I've seen a lot of posts on this forum where hosts are upset about receiving a four star overall review when the guest has given them five stars in every category. Those reviews/ratings look something like this:
There is no explanation given in the feedback or review as to what they were unhappy with and they have marked each category with five stars, so what on earth was the problem? The problem is that they have NOT given five stars in every category. When a guest reviews, it is totally optional to fill in the star categories. They can rate some, all or none of them. Many guests choose to rate none and just give an overall rating (as in the example above). When this happens, all the categories will show up as five stars under that review in your Progress tab, but they do not count as five star ratings, i.e. your percentages in each category will neither go up nor down.
How do I know this? Because I keep track of my overall and individual star ratings (you can see these percentages under each listing in your Progress tab), so I can see each time a guest reviews which categories, if any, they have rated. Here's an example.
This is not fail safe as how much the percentages go up or down with each rating depends on how many reviews you have for that listing. If you only have ten, each rating can be worth 10%, whereas if you have 100, it would only be worth 1%. If you have over 100 reviews, you might not always see a change in the stats with each guest that rates. Still, you can get an idea overall if guests are rating the individual categories or not.
Of course, I shouldn't need to keep a log of these percentages. The stars under each review should only show what the guest has actually given, not show five stars for a rating that doesn't even exist. It is obviously causing confusion amongst hosts and Airbnb needs to change this, but I thought I would shed some light on it, so that next time you see that four star rating with five stars in each category, it is not so confusing.
