The parties are using data and targeted digital ads as never before as we enter the home straight in this General Election.
Hundreds of voters across the county have participated in Sky News' Invisible Election Project seeking to understand how - and by who - "dark ads" that are not normally visible elsewhere are being used.
As Sky News reported earlier, the targeting of social media adverts and the use of data are now a huge part of election campaigning, but have limited or even no regulation from the Election Commission.
Hundreds of responses from Sky News viewers reveal the online battle.
The Conservatives are currently blanketing the internet, particularly sites such as YouTube, with video adverts, such as attack ads on Jeremy Corbyn and Diane Abbott.
The targeted effort began early in the campaign with two sets of letters, apparently sent and digitally signed by the Prime Minister, aimed at postal voters.
