Google may be on its way out as the dominant player in search, according to one analyst — and could even "disappear" in as little as five to eight years if the competitive pressures that ultimately claimed other search giants start to take root.

In the wake of a surprisingly weak earnings report, Eric Jackson, Ironfire capital founder and managing member, said Google Google [GOOG 681.79 -13.21 (-1.9%) ] could easily find itself fending off the woes that eventually took hold at embattled Yahoo! [YHOO 15.84 -0.16 (-1%) ].

"They could disappear in five to eight years and disappear in the sense that Yahoo used to be the king of search. Now, for all intents and purposes, Yahoo has disappeared," Jackson said Thursday on CNBC's "Squawk on the Street".

The primary reason Google may lose its search dominance is because the company is facing the same mobile problem as Facebook [FB 19.00 0.025 (+0.13%) ], Jackson said. (Read More: Google Has the Same Mobile-Ad Problem as Facebook)

"If Facebook saw a deceleration in their sales and their growth lead to a halving of their stock price...why wouldn't it also be something that is very negative for Google as it continues to play out?" he said.

Google reported in its quarterly earnings, which were released Wednesday, that its cost per click (CPC) was down 15 percent in the third quarter.

While the company reported that ad sales had increased, it is likely that CPCs will continue to decrease, Jackson said.

The reason? Consumers are searching more and more on mobile devices, yet advertisers aren't as willing to buy advertisements formatted for mobile devices, because these ads are not as prominently displayed.

Also, mobile ads tend to run more cheaply than ads made for desktop computers.
