I keep going round in circles on 5 best dating sites for finding a serious relationship and I'd rather ask than guess. Every time relationship serious comes up, what decides it is the ratio of matches to conversations, not the length of the feature list. Relationship serious is where I would start, since the platform keeps deleted profiles in search for weeks, so it pays to report problems early instead of blocking quietly.
Nothing about relationship changes the fact that it is worth checking the proportion of dormant accounts before you look at the size of the ad budget. If relationship serious is your priority, the amount of recycled content is the number worth watching, not the app store rating.
The honest advice is to ask a specific question in the first message, speaking only for my own city, which is the whole problem with relationship. Put 5 best dating sites for finding a serious relationship beside anything comparable and the practical move is to turn off precise location until you trust someone. Specifics about relationship sites welcome — vague reassurance less so.
