Keep in mind that the age of a blog post doesn't necessarily indicate that it could benefit from an upgrade. Older posts can sometimes continue to do very well (especially if they are a form of evergreen content), and they may not require changes or additions. A careful review of your older blog posts will reveal if an update is even necessary. Use these criteria to decide if a blog post needs to be updated:
Is The Post Performing Poorly In Google’s Search Results?
Check to see how your blog posts are ranking on Google. If you wrote an article that doesn't show up until page 10 on Google's SERP, it's not doing well. Evaluate the post to determine why its ranking is so low, especially if it was performing better when it was initially published. It may be because it's no longer relevant to your target audience or needs updated optimization. Whatever the cause might be, a low ranking article is worth revisiting to see if you can improve its standing on Google's search engine.
Is The Post Getting Any Traction On Social Media?
Social signals are vital to your blog post's performance as well. When a blog article is liked or shared on social media, then it has successfully engaged readers. If your content isn't getting any kind of social media traction, then the article may need to be updated. An update is especially necessary if the post isn't receiving social engagement despite ranking well on Google, which could indicate that readers don't find the content helpful enough to endorse.
Does The Post Have Poor Google Analytics Metrics?
Using analytics, you can monitor the performance of your posts over time. Specific metrics can indicate whether an article is doing well or not, despite social signals or page rankings. For example, if a post's time-on-page metric is extremely low, it may mean that visitors aren't even bothering to finish reading your content. If the click-through-rate is poor, it may indicate that readers were unsatisfied with your content or that your call-to-action was weak. Poor metrics suggest that something needs to be changed, and they can help point you to precisely what needs to be updated.
Is The Post Performing Well For The Wrong Reasons?
When evaluating the performance of an old blog post, you might find some conflicting information. For example, you may find that an article is ranking well on Google, but your metrics indicate that it's doing poorly. Such a contradiction can occur if Google is ranking your article for something other than the intended topic and is attracting the wrong audience for your blog post. Updating the content will ensure that you're attracting the right audience. Otherwise, the traffic you're generating won’t do you much good.
Could The Post Be Doing Better?
In some cases, you might find that an article isn't doing that bad; however, you may have had high hopes for that article. The content may have been a long-form, detailed exploration of a topic you consider yourself an authority. If this is the case, don't just write it off as having set your expectations too high.
The Post Is Ranking On The Second Or Third Page
A blog post that ranks on the second or third page of Google isn't ideal. Most users won't go past the first page of Google. However, if your post is ranking on the first or second page for a popular or broad term, then it's worth revisiting your content to see if you can push it over the line. After all, ranking that high for a commonly used keyword is a minor feat in itself.
The Post Is Attracting Google Traffic But Has Poor Analytics Metrics
Attracting lots of traffic but having weak metrics doesn't necessarily mean that Google is ranking it for the wrong reasons or that visitors don't like your content. There could simply be a different issue with your content that's resulting in poor metrics. For example, maybe your post is missing a call-to-action, which is why it's not converting well. Or perhaps there are no internal links, which means most visitors are leaving your website after reading your article.
