The report on the conference season, created by MHP with digital monitoring tool Synthesio, compared the level of debate across all social media platforms, including Twitter, blogs and forums for all three conferences, the leaders and specific policy areas.
It also analysed the top ten political blogs that have driven conversation at conference.
The Conservative Party conference generated 59 per cent of the conversation on Twitter about the conferences, with 22 per cent about Labour and 19 per cent about the Liberal Democrats.
The report found that only the Lib Dems saw a net positive sentiment online, with 63 per cent of opinions positive, and that Nick Clegg was the only leader who saw a spike in his personal net positive sentiment score during his speech.
David Cameron attracted more interest on social media than the other leaders, with 60 per cent of the conversation referring to him. The leaders dominated traffic, with all three attracting more interest than their cabinet and shadow cabinet colleagues.
The Guardian website dominated conversation about conferences across all political blog and comment websites, the report found.
MHP Communications acting head of public affairs Nick Laitner said: "This report gives an overview of the opportunities digital engagement offers us and represents a growing trend across all areas of business and communications.
"I think it is fascinating to see that Nick Clegg was the only party leader who saw a spike in his approval ratings. Equally, despite Labour managing to take the headlines during conference season, it is interesting to see that this was not reflected in the share of voice or sentiment shown towards the party. This shows that the online debate doesn’t necessarily track the offline consensus, making engagement across all channels all the more important."
