I know some bloggers don’t like to update old posts (they like to let them stand as a record of their thoughts at any given point in time) but I personally don’t have an issue with it at all and think it’s a worthwhile thing to do on a number of fronts:
1. Accuracy – there are some times when things you’ve written are simply not true – or cease to be true. Correcting mistakes or making updates to reflect new circumstances actually makes your blog more useful for readers surfing through your archives – which all goes to help improving your blog.
2. Change of Opinion – there are times when over time I change my opinion on different topics. While an old post that you no longer agree with might make interesting reading – it can also impact your reputation. Someone coming to that post won’t know you’ve changed your opinion and will assume that you still think what you once did unless they find something that points them to your new opinion. At times this can be quite damaging to your reputation.
3. Usefulness and Usability – sometimes information in old posts can simply become dated or even ‘broken’ (ie links no longer working as other sites die). Updating these posts with current information and fixing links (either by updating or deleting) makes your post more useful.
By no means am I arguing that bloggers update all of their old posts – but it does make sense to go back through key posts in your archives to do some updating – particularly those that continue to generate traffic over time.
How to Update Old Posts
There are a variety of ways of updating old posts:
1. Quick Fixes – in many circumstances it’s as simple as replacing a link, fixing a mistake etc. In these cases I rarely make a note of it being an updated post as I don’t think it really impacts readers to know that it has been changed.
2. Updates – you’ll see in the example above that I did two things. Firstly I added a number of paragraphs midway through the article. I made the subheading of that section quite clear that it was an update. Secondly I made a note early in the post saying that it had been updated. I wanted to do this at the top of the post to show readers that the information in it was still current. I didn’t want people to see the 2006 date and think it was not valid any more.
When you do these updates that are more than cosmetic (and where you think the information is important) – it can be worthwhile making a short post about it on your blog to indicate to current readers that the post is updated.
3. Reposting – on my photography blog I will regularly take old posts, update the information and then repost them with the current date. I can do this on that blog because the permalinks on that blog don’t include the date in them (as they do here on ProBlogger) and so reposting them doesn’t break the links.
4. New Posts – the last technique that I use is to write a new updated post and then link to it in an old post. I do this when the updated information is significant and warrants a completely new post. In these new posts you may wish to refer back to the old post (so readers can see how your ideas have developed). It is well worthwhile when writing a new post on a topic you’ve covered previously to add a link to the old post to direct readers to the new one so that they get the up to date information.
