a breakdown of DSR scores by seller percentile. The median score reflects the score that a seller in the middle would get, if sellers were ranked by their buyers from best to worst. As you can see, scores are 4.8 for most categories and 4.6 for shipping costs.
Bottom 10% of Sellers | Bottom 25% of Sellers | Median Seller | Top 25% of Sellers | Top 10% of Sellers | |
---|---|---|---|---|---|
Item as Described | 4.6 | 4.7 | 4.8 | 4.9 | 5.0 |
Communication | 4.5 | 4.7 | 4.8 | 4.9 | 4.9 |
Shipping Time | 4.3 | 4.6 | 4.8 | 4.9 | 4.9 |
S&H Charge | 4.3 | 4.5 | 4.6 | 4.8 | 4.8 |
Using DSRs
Detailed Seller Ratings are a measurement of buyer satisfaction, and they give sellers a tool they can use to evaluate how they are performing. When an individual set of DSRs (visible to sellers by mousing over the stars in their profile) is compared with the chart above, sellers can get a sense of how well they are performing compared to the marketplace as a whole. Sellers with scores lower than the median can take advantage of this data – which is provided by buyers across the marketplace - to reevaluate and adjust their business practices.
As we look to ensure that buyers have great experiences on eBay, we will be leveraging this DSR data in several ways in 2008: to help us evaluate seller performance, to determine PowerSeller eligibility and the benefits associated with the PowerSeller Program, and to influence priority in search results.
Other Feedback news – Removing Item Title from Buyer Profile page
Last spring, the inclusion of the item title on the "Feedback as a Buyer" page brought immediate controversy. Buyers viewed this as an invasion of privacy, even though this information is readily available through advanced search. Sellers complained because they feared buyers would not bid/buy, since no other e-commerce site includes buyer purchase history so prevalently.
We surveyed buyers and over a third of them were concerned or extremely concerned with the visibility of this information on the "Feedback as a Buyer" page. So, effective today, we will be removing the item title from this page.
You'll be hearing more about the use of DSRs in the future, so please stay tuned.
Sincerely,
Brian Burke
Director, Global Feedback Policy

***Update on Feedback: Detailed Seller Ratings***
10 October, 2007 | 10:04PM BST
We are pleased to provide a brief update on the Detailed Seller Ratings (DSRs) introduced about 6 months ago.
DSR adoption rates
We’re delighted that buyers are leaving detailed seller ratings over 78% of the time. In addition, the overall rate of Feedback being left remains at 70%. This is a positive result, because it shows that the introduction of DSRs has not had any negative impact on buyers’ willingness to leave Feedback.

DSR figures to affect search results.
[email protected] 15-10-07 18:23 BST 134 of 193
Evening everyone,
Thanks for your comments on this thread, which is being read with great interest.
We set up feedback mechanisms for buyers and sellers to use as they see fit. We didn't rig the original feedback system so that the 98% of sellers scored over 98% - that's just how it turned out. Nor did we rig the new detailed system so that so many 5-star ratings would be handed out - that's just how it turned out.
For the most part, these high scores reflect the simple fact that sellers on eBay largely do an excellent job and please buyers in most transactions. That's great, and we're not about to intervene in the system to push buyers to score sellers more harshly or less harshly. It is what it is, and sellers have an equal chance of benefiting or suffering from this (or almost any) system and the way that buyers use it.
We will move gingerly into advantaging and disadvantaging certain sellers based on these DSRs, with small-scale testing to understand exactly the effect that they have when factored into search results ranking.
However, we are very clear we are not serving our buyers well if we allow the small group of sellers who fall into the bottom couple of percentiles of scores on postage costs, or postage speed, or communication, or accuracy of description to have the same level of visibility and access to buyers as other sellers do.
Cheers
Richard
PS Ebays hampster driven techies have problems getting the basics right so what makes you think they can manage anything so sophisticated?
This sort of witless and casually insulting comment will only lead to other points that you make being discarded or ignored. Please refrain from talking about eBay staff like this - it hardly fosters a productive and positive atmosphere for communication.

Pinks, a question re the details seller ratings
[email protected] 24-10-07 18:34 BST 50 of 92
Evening all,
The point of any rating system is that it offers a spread. In the case of the DSRs, the spread may be small, but there's a spread nonetheless (and I think it'll widen a little as buyers get used to the anonymity of DSRs). There are still sellers who are 'among the best' in particular areas, and sellers who are 'among the worst'. The fact that the gap between 'best' and 'worst' may only be 0.5 points is somewhat irrelevant - it still represents many more buyers expressing their dissatisfaction.
So, given that we have ways of identifying sellers who are 'worst' and 'best' that are consistent and fair in aggregate, why shouldn't we use them to penalise the 'worst' and advantage the 'best'. If you administer a marketplace, as we do, then you're in the business of improving things for buyers by improving things for good sellers.
What those penalties and advantages will be is currently subject to testing. But to close with the favourite statement of totalitarian regimes everywhere: 'those who have nothing to hide have nothing to fear'.
Cheers
Richard

Using Detailed Seller Ratings in search
[email protected] 13-11-07 09:18 GMT
Good morning Powersellers,
I wanted to sound you out about something that's currently under discussion at eBay Towers - 'excessive shipping'.
We know from our analysis of detailed seller ratings that, for any given rating, only 1-2% of sellers have an average score below 4.0 (I'd rather the spread was larger, but there you go). In the case of the 'postage & packing charges' DSR, these 1-2% of sellers in turn account for about a third of buyer complaints.
So, we're thinking of taking dramatic action against them. In particular, we're considering changing the way that search results are sorted so that listings from sellers with a P&P DSR below 4.0 always appear at the bottom of the page.
What do you think of this? Harsh? Fair? Workable? Unworkable? I'd be grateful to hear your views.
Cheers
Richard

Just one note from me at this point: in proposing 4.0 as a cut-off I'm including only the bottom 1-2% of sellers.
Those sellers are the bottom 1-2% for a reason - not because the odd buyer is harsh in their assessment, but because they are systematically gouging on postage costs.
Yes, of course you get the odd buyer who gives a '4' even when postage is free, but such things affect all sellers equally. Here we're talking about the bottom 1-2% of sellers relative to all other sellers. These are the bad apples, not innocent victims of mean buyers.
Cheers
Richard

***Clamping Down on Unfair Postage & Packaging Charges***
05 December, 2007 | 04:20PM GMT
We pride ourselves on bringing sellers a large audience of engaged, active buyers. In the last month alone, almost 15 million people visited eBay.co.uk looking for great deals on all manner of items.
Over the last year we’ve been asking those buyers who have left eBay, or who no longer buy as much as they used to, why they did so. One of the most common reasons cited was the prominence of sellers who clearly overcharge for postage & packaging on their items.
The introduction of Detailed Seller Ratings on the site earlier this year allows us to identify clearly those sellers who are consistently rated poorly by buyers for postage & packaging charges. As a result, we’ll shortly be introducing changes to the way that we display search results based on Detailed Seller Ratings for postage & packaging charges.
For the vast majority of sellers, this will mean that your items will continue to be featured as normal in search results.
However, those sellers who consistently receive the lowest scores on postage & packaging costs will receive considerably reduced visibility in default search results by appearing much further down the list of items. This will apply to sellers whose Detailed Seller Ratings for postage & packaging are 3.9 or below, which accounts for roughly 0.5% of all sellers on the site.
This small group of sellers are responsible for a hugely disproportionate number of buyer complaints about overcharging for postage & packaging, and taint the vast majority of good sellers who buyers agree are charging fairly.
We will be introducing these changes during the week beginning December 17th, after the main Christmas trading period is over, and we encourage all sellers to continue to review their postage and packaging charges to make sure these are as fairly priced as possible.
We expect to make further changes to the display of search results to protect buyers in 2008, including extending the use of Detailed Seller Ratings to other areas of concern for buyers.
You can comment on and ask questions about this change here.
Regards,
The eBay Team

eBay to clamp down on Excessive P&P
[email protected] 07-12-07 17:50 GMT 48 of 56
Thanks for the comments, everyone - a breath of fresh air and reason. Sorry I haven't posted on the topic here.
There are about 25 UK Powersellers affected by this - most of you are well clear of the threshold and will always be so even if we tweak it up a little in the future.

eBay are going to hate this
Nonsense, we love it. Anything that gets big sellers to focus more on their DSRs is a pretty good thing by us.
If a rating of 4.91 puts you in the top 10%, 4.90% in the top quartile and 4.89% shoves you back down to the medium 50% THIS IS NOT MEANINGFUL DATA.
Just because the spread isn't huge isn't the same thing as saying that differences in ratings aren't statistically significant. With the number of ratings that Powersellers get, over time the relative distribution between you and your fellow sellers is pretty fair, IMHO.
And we're very comfortable with implementing a system of penalties (and rewards...) based on the aggregated opinions of your buyers. And if you're focused on customer service and respect your buyers, so should you be.
Cheers
Richard

***Clamping Down on Unfair Postage & Packaging Charges: First Phase Now Live***
20 December, 2007 | 10:51AM GMT
We announced a couple of weeks ago that we would be significantly reducing the visibility of listings from sellers with very low Detailed Seller Ratings (DSRs) for postage & packaging.
We are pleased to announce that this change is now live. From now on, all listings from sellers with a DSR for postage and packaging of 3.9 or lower will be displayed at the bottom of search results, below listings from all other sellers.
This affects a tiny minority - roughly 0.5% - of all sellers on the site. All other sellers will be unaffected by this change.
We are introducing this change as a first step towards curbing excessive postage and packaging charges on the site. These excessive charges deter buyers from continuing to make their purchases on eBay, and harm the success of the vast majority of good sellers on the site.
We encourage all sellers to review their DSRs regularly and to ensure that their postage and packaging is fairly priced.
We plan to make further changes to the display of search results to protect buyers during 2008, including extending the use of Detailed Seller Ratings to other areas of concern for buyers, and we will announce these in due course.
Regards,
The eBay Team

Clamping down on unfair P&P charges: Comments now it's live
[email protected] 20-12-07 11:55 GMT
Morning everyone,
This change is now live. I've locked the second 'Day 2' thread on this topic, and will keep it pinned for a while so that those who want to can read and refer to it.
I'd be grateful for your comments on the changes to search results now that they're live. Searching for 'Buddha' in Antiques is one way to see them in action (though you may need to clear cookies first).
I stress that we're focusing only on the exorbitant P&P over-chargers, but also that this is just a first step, with more to come in 2008.
Best regards
Richard

Because eBAY seems set on dealing with the bottom 5% (not 10%) I would like them to show us the star number of that bottom 5 -- I am guessing it will be mid 3's at best --
I have tried making this same point, but mostly been ignored. Maybe you'll have better luck.
The problem is, people are making an ASSUMPTION that has never been proven. Mathematically, just as there is a top ten percent, there is a bottom ten percent. that's just math, nothing more.
What IMPORTANCE to attach to the bottom ten percent is for eBay to decide.
People are ASSUMING that ebay has decided that those in the bottom 10% will be in some way disadvantaged by eBay. And there's no question that eBay has indicated that DSL will be used in some fashion. ebay has been clear on that.
But NOWHERE has eBay said the cutoff point will be at TEN percent.
People are ASSUMING that is the cutoff point, but I defy anyone to show me where eBay has stated that.
I believe eBay may use the bottom 5 per cent, or even lower. And as you note, that would , of mathematical necessity, mean a lower DSR than the bottom ten percent DSR figure.
So the problem here is people are making a totally unwarranted ASSUMPTION about the EFFECT of being in the bottom ten percent.

Thank you Carl....I just tried making this same point in another DSR thread. I've said over and over again, ever since the DSR "Chart" was provided, that we should not ASSUME that those particular tiers have anything to do with disadvantaging sellers. ebay could have chosen ten tiers to show us, or fifty , or whatever.
That chart had one purpose only: to give us all some idea of where we stand relative to other sellers.
At no time did ebay EVER say that THOSE five tiers were the tiers ebay was going to use to determine disadvantaging.
I think Wingo is doing the seller community a disservice by claiming that the tiers have any real relevance to the issue of disadvantaging. he is making the same unwarranted assumption so many here have been making, and he really should know better.

linda,
Yes, ebay said it would use DSRs in determining search placement. I'm not disputing that.
But NO ebay did not say THOSE FIVE TIERS would be used.
You are making an ASSUMPTION.
Look, there are two separate things here.
The problem is, people are looking at that chart eBay provided, and pointing to the bottom 10 or even 25% and ASSUMING that one or both of those tiers will be disadvantaged.
To put it another way: eBay said it would use the DSR stars, but it did NOT say it would use the five tiers shown in the chart.
You are not wrong to say that eBay will use DSR, but you are wrong when you say that it will be the bottom ten percent that will be disadvantaged.....ebay said it will use the DSrs, but it did not say anything about what the cutoff point would be.
As I've said, we have one announcement from eBay, in the UK, and that does NOT use the bottom 10%...it uses the bottom .5%.
Really, I wish ebay had never posted that chart, because so many people...including Wingo....have made the totally unwarranted assumption that those five tiers have some great significance in terms of disadvantaging sellers. But they don't.
People are getting alarmed about this when there's no need to be: "Oh my, what if I fall into the bottom ten per cent? I'll be disadvantaged!!!!"
We don't have a shred of evidence to support the idea that the bottom ten per cent is the group that will be disadvantaged.

With eBay poised to begin favoring higher-rated sellers in search results, it appears many of its highest-volume sellers will soon get reduced exposure on the site.
More alarmist speculation from Ina Steiner, without any basis in fact.

minny:
What you are referring to is the one actual announcement eBay has made so far in terms of actually implementing a policy that disadvantages sellers in terms of search results.
That was in the UK, and it has to do with the S&H rating. To fall into the disadvantaged category, a seller has to have a 3.9 or less, and, according to ebay, only the lowest one half of the lowest one per cent of sellers fits into that category.
Here's the announcement:
http://www2.ebay.com/aw/uk/200712201050062.html
In other words, in the one instance in which we actually KNOW what cut off point eBay is using, it's not----as some keep insisting, contrary to all evidence---the lowest 25% or lowest 10%, it's the lowest one half percent.
Now, let's see a show of hands....how many posters here are really in any danger of being in the bottom one half of one percent of all ebay sellers?
"None" is my guess.
For the umpteenth time: ebay provided the chart to let us know how we compare to other sellers. eBay has NEVER said that any particular chart percentile will have any particular consequence (such as the bottom 10% will be disadvantaged) I've been pointing this out since the chart was first published. yes, ebay said DSRs will be used in the future, but eBay did NOT say anything about the particular divisions shown on the chart.

cumos,
Can you please show me an actual statement from ebay that says eBay intends to advantage the top 10% in search results?
I've never seen such a statement.
I've seen plenty of people saying that, just as plenty of people have been saying that the bottom 10 or 25% will be disadvantaged,a statement for which there is no proof.
Yes, eBay has indicated some sellers may be advantaged in search results....but precisely how, or just what cut off point ebay will use....as far as I know, ebay has said nothing about that.
