Two-thirds of top-50 law firms have a Twitter account, but some may be 'damaging their brand’ by failing to actually tweet anything, a report has suggested.

The study by web consultancy Intendance found that 66% of firms had set up at least one account on Twitter. However, of the 48 accounts, 19 had issued no tweets at all, despite some having hundreds of followers.

Intendance said the figures suggested 'many firms have simply jumped on the social media bandwagon without putting much thought into how to use Twitter to their advantage. By neglecting potential followers, those with dormant accounts could even be damaging their brand’. It added that failing to tweet once an account was set up was akin to 'inviting friends to your new flat, and not having any furniture or decorations’.

The study found that the best law firm Twitter account belonged to magic circle firm Allen & Overy, followed by City and national firms DLA Piper and Eversheds.
