Squiz Matrix we have now started a nine month project to clean up the content we currently have in whichever system it is sitting in. In total we have over 10,000 pages to work our way through so although 9 months sounds like a long time it really isn't!
The best possible outcome would be for us to close around 15-20% of the current pages, fix all the broken links and spelling mistakes and make the migration of content as easy as possible. Realistically though this is probably not going to happen...
People become very attached to their content, the value the time they have put into creating it and don't really want that to be taken away. A fair position to take if you only look at the time spent putting the content together but not if you look at the wider picture. If no-one has viewed the content then can it be said that it adds value to the website or visitor experience? I'd argue that it does't and that the content should be removed. It's easy to highlight what should be closed with a simple analytics report, the clever part is in convincing people it's the right decision!
So, we are now 3 weeks into a nine month project and so far it's going reasonably well, pages are being closed, we're using Siteimprove to find and fix broken links and spelling mistakes and hopefully the quality of the site is improving on a daily basis. But, we're only just getting started so who knows what the next few months will hold for us!
PS. The image is of the Edit+ editing tool within Squiz Matrix, a far better editing environment than the ones we currently use... roll on next year!
