Ranking Score Explained

Hi there, thanks for your interest in how we calculate an experience's ranking score. It's at the core of Rankers so I'm pleased you're curious.

The ranking score percentage is used to compare and sort experiences in ranking tables. It is not necessarily a direct measurement of the quality of a particular experience as rated by its customers. I've found it a useful tool to allow me to find the best experiences with confidence. But I've also found it important to read the customer reviews before making any final judgements!

We calculate an experience's ranking score using a multi-factor data model instead of a raw data average (mean). This model takes into account several important questions. For instance - is there a trusted body of reviews? What is the age of a review and is the review from a credible source?

Below you'll find details around some of the important factors that went into calculating the ranking score for Discover NZ Motorhome Rentals.

If you have any questions or comments about our ranking score calculation please get in touch at info@rankers.co.nz. We don't believe this is perfect or complete so we're always interested in ways we might make improvements.

Weighted Average

95.94%

Rankers calculates a weighted mean as a base average on which we can improve. Individual review's ratings are given a weight based on several factors. The weight of a review determines the overall impact it'll have on the final weighted average.

Recent reviews have more weight as they are more relevant and reflect the experience as it currently operates. Over time reviews become less relevant and loose their impact on the ranking score.

Low rating reviews carry slightly less weight. This dampens the effect of very low ratings for every experience across the board. This is especially important when the experience has few reviews overall and a single negative rating can grossly mischaracterise an experience. Consistent poor reviews will still result in the experience receiving a comparitively low ranking score.

Credible sources provide reviews that can be trusted. If we have verified a reviewer is genuine via a face-to-face meeting then the review carries additional weight.

Adjustments

Several adjustments to the weighted average are added to improve relevancy and credibility. These adjustments apply equally to all experiences that meet the criteria.

Sample Size Adjustment

No Adjustment

A reasonable number of reviews are necessary in order for the average to be credible and for an experience to take a prime position within the ranking tables. As such, experiences with only a few reviews have a moderated score. This does not mean that the experience or the reviews can't be trusted. The Discover NZ Motorhome Rentals experience has plenty of reviews and does not meet the criteria for any adjustment.

Recent Reviews Adjustment

-6.98% Adjustment

Recent reviews reflect the experience as it currently operates. This means it's important to get fresh reviews. Some experiences discovered they could get a few good reviews and then, resting on their laurels, discourage any further reviews. This adjustment stimulates experiences to be positively involved in the review generating process and discourages them from manipulating the ranking system in this manner. There may be an adjustment if an experience hasn't received any reviews within the last 60 days.

The Discover NZ Motorhome Rentals experience has 0 recent rankings. Adjustments are according to the following table:

Recent Reviews Adjustment
0 -3.00%
1 -2.83%
2 -2.33%
3 -1.50%
4 -0.67%
5 -0.17%
6 -0.00%

In addition, an experience's ranking score may be adjusted for each day there is no new ranking. After 1 day the adjustment comes into effect. The maximum number of days that can be adjusted for is 199 days.

The Discover NZ Motorhome Rentals experience has been adjusted for 199 days. Adjustments are according to the following table.

Days Adjustment
196 -3.92%
197 -3.94%
198 -3.96%
199 -3.98%
200 -4.00%
201 -4.02%
