UNDERSTANDING FEEDBACK SCORES

[bettimoor-0]

I was just curious as to how a seller that has over 20 negative feedbacks in less than a month can still maintain a 86.6 score.

I have 1 negative feedback that is way over 6 months old and my score is only a small notch above this.

Disagreeing with @ebeths_eclectic_collectiblesYour response to the one negative was not unprofessional. It was fine.  It could be improved by speaking to potential buyers, not just speaking to that particular buyer. 

My answer to your question about stability of FB scores would be with this adage: A percentage is indifferent to scale, but change in the percentage is a slave to scale.

A small and larger seller with the same ratio of positive and negative feedback will have the same score. (Contradicting the example by @mam98031  which didn't address the number of feedbacks in the past year; number of transactions is irrelevant.) 

But a small seller feels the impact of a negative more because one is a large share of a small number but a small share of a larger number. Essentially the same as what you were thinking.

I would add the obvious, again contradicting  @ebeths_eclectic_collectibles, sellers who get hundreds of negatives every month still sell here. Sellers with feedback scores below 90% continue to sell here.  eBay doesn't cull bad sellers.

They may charge such sellers more IF their "bad selling" results in a large number of not as described returns.

And apparently consumers are willing to buy from a bad seller. Maybe because the deal is irresistible, and/or they are betting they won't be in the 10% of buyers that had a bad experience.

That buyer cursed me and should have been removed from EBay as a buyer and a seller.

She also got a friend to buy something inexpensive from me and then destroy it upon arrival to give me another negative but after I reported it to EBay they investigated it and removed that feedback.

I found out through that one negative buyer just how really ruthless and cruel people can be on EBay.

If I do something to warrant a negative feedback so be it I can live with it but to intentionally sabotage someone with false accusations is another story all together, I get there are people like that but there is also Karma and it will come back to them one day.

I had 2 choices as far as that negative went and that was to mail the item and get scammed to the tune of about $600 or take a negative and you know which road I took.

I thought I was a little bit nice with my response to her, if it would have been in my younger days when this happened I probably would not still be allowed to sell on here.

That isn't mathematically possible.  The negative FB is divided by the positive feedback, not a "ratio" of those numbers.  You may want to re-read what I posted as I clearly said it covers the past 12 months of numbers.

Let me try this again.  If you go to anyone's FB page and click on the little "i" with a blue circle around it that follows the FB percentage at the top of the page, it will explain how the calculation works.  Here is an example from a how mine reads.

• The positive Feedback percentage is calculated based on the total number of positive and negative Feedback ratings for transactions that ended in the last 12 months, excluding repeat Feedback from the same member for purchases done within the same calendar week (eBay time).
• Note: This could mean that the number of ratings used for this calculation is different from the same number shown in the recent ratings table on the left.
• Positives / (Positives + Negatives)
• This member's 12 month Feedback ratings
• Positives: 277 Negatives: 0
• This member's positive Feedback percentage
• 277 / ( 277 + 0 ) = 100%

I have a lot of repeat customers and unfortunately only about 20% of my buyers actually leave FB.

I know you know what you know. But in your second reply in this thread, you said:

"For example a seller with 20 negatives and 1,000 FB would be an 80% FB rate.  A seller with 20 FB and 10,000 transaction would have a 98% FB rating.  "

You got the result of different FB ratings for small and large sellers because you used the same number of feedback. You referred to "transactions" in the second sentence instead of feedbacks.  One would have to read all of your comments to understand that you meant feedbacks in the past year.

Its okay.  the OP loves you. 🙂

My mistake was I should not have used the word Transaction.  It should have been Feedback.  

I did not use the same number of FB.  20 negatives with 1000 FB is 80% FB rate.  20 negative FB with 10,000 FB is a 98% FB rate.

If you believe that each of these sellers should have the same percentage, then you would be ignoring the fact that they aren't the same size and you can't do that if you want accurate numbers.

It is simple math.  I did mess up the words in the post above but still this is a pretty simple process.  Don't over think it.

• The positive Feedback percentage is calculated based on the total number of positive and negative Feedback ratings for transactions that ended in the last 12 months, excluding repeat Feedback from the same member for purchases done within the same calendar week (eBay time).
• Note: This could mean that the number of ratings used for this calculation is different from the same number shown in the recent ratings table on the left.

• This member's 12 month Feedback ratings
• Positives: 277 Negatives: 0
• This member's positive Feedback percentage
• 277 / ( 277 + 0 ) = 100%

Your math is all off and wrong. 20 Negative FB on a profile with 1,000 total feedback does not equate to 80% and a seller with 20 FB and 10,000 transactions would not have a 98% FB rating.  

You meant to say 200 negative feedbacks, not 20.

20 is 98% of 1,000.

20 is 99.8% of 10,000

200 is 80% of 1000

200 is 98% of 10,000

No, my math was fine.

Look at your FB page and look at how the percentage is calculated.

• The positive Feedback percentage is calculated based on the total number of positive and negative Feedback ratings for transactions that ended in the last 12 months, excluding repeat Feedback from the same member for purchases done within the same calendar week (eBay time).
• Note: This could mean that the number of ratings used for this calculation is different from the same number shown in the recent ratings table on the left.
• Positives / (Positives + Negatives)
• This member's 12 month Feedback ratings
• Positives: 234 Negatives: 1
• This member's positive Feedback percentage
• 234 / ( 234 + 1 ) = 99.6%

This is a very old thread.  It will get closed soon.
