The Internet giant has been pushing its survey products to the staffers and operatives who work for presidential and congressional campaigns, as well as the journalists who cover them.

"As we started to get ready for the 2016 cycle, that's when things really started to pick up a bit on my side," said Karen Sheldon, a Google veteran who is an account executive on the sales team for the product, known as Google Consumer Surveys.

Sheldon has been on the road promoting the new product at Republican primary debates co-sponsored by the company. She has also appeared at conferences featuring polling experts.

At least one presidential campaign found Google's pitch attractive enough to put a poll in the field using the tool, the company said, while declining to name the candidate.

Google has also stepped up its outreach to reporters and editors covering the election, giving them free credits to run surveys of their own. The company launched a website in January to explain the service to journalists and let them access data from polls created by Google's team.
