First of all, I would like to apologize for posting late. I had hoped to publish this thread before SLD but it was not until yesterday that I had some free time to work on it. Please get yourself a cup of coffee / tea or whatever you like best before starting to read this post, this time it will be a little long.
The first topic of this series was about how to calculate the amount of x* rated orders that would impact the rating causing it to lose points, this one is its complement and like the other, it’s not aimed to tell sellers what to do; it’s just intended to be an easy and understandable explanation on how to calculate amount of orders needed.
Structured slightly different, quick calculation tables will help this time to calculate the amount of x* rated orders for maintaining / gaining rating but, as opposed to the first topic where the given values were for not falling beyond 0.1 points, the ones given here reflect the amount of orders required for maintaining the actual rating and/or gaining points.
As we all know, rating is cumulative, it doesn’t disappear from sellers’ history - remaining through life for calculation purposes - and since it is an average value, it is always calculated from the very first rated order up to the moment of its evaluation (rated orders deleted by Fiverr, obviously don’t count). Therefore, whatever rating shown in the profile, it is the overall rating or as Fiverr calls it, “All-Time Rating”.
It should also be noted that rating shown by Fiverr is rounded to 1 decimal digit, which means that every number within a 0.099 interval will be expressed as X.Y (e.g., [4.855 - 4.954] will be rounded to 4.9) - rounding, by the way, that doesn’t tell much about how close anyone is to either edge. This point seems just as a math explanation but it’s not if Fiverr takes into account this range of values when calculating the rating, reason why “expanded rating tables” will be incorporated this time.
Likewise, it is important to mention the following about the amount of orders (AO) needed to modify the rating - whether positively or negatively:
- AO is directly proportional to the total amount of reviews, meaning that the greater the amount of reviews, the more new rated orders will be needed to either to fall or jump. In this regard, changes in rating are less drastic as the total amount of reviews increases (See graphs 1 & 2).
- AO is an asymptotic function, making it easier or harder to fall, keep or raise the rating depending on: 1) the proximity of values between the rate of the new orders and the rating to be kept/achieved and 2) the location of the actual rating within the interval - on either edge of any given rating interval, AO tend to behave in a similar way regardless of the amount of reviews (See graphs 3 through 5).
Throughout the graphs, the following statements can be verified:
Less amount of rated orders, bad/good respectively, is requiered for maintaining rating than for gaining it.
Changes in rating are more drastic as the total amount of reviews decreases, thereby, sellers with low amount of reviews can get into trouble very easily.
Flat surfaces might not be as wide as one may think when looking to the 1 decimal digit rating showing in each one’s profile, since the nearer the rating is to the lower edge, the lesser amount of orders it will take to fall. Same happens for gaining points when rating is nearer to the upper edge - lesser amount of orders will be needed to jump.
Amount of rated orders tend to behave in a similar way regardless of the amount of reviews when any given rating is on either edge of the interval.
Once fallen, the easiest way to recover, is by trying to get orders to be rated as far as possible from the actual rating not only because the rate would be higher, but because of being further away from the rating that wants to be raised - the nearer the rate is from the rating, the higher the amount of orders of that specific rate will be needed (asymptotic approximation).
Additionally, for the same reason of being asymptotic, if anyone thinks that jumping straight into 0.2 points is just multiplying by 2 the amount of orders that makes the rating raise 0.1 points, bad news, it’s not. So the best way to climb, is one step at a time and as explained above.
Considering what has been said and the fact that I don’t know Fiverr’s criteria nor the amount of decimal digits involved in calculations, the methodology used will differ this time because it is much more important for values to be as accurate as possible. Likewise, formulas will also be provided.
Things to be taken into account:
Values on the quick calculation table are based assuming Fiverr rounds up with 0.055 (e.g, 4.455 = 4.5) and, although combination of rated orders can also be made, each value was determined taking into consideration only the specific rate as if it were the only one to impact the overall rating.
Values on the expanded rating tables are calculated on a 0.001 step basis and for correcting purposes assuming Fiverr calculates rating with 3 decimal digits before rounding to 1 decimal digit.
Divided into 2 areas, the quick calculation table will serve this time on double purpose: yellow is for maintaining rating and blue is for gaining rating. All values work and can be applied directly for any given amount of reviews, even with small amounts.
Values shown in the quick calculation table are given as a percentage of the total amount of reviews and values shown in the expanded rating tables are just factors by which to multiply depending on the 3 decimal digits rating.
Calculating Actual Rating:
Go to the bottom of your “Analytics” page were it says “Ratings” and multiply each number that appears in parentheses with its corresponding star. Add all the products and divide by the total amount of reviews. Leave the obtained number with the first 3 decimal digits (e.g., 4.464546 = 4.464). That will be your expanded rating.
Finding the amount of rated orders: Using the tables - Methodology
A.- Multiply your total amount of reviews by the corresponding value shown on the quick calculation table.
- Position yourself on the row that corresponds to the 1 digit rating, the whole row will give you the complete range of values: yellow for maintaining and blue for gaining. Intersect with the column corresponding to the rate you’re looking for and multiply the intersection value by the amount of reviews.
B.- Multiply the obtained number by the factor shown on the corresponding expanded rating table and divide by 100.
- Position yourself on the row that corresponds to the 2nd decimal digit rating and intersect with the column corresponding to the last decimal digit rating. Multiply the intersection value (factor) that corresponds, whether for maintaing or gaining, by the number obtained in A and divide by 100.
For Maintaining Rating: Only use the integer part of the number obtained in B (e.g., 49.46 = 49 ; 52.87 = 52).
For Gaining Rating: ADD 1 to the number obtained in B and only use the integer part (e.g., 49.46 = 49 + 1 ; 52.87 = 52 + 1).
Let’s say you have a 4.4 rating and want to know how many 4.8* orders will be needed to pull it up and what would be the maximum amount of 3.5* orders that can be afforded for not dropping.
Rating shown on profile: 4.4*
Reviews: 58 reviews
1.- Calculate your actual rating to 3 decimal digits
Detailed Rating showing on the Analytics page:
((5 * 37) + (9 * 4.4) + (6 * 3.7) + (1.5 * 2) + (1 * 4)) / (37 + 9 + 6 + 2 + 4)
(185 + 42.3 + 18.5 + 3.4 + 5) / 58
254.2 / 58 = 4.38275…
Expanded rating = 4.382
2.- Use the quick calculation table & expanded rating tables
- Maintaining rating: Using the yellow area
A.- Position yourself on the row that corresponds to 4.4 on the quick calculation table, intersect with the 3.5 column and multiply the intersection value by the amount of reviews.
(58 * 5.26) = 305.08
B.- Position yourself on the row that corresponds to 0.080 on the expanded rating table for maintaining rating and intersect with the 0.002 column. Multiply the factor with the value obtained previously and divide by 100. Keep the product and just use the integer part.
(305.08 * 0.602) / 100 = 1.836
Maximum amount of 3.5 * orders for maintaining rating = 1
- Gaining rating: Using the blue area
A.- Position yourself on the row that corresponds to 4.4 on the quick calculation table, intersect with the 4.8 column and multiply the intersection value by the amount of reviews.
(58 * 15.94) = 924.52
B.- Position yourself on the row that corresponds to 0.080 on the expanded rating table for gaining rating and intersect with the 0.002 column. Multiply the factor with the value obtained previously and divide by 100. Add 1 to the product and just use the integer part.
(924.52 * 1.326) / 100 = 12.259
12 + 1 = 13
Minimum amount of 4.8 * orders for gaining raiting = 13
