Some quick thoughts:

Depending on the audience demographics, contact marketing team of top dating apps in your target countries (probably US and India) like Tinder, Badoo,etc.. and make custom deals to feature them. Negotiate a base monthly subscription + performance deal.

Have a look at https://advertise.buzzfeed.com, apply to their program pretending to be a large brand or new startup with series B/C funding and attend their sales call, they have the exact same business model.

Look online at Casper's strategy regarding SEO, they ended up acquiring the review website for mattresses that brought them seo traffic.

Ideally you could negotiate an exit strategy to one of the dating players if you have a good relationship with their SEO manager.
