How to Catch Someone Cheating Online (Legally & Secretly)

It’s perfectly normal wanting to know if your significant other is still faithful, especially when you notice something’s changed between both of you.

If you’re looking for a way to quickly find out if your partner is cheating on you, you’re in the right place. In this post, we’ll show you several ways to get the answers easily and secretly.

Signs your spouse might be cheating on you

We don’t become paranoid all of a sudden. Normally we’d start suspecting when we smell something fishy. So here’re some behaviors that might indicate something is not right. You should be extra careful when you notice one of these signs.

  • “Working late”/”out with friends” more often
  • Avoiding intimacy
  • Unexplained expenses
  • Spending more time on phone
  • Sudden changes in daily schedule

These are just some of the “bad signs”. But still, they don’t mean anything. And remember suspicion doesn’t justify illegal actions, so don’t do anything that might jeopardize your relationship, such as bugging phones, using AirTag to stalk your partner, etc. If you want to discover the truth, there’re some methods that are more practical.

How to find out if someone is cheating online

When you notice changes between you two, instead of guessing and praying, you need to empower yourself and get to the bottom of it. If you don’t know what to do next, here’s how you can start digging.

Find traces from social media interactions

If your partner is actively on social media (Facebook, Twitter, Instagram, etc.), you might want to start there looking for clues. You can look through Likes, Comments and new followers, as these are common metrics that might give out information of the suspect.

For example, if you find an account that’s secretly following your other half and liking every single post, you can dig deeper and look up the owner and past interactions. It’s also a smart move to cross-reference the username on other platforms or dating apps (Tinder, OkCupid, Hinge, etc) to find out who’s the secret follower.

But to catch a cheater, these are not enough.

Get solid proof with people search engines

To have more confidence in your situation, you need some solid proof. If you’re wondering if your partner is hiding something, it’s necessary that you do some digging.

Dig up secret dating profile

We all have our secrets. And smart cheaters might have a secret life they don’t want you to know about. To find out if your significant other is secretly seeing someone, you need a powerful tool like Spokeo.

Spokeo is a people intelligence service that features a database of over 12 billion records. With Spokeo, in less than a minute you’ll be able to view all the pics and profiles on social media of a person, including accounts on dating sites.

  1. Go to the Spokeo search page. Enter the name or phone number and click SEARCH NOW.
  2. In a few minutes, you can see all the social media accounts associated with the name or number.

Look up strange contact

If you’ve noticed a strange number that’s been calling frequently, you can do a quick search to find out the caller, location, social media accounts and more.

This requires a professional search engine, and Peoplefinders might just be the perfect choice for this job. With a huge database, Peoplefinders allows you to secretly dig out everything about a name, a phone number or an email address.

Note that Peoplefinders is a subscription-based service, so you need a membership to access the report. If you’re not a member yet, the good news is that PeopleFinders is now offering a special deal of $0.95 for the first report.
