I wrote last June about the disappointing show from the main political parties as far as social media was concerned. Back then, I also suggested that this coming election could see social media playing an important role in the campaign mix.

With election campaigns getting under way I still believe this. If only the political parties did.

It’s not that they’re ignoring social media but at the moment it’s all a bit style over substance.

They appear to be falling into the trap currently occupied by a lot of businesses and organisations who have also “done” social media in recent times but not really got anywhere with it.

The problem is that like others who complain that social media isn’t working, they are focusing more on the channel rather than REALLY thinking about the content.

A common problem with a lot of social media marketing at the moment is that there is too much focus on the channel – the technology and the means of distribution like Facebook, Twitter, iPhone app and so on.

This is probably because the very genre is defined by the channel – the media.

Which is why a lot of organisations think they’ve “done” social media just because they have a Twitter account or an iPhone app.

But the channel is only a conduit. It’s what is sent and distributed via that channel that holds the key to success. Content, purpose, targeting and resource must be well planned to maximise engagement.

For example, last week the Tory party launched its very own Conservative Party iPhone app.

So cool.

Well actually not quite so much. It’s really a mini-brochure with a few little questionable tools built in, like its swing-o-meter showing election results as they come in. Which will be useful for about 12 hours tops on the night.

The detail on its policies is informative but it’s basically their manifesto in condensed, digital format. For more comment, read Mobsessed’s opinion about the Tory app, it’s good stuff.

And this week we saw the launch of the Labour Party’s social media campaign.

This is much more interesting, using opinions expressed through social media and on the doorstep to “inform” their social media activity. I have no idea what “inform” actually means here though. There’s no clue as to what they will do with all this content.

They’ve also given social media training to key campaign staff. The problem again is that it all feels very token-like. Time will tell.

It’s not all negative. There are some great examples of local and national party activists, party members, MP’s and councillors who really do understand it.

But so far no party has an obvious centralised social media strategy bringing together and mobilising all campaigners to truly listen to and engage with the public and key influencers.

What I’m really talking about here is online PR, and as far as I can see it’s here they are missing an opportunity.

Where is their online PR strategy? How are they creating and resourcing active social media engagement on a daily basis with online citizens: individuals, communities, influencers, bloggers, tweeters, publications and so on?

I can’t see any of that happening on a scale akin to Obama in the US for example.

Maybe it’s coming, or already happening. But I can’t see it, which kind of defeats the purpose.

Online PR is a great way of approaching the task in hand because it diverts attention from the channel, Twitter, the iPhone app or whatever to the meat of the matter – the content, community engagement and the direct conversation.

When the main parties get their head around the fact that this is what social media is about then they may see some success from it in terms of influencing opinion and voting intention.

As things stand, the general public are likely to see through token gestures and do what they normally do when it comes to politics – switch off.

Just as it should in other areas of politics, with social media it’s substance, not style, which holds the key to success.
