Any solo matchmaking tips?

It helps if you accept that your teammates are likely going to be bad. Try to focus on your gameplay and how you have fun. Having fun doesn't necessarily have to be winning and being able to differentiate fun and winning will help you enjoy the game more.

Otherwise, I would recommend SWF. If you had a good game with a couple randoms just add them. Even without coms, having reliable players will make your games more fun.

Solo que is where all the challenging fun is. If teammates are that bad, use builds to capitalize on them. I usually run a savior build as if I was in swf and make bank off of their failures or a stalker build so I can keep eyes on where the killers at and lead/assist the team in avoiding. Doing this has occasionally brought out the best in random teammates.

If you want good teammates, queue up as killer.

play out any perk that make you strong how a rock

1. If you're not a strong looper, run Spine Chill. Every time it lights up, stealth towards the direction you think the killer is coming from. Hide behind the environment while doing so they don't see you. 9 times out of 10, they don't expect you to sneak past them in the direction they're coming.
2. If you're on PC and have cross-play enabled, know that most console survivors are selfish and will leave you to die during end game. So it is best for you to try to avoid the killer at all costs when the last gen pops. Don't waste your time looking for NOED or trying to save, let them die unless you choose to run borrowed time and you yourself are good at looping and making the killer miss.
3. Plunderers is underrated. It doesn't always give you what you want, but it is a good way to get a key during a crappy match. Even if you don't get a key, regardless of what the forum says, the tool boxes that you get will help you finish the gen during a clutch moment. Green and Purple med-kits help a lot too.
4. Don't run Kindred. It is useful if you have competent teammates but you will probably go bald from all the hair you pull out from aggravation of watching your teammates hide around the hook, not doing anything other then let the hook timer get shorter. I have had so many teammates see that the killer is camping and the gens progression just comes to a standstill and just make it easier for the camper.
5. Iron Will is good if you're decent at losing the killer. I put it on par to Calm Spirit for average, casual players. Calm Spirit is really good verses Doctor, Iron Maiden and Infectious Fright (which is really strong on instant-down killers).
6. If you want to practice and gain experience looping, I suggest you try to find the killer at the start of the match. By the end of the match you will find that your teammates used up all the pallets and everywhere you go is a dead zone.
7. Always take a med-kit, especially if you don't run Self-Care. Lots of people look down on SC because it is so slow and can cost the game if used at the wrong time, but sometimes you just need to heal and you'll regret not running it, so Med-Kits are a must if you're not running Plunderers. Inner Strength is a good alternative to SC. The only drawback is you have to find a totem to make it work.
8. Always try to do the gens that are bunched up close to the center. This prevents your team from 3-genning yourselves. Doing the central gens will force the killer to walk further in order to patrol the last few gens, giving you time to work on them. It really sucks if the last gen is right next to two others, especially against Doctor or other high mobility killers.
9. If you are against Trapper, Bubba or Hag, stay away from the basement. If Trapper has the add on that causes disarming traps to hurt you, don't even attempt to rescue anyone in the basement unless they were a really good teammate. If Bubba is camping, just rush gens. If its Hag, you have a chance if you run Borrowed Time, otherwise, most people just cry.
10. DS is really only good if you have competent teammates that will take hits for you. I wouldn't run it solo. You're better off running Dead Hard or another exhaustion perk like Sprint Burst or Lithe to help you get away from a camping/tunneling killer.

I find survivor most fun when I am playing in a duo, which is way easier to put together than a full 4-man SWF. If I'm playing DBD alone, I'm usually playing killer.

With soloq. It can be hard mode for sure. Some helpful builds that help with me looping

fixated/sprint burst/iron will/windows

this can be fun to use and also let you know when your teammates take all the pallets. The downside to this is no one brings an obsession perks.

thus my backup build is the meta

iron will/dh/ds/ub

I hate using this build but I’m back in red ranks and after a while it makes more sense to use.

my fave build to use regularly is

resilience/spine chill/quick and quiet and lithe

Here's the best tip I've found: Longer Queue Times = Worse Matchmaking. Play in times where you find matches quickly and you will be more likely to get better teams.

I started to play killer and it helped. So when you see survivors doing dumb #########, it always works in your favor.
