Amid the increasingly crowded space of social media and social commerce businesses, what does it take to stay on top and stand out in the tech startup arena ? Brand loyalty and exclusive products, said one Silicon Valley executive in a CNBC interview.
Easier said than done when consumers troll the internet for the best price or the latest social media platform to interact with friends or spy on ex-significant others.
Sites like Facebook, Twitter and Pinterest typically see a huge spike in interest at first, but then the core usage began to drop off after one to three years as the power users tend to dominate the conversation, said Michael Fertik, the CEO and founder of Reputation.com, a site that aims to protect digital privacy .
"I think it's happening on Facebook," Fertik said. "I think it's happening on Tumblr. I think it's happening on all the comparable sites because there's no loyalty to one particular place until you have a reason to be there."
"Unless you're somehow in love with it as kind of moms at home are and as kind of kids tend to be for a while, there's no reason to stick around for more than a few years in a very deeply embedded way," he added.
Fertik told CNBC's "Squawk Box" that online gaming lacks stickiness and forecast that gaming giant Zynga is doomed unless it becomes a gambling company.
On the internet, brand loyalty is very weak, he added.
"Nobody cares deeply about Gilt Groupe or deeply about One King's Lane or deeply about Rent the Runway," he said. "What they want is a product at a low price. And that's what the promise of these companies is - to give you the product at a low price."

This means that price-motivated consumers are going to scour the net for the vendor with the lowest prices and the aggregator of this information is the one who wins. If social commerce companies do not have exclusive inventory, they typically only end up with around 18 months of margin retention until margin collapse occurs."
"And that's why any, I think, fundamentally market-making company like a Gilt, like a One King's Lane or like a Airbnb or a VRBO, unless they can get exclusive inventory - meaning only you can get it there - I think they're going to have margin compression over time," he said.
Despite Fertik's concern about some tech sites, he sees opportunity for hard technology that is difficult to replicate.
"I think there are some other great companies that are doing things around lenses and optics and other kinds of analytics at massive scale, huge data sets that are being analyzed," he said.
Amazon and its CEO, Jeff Bezos, also drew praise from Fertik.
"Besos is amazing and I think one of the things that he's doing to maintain a competitive edge is he's putting an enormous warehouse with all the stuff that you want to buy next to your house so that he can deliver it to you in 40 minutes and that's going to be an enormous non-commodity differeniator," he said.
