How to Update Old Blog Posts Instead of Writing New Ones

Many small business blogs keep publishing new posts while older ones slowly become outdated. Refreshing an existing post is often faster than writing a new one, and the page already has history, links and indexed status. This guide shows how to choose which posts to update, what to change, when to merge or remove posts, and how to handle dates honestly.

Find candidates in Search Console

1. Open Performance → Search results and set the date range to the last 12 months with Compare to the previous 12 months (or compare recent 3 months with the same 3 months last year for seasonal topics).
2. Open the Pages tab and sort by click difference. Pages that lost clicks are candidates.
3. Also look for pages with many impressions but a low CTR, or average positions around 8–20. Our guide to the Performance report explains these filters.
4. Add any posts you know contain outdated facts, prices, screenshots or regulations, even if traffic looks stable.

Decide: update, merge or remove

Merging is the usual fix for cannibalization, where several of your pages compete for one query. Redirect rules are covered in our migration and redirects guide.

What to change in an update

• Facts and figures. Replace outdated statistics, prices, laws and product details. Cite the current source.
• Search intent. Search the main query and look at what ranks now. If results have shifted from long guides to quick checklists (or vice versa), adapt the format.
• Missing questions. Use the Queries tab for the page to find questions people search that the post does not answer, and add sections for them.
• First-hand detail. Add examples, photos and steps from your own work; this is what makes a page more helpful than generic content.
• Title and description. Update them to reflect the improved page; see writing titles and descriptions.
• Internal links. Link to newer related posts and service pages, and add links from newer posts back to this one.
• Images. Replace outdated screenshots and compress large images.

Handling dates honestly

Showing a recent “updated” date tells readers the content is current, but only change it when you made a meaningful update to the content. Changing the date on an unchanged post, or after fixing a typo, misleads readers. Google’s guidance on dates recommends showing a clear date and keeping it consistent with your structured data (datePublished, dateModified).

• Keep the original publication date, and add “Updated on” with the new date for substantial changes.
• Update dateModified in your Article markup and the lastmod value in your sitemap only for meaningful changes.

A worked example

Illustrative example: a home-services company has a 2023 post, “Water heater replacement cost”. Search Console shows it lost clicks, and its prices are two years old. The update:

1. Replaces prices with the company’s current typical ranges, labelled as typical and dated.
2. Adds a section on tankless options because the Queries tab shows searches for it.
3. Merges a thin 2024 post, “Signs your water heater is failing”, into a new section and 301-redirects that URL.
4. Adds two photos from recent installs and links to the water heater service page.
5. Updates the title, adds “Updated November 2026”, and updates dateModified.

After publishing

• Use URL Inspection in Search Console and request indexing for the updated URL.
• Note the date of the update and compare performance after 4–8 weeks against an equal period before.
• Keep a simple refresh log so you know what changed and when.

A good rhythm for small teams is to refresh one or two existing posts for every few new ones. For choosing new topics, see how to find SEO blog topics customers actually search for.
