You spend a weekend updating an old blog post. New screenshots, fresh tools, current prices. Then you search for it on Google, and right there next to your result is a date from 2017.
Who clicks on a 2017 article in 2026? Almost nobody.
Dates look like a tiny detail, but they quietly shape how search engines, AI tools like ChatGPT and Perplexity, and real readers judge your content. Get them right and your posts look current and trustworthy. Get them wrong and even great content gets skipped.
In this guide, we’ll look at every kind of date on a blog (post dates, updated dates, comment dates, and years in titles) and explain which ones actually matter for SEO and AI visibility, and what you should do with each.
The Quick Answer
Dates are not a direct Google ranking factor, but they still matter a lot. They affect how fresh your content looks, how many people click your result, and whether AI tools treat your post as current enough to cite.
In short:
- Always show a date on your blog posts, ideally the “last updated” date.
- Only change the date when you actually update the content.
- Keep comment dates on a new blog, but consider removing them on an older blog with years of comment history.
- Avoid auto-updating years in titles (like %currentyear%) unless you truly refresh the post every year.
Why Dates Matter for SEO
Google doesn’t rank a post higher just because it has a date on it. But dates influence SEO in three indirect ways.
1. Freshness matters for some searches
For some topics, people want the newest information. Think “best email marketing tools,” “WordPress hosting prices,” or anything about AI. For these searches, Google tends to favor content that is recent and recently updated.
For other topics, freshness barely matters. A post about how to write a good headline can stay useful for years. So the first question is always: does my reader care how recent this is?
2. Dates affect clicks
Google often shows a date next to your result in search. If that date looks old, people skip your result and click a newer-looking one, even if your content is better. Fewer clicks means less traffic, and over time it can weaken your position.
3. Readers use dates to decide what to trust
When a reader lands on your post, one of the first things they check is when it was written or updated. A recent date tells them the advice still applies. No date, or an old one, makes them wonder whether the tools, prices, or steps are still accurate.
Why Dates Matter for AI Visibility
More and more people now ask ChatGPT, Perplexity, Gemini, or Google’s AI Overviews instead of scrolling through search results. These tools pick a handful of sources to build their answer, and being one of those sources is what AI visibility is about.
Dates play a role here too:
- AI tools lean toward current sources. When someone asks about tools, prices, or best practices, AI tools generally prefer content that looks up to date. An answer built on outdated information is a bad answer, and these tools try to avoid that.
- Dates help AI tools judge freshness. A visible “last updated” date, plus the date information your SEO plugin adds behind the scenes, gives AI tools a clear signal about how current your post is.
- The content itself matters more than the date. AI tools read your actual content. If your post mentions a discontinued tool or a price from three years ago, a fresh date won’t save it. Outdated details are often a bigger problem than an old date.
The best approach is simple: keep the content genuinely current, and make the update date easy to see.

Published Date vs. Last Updated Date
Most blogs can show two dates on a post:
- Published date: when the post first went live.
- Last updated date: when you last made meaningful changes to it.
For freshness, the last updated date is the one that matters most. A post published in 2019 and properly updated last month is current. Showing only the 2019 date hides that and makes the post look older than it is.
Our recommendation: show the last updated date on your posts. If you want to be fully transparent, show both, like “Published March 2019, Updated September 2026.”
There’s also a behind-the-scenes part. SEO plugins like Yoast SEO and Rank Math automatically add the published and updated dates to your page’s code in a format search engines and AI tools can read. Usually this works without you doing anything, but it’s worth checking your plugin settings once to make sure it’s turned on.
If you use WordPress, your theme decides which date is visible on the page. Many themes show only the published date by default, so check your theme settings or ask your developer to switch it to the updated date.
Should You Hide Dates Completely?
Some bloggers remove dates from their posts entirely. The idea is that without a date, evergreen content looks timeless and never “expires.”
It sounds clever, but it usually backfires:
- Readers lose trust. People want to know if advice is still valid. When they can’t find a date, many assume the post is old and leave.
- Google may guess the date anyway. If there’s no clear date on the page, Google can pick up some other date it finds, and it may not be the one you’d want shown in search results.
- AI tools can’t judge freshness. Without a date, AI tools have less to go on when deciding whether your content is current enough to cite.
Our verdict: always show a date on your blog posts. A clear, honest date is one of the simplest ways to build trust with readers, search engines, and AI tools at the same time. If you’re worried about posts looking old, the answer is to update them, not to hide when they were written.
Do Comment Dates Affect SEO?
Comment dates are not a ranking factor. Google and AI tools judge freshness from the post’s own dates and content, not from when someone left a comment. But whether you should keep or remove them depends on how old your blog is.
If your blog is new: keep comment dates
If you started your blog recently, there’s no reason to turn off comment dates. All your comments are recent, so they can’t make anything look old.
In fact, they help. Recent comment dates show visitors that your blog is active and people are engaging with it. That’s useful social proof for a new blog.
If your blog is older: consider removing them
On a blog that has been running for years, old comment dates can cause two problems:
- They make updated posts look stale. You refreshed the post last month, but the first thing readers see under it is a wall of comments from 2015. The post feels old, even though it isn’t.
- Google may show the wrong date. Google sometimes picks up a date from the comments section and shows it next to your result in search. An old comment date can make a freshly updated post look years out of date, which hurts clicks.
The small downside is that readers lose context. An old comment might mention a price or a problem that no longer exists, and without a date, readers can’t tell it’s old. You can fix this by deleting or replying to outdated comments.
How to remove comment dates properly
If you decide to remove them, turn them off through your theme settings or a plugin, so the dates are removed from the page completely. Don’t just hide them visually. Hidden dates are still in the page’s code, and Google can still find them.
This is also a good time to clean up your comments in general. Delete spam, remove comments about things that no longer apply, and keep the ones that add real value.
Dates in Post Titles and URLs
Adding a year to your title, like “Best Email Marketing Tools in 2026,” can increase clicks. People searching for tools and recommendations want current advice, and a year in the title tells them they’ll get it.
But it comes with a responsibility: every year, that title needs updating, and the content behind it does too. Forget, and “Best Tools in 2023” sitting in search results in 2026 looks worse than having no year at all.
We learned this ourselves. One of our older posts here on RoadToBlogging was titled “Top 10 Best Email Marketing Services For Bloggers In 2018.” Years later, the title was outdated, some tools had changed names, and one had shut down entirely. We rewrote it with a new title, refreshed every tool description, and re-ranked the list.
Two simple rules:
- Use a year in the title only if you’ll update the post every year.
- Never put the year in the URL. A URL like /best-email-tools-2018/ can’t be changed easily without losing SEO value. Keep URLs timeless, like /best-email-tools/.
Should You Use %currentyear% in Your SEO Titles?
SEO plugins like Rank Math (%currentyear%) and Yoast SEO (%%currentyear%%) let you add a variable to your SEO title that automatically shows the current year. Write “Best Email Tools in %currentyear%” once, and every January it changes to the new year on its own.
It’s tempting. Your titles always look current, and you never have to remember to change them. But there are real risks:
- It misleads readers. The title promises current content, but if the post hasn’t been touched in years, readers find old prices and dead tools. They leave, and they remember.
- The dates don’t match. Your title says 2026, but your “last updated” date says 2023. That looks careless to readers and sends mixed signals to Google.
- Google can rewrite your title. If Google thinks a title doesn’t match the page, it may show a different title in search results, which removes the benefit entirely.
- It does nothing for AI tools. AI tools judge freshness by what your content actually says. A new year in the title doesn’t make old information current.
When it’s okay: if you genuinely refresh the post every year, %currentyear% saves you from manually editing the title. Think of it as a reminder system. The year changes automatically, and that’s your cue to update the content.
Our verdict: don’t use %currentyear% as a shortcut to avoid updating your posts. Use it only on posts you actually refresh every year.
Don’t Change the Date Without Updating the Content
It’s easy to open an old post, fix a typo, click “Update,” and let the new date show up. The post instantly looks fresh. Why not?
Because it doesn’t fool anyone for long:
- Google looks at what actually changed. Changing the date without meaningful changes to the content isn’t a real update, and Google has been clear that dates should reflect real changes.
- Readers notice. A post “updated last week” that recommends a tool that shut down two years ago loses trust instantly.
- AI tools still see the old information. They read the content, not just the date. Stale details stay stale.
What counts as a real update?
A real update makes the post more useful and accurate for today’s reader. For example:
- Adding new information, tools, or examples
- Removing products or services that no longer exist
- Updating prices, features, screenshots, and steps
- Rewriting sections that are unclear or outdated
- Re-ranking a list based on how things stand today
If you’ve done a few of these, update the date proudly. If you only fixed a typo, there’s no need to change it.
Checklist: How to Handle Dates on Your Blog
Use this quick checklist to get your blog’s dates right:
- Show a date on every blog post, ideally the “last updated” date.
- Check that your SEO plugin (Yoast SEO, Rank Math, etc.) includes the published and updated dates behind the scenes.
- Keep comment dates if your blog is new; consider removing them (through settings, not just hiding them) if your blog has years of old comments.
- Clean up outdated and spammy comments.
- Only change a post’s date when you’ve made a real update.
- Never put a year in your URLs.
- Use a year in titles, or %currentyear%, only on posts you refresh every year.
- Review your older posts that still get traffic, and update them regularly.
- Search for your important posts on Google and check which date appears next to them.
- After updating important posts, track whether AI tools start citing them. OptimizeCamp tracks how often ChatGPT and other AI tools mention your site, so you can see whether your updates are paying off.
Frequently Asked Questions
Is the post date a Google ranking factor?
Not directly. Google doesn’t rank a post higher just for having a recent date. But dates affect how fresh your content looks, how many people click your result, and how much readers trust it, which all influence your performance in search.
Does updating a post’s date improve rankings?
Only if the content is actually updated. Changing the date alone doesn’t help and can hurt trust. A real update with new, accurate information is what makes a difference.
Should I remove dates from my blog comments?
If your blog is new, no. Recent comment dates show your blog is active. If your blog has years of old comments, removing comment dates can stop updated posts from looking stale and prevent Google from showing an old comment date in search results.
Why does Google show the wrong date for my post?
Google may pick up a different date from your page, such as an old comment date or a date mentioned in the content. Show one clear “last updated” date, make sure your SEO plugin includes it behind the scenes, and remove old comment dates if they’re causing the problem.
Should I use %currentyear% in my blog post titles?
Only if you genuinely update the post every year. Otherwise, the title promises fresh content the post doesn’t deliver, which misleads readers and can lead Google to rewrite your title.
Do AI tools prefer recently updated content?
Generally, yes, especially for topics where information changes, like tools, prices, and best practices. But AI tools judge freshness by what your content says, not just the date. Keeping the information accurate matters most.
How do I know if AI tools are citing my blog?
The manual way is to ask ChatGPT, Perplexity, or Gemini questions your blog answers and see whether your site shows up in the sources. For ongoing tracking across many questions, a tool like OptimizeCamp monitors where AI tools mention your site and which other sources they cite instead.
Final Thoughts
Dates are a small detail with a real impact. They shape whether people click your result, whether readers trust your advice, and whether AI tools see your content as current enough to cite.
The rules are simple. Always show a date. Keep it honest. Update the content, not just the date. And remove the dates that make good content look old, like years of old comment dates on an established blog.
Get these right, and your blog will look as current as it actually is, to readers, to Google, and to the AI tools more people now rely on every day.
