(CNN) — Their paths crossed on YouTube on an August night last year.

Jeremy and Christy Nueman used YouTube to find their adopted baby, Caleb.

Amanda, a college student seven months pregnant, scrolled past a YouTube video of a young California couple seeking adoption.

The couple, Jeremy and Christy Nueman, wanted to adopt a baby after struggling with infertility for five years. But instead of relying solely on newspaper ads or bulletin board fliers to increase their chances of connecting with a birth mother, they created a short YouTube video to show who they are.

Upon watching the video online, Amanda immediately connected with a snapshot of the Nuemans’ adorable miniature pinscher named Penny. She giggled when she saw video of Jeremy Nueman dancing happily in his kitchen, which reminded her of her own father.

She played the video over and over again.

“The video was comforting, and I could relate to them” said Amanda, who picked the Nuemans to become the adoptive parents of her baby boy out of hundreds of profiles she viewed online and through adoption agencies. Amanda chose to keep her last name anonymous for privacy reasons. “It’s so hard when you are just reading a letter to figure out what are these people like.”

With a high demand for domestic infants, adoption experts say the wait for a baby can be months or years. To gain a competitive edge, a growing number of adoption-minded couples are using Web sites like YouTube and Facebook to sell themselves as parents. Going online is cheaper, faster and reaches a wider audience than using just on print advertisements and word of mouth, they say.

Some wannabe parents are uploading YouTube videos featuring a hodgepodge of photos, home tours and interviews. Others are writing on blogs and personal Web sites to give birth mothers a glimpse of their adoption journey. To help spread the word, prospective parents also are utilizing social networking sites like Twitter, MySpace and Facebook in the hope that their friends may know of a potential birth mom.

“Today’s teens and young adults looking for adoptive parents are more tech savvy than before,” says Jeff Siler, who owns ParentGallery.com, a free site created in 2007 where couples wanting to adopt can post pictures and video online. “Even before teens talk to an adoption agency, they may already be trying to Google for an answer online.”

Social media like YouTube, Twitter and Facebook are also gaining traction among private adoption agencies. Bethany Christian Services, one of the nation’s largest adoption agencies, which completed more than 730 domestic infant adoptions last year, advises its couples — including the Nuemans — to create a YouTube video.
