If you follow the sidebar advice about lifting and raising SMV, as well as apply basic picture-taking advice, then eventually you will start getting a ton of matches via online apps. Your issue will then shift from getting matches in the first place to filtering for who is actually interested.

What I hate more than anything is being some chick's backup option or meeting a girl with "meh" interest level. I find it much more difficult to bang these girls, and the dates usually aren't that much fun, either. The best and easiest sex is with girls who are truly excited to meet and fuck you.

One simple interest gauge that I use is the call to action. Not only does it filter for compliance, but it can also spark what is known as the "Ben Franklin effect".

My own bio includes the following:

Tell me a fun fact.

That's it. If she sends some generic message like "hello" and ignores my call to action, that's usually a good sign that the interaction won't go anywhere. She either doesn't care that much about impressing me or is too stupid to think of a fun fact. I don't have patience for dumb broads like this.

On the other hand, if she actually does tell me a fun fact, it shows a minimal level of investment and compliance. If she's interested enough to engage the higher-order cognitive process necessary to conjure a "fun fact," then you know that your chances of passing through the three remaining resistance barriers (phone number, date, intimacy) are fairly high.

Of course, the call to action should ideally reflect some quality that you value. I prefer girls with a modicum of intelligence, so the fun fact shtick works well for me. If you want fit chicks, try something like "how much do you squat?" If you want adventurous girls, "favorite travel spot" could work.

Moreover, the very act of doing you this "favor" can actually cause her to like you more. People don't do favors for people that they like; rather, they like them because they do favors for them.

Benjamin Franklin, himself an apex Alpha/legendary chick magnet, noted this phenomenon over 200 years ago:

With sites such as Tinder, you will still be expected to open most of the time, so this advice isn't as useful there. Still, I have a nearly 100% track record of success with girls who do open me, so take that for what it's worth.

On Bumble, though, where women have to send the first message, the call to action is much more relevant as a filter. Ironically, the app that markets itself as women-centric is actually the best tool for high value men to determine who is serious about meeting. Typically girls on Bumble are only going to open their top prospects, and you can use compliance as a secondary test for seriousness.
