Plenty of Fish's algorithm favors people who are online now or were active recently. It learns from how much you interact with the people it shows you and with the app itself, and it uses your stated preferences and the people you like, including people it sees as likely to be interested in you too. POF also describes subscribing or buying Boosts as a way to skip the line.

Show up while people are online

POF gives weight to people who are online now or were active a short while ago. For you, that means being on the app regularly counts for more than being on it for a long time.

A man who opens the app for fifteen minutes every evening keeps showing up as recently active. A man who spends three hours on it one Sunday and then disappears for a week spends most of that week looking like somebody who has gone quiet.

a dating coach says much the same about dating apps generally. A little every day earns you more than a lot all at once, both from the women and from the software deciding who to show you. He points out that the first half hour you spend on a given day is worth far more than the sixth. So make it a short daily habit, ideally in the evening or whenever the women near you tend to be scrolling, and the recency part of the algorithm works in your favor without any extra effort.

It learns from how you use the app

POF says the algorithm learns from how much you interact with the people it shows you and with the app as a whole. Your behavior is information, whether you mean it to be or not.

That is a good reason to be deliberate. Like the women you would actually want to meet, and write to the ones whose pages give you something to say. My view of most apps is that liking everyone does you no favors. An app that sees you like everyone learns nothing about your taste, and it has little reason to show you the women you would have picked.

Being selective does not mean being stingy. It means your likes and your messages point in a consistent direction, so what the app learns from you is accurate.

Your preferences and likes set the direction

The algorithm also uses your stated preferences and the people you like. Between them, those two decide the pool it draws from.

Set your preferences honestly. If they are much narrower than what you would really date, you shrink your own pool for no reason. If they are much wider, the app fills your screen with women you will pass on, and you spend your fifteen minutes scrolling instead of talking.

Then let your likes refine it. Each one tells the app a little more about what you are looking for, which is another reason to like with some thought.

It looks for interest going both ways

POF says it recommends people who have a high chance of reciprocal interest. In plain terms, it tries to show you women who might like you back.

That changes how you should think about who you like. A like on a woman who might plausibly like you back is not settling. It is putting your effort where a conversation can actually start. You still aim high, but you aim at women who fit the life your photos show.

It also means your own page matters to what you see. The better your page does with the women you like, the more the app has to work with when it looks for mutual interest.

Paying to skip the line

POF describes a subscription or a Boost as a way to skip the line. Either one gets you seen sooner than you otherwise would be.

My rule for any paid feature is that it multiplies whatever you are already getting. If your page earns some likes and replies for free, paying can earn you more of them, and it is often worth testing. If your page earns almost nothing, a Boost puts that same page in front of more women who pass on it. A multiplier applied to zero is still zero.

coach also has a view on timing, drawn from his experience on several apps. A Boost earns the most after a break, when few people have seen you recently. Stack Boosts close together and the returns shrink, since fewer of the people online near you are seeing you for the first time.

So try one, compare the result against an ordinary evening, and keep paying only if it clearly beat it.

What the algorithm cannot do for you

The algorithm controls who sees you. Whether they like what they see is out of its hands.

That part is down to your photos and your first message. A lead photo where she can see your face properly, well lit and without friends crowding it, decides whether a woman stops scrolling. A short first message about something specific on her page decides whether she answers.

Get those two right and every part of the algorithm above starts paying off. Get them wrong and no amount of activity, selectivity or Boosting will fix the result.
