Digital Marketing Update March 2026

Welcome to The Marketing Den’s digital marketing update for March 2026.

We’ve sprung into spring. And I feel like digital has sprung into action too. March has been a busy old month for digital marketing. Here’s everything you need to know:

Search Updates from March 2026

Google Spam update March 2026

Spam updates are algorithm updates designed to penalise websites that violate anti-spam policies.The last spam update was in August 2025 and took 27 days to roll out. This one started on 24 March and was completed within 24 hours. Given the fast turnaround it’s assumed that this was a fairly standard update. It was applied globally and to all languages. The update targeted low‑value content, especially mass AI‑generated stuff.

I don’t think this means, don’t use AI to generate content. But it does mean, don’t use AI on it’s own without adding that bit of human sparkle. Your content must offer value and answer real questions from real people

Google Core update March 2026

Hot on the spam update’s heels, was the Google Core update. This was the big one. One of the most significant ranking updates over recent years, it’s aim is to improve search relevance and content quality. The update had a strong focus on distinguishing between AI assisted content created for humans and AI generated content intended solely for search ranking manipulation.

The combination of these two updates mean that Google now actively penalises sites with mass produced AI content that lacks human insight, originality or value. Metrics like bounce rate, time on page and engagement are now stronger indicators of quality. This means that content with original research and expert commentary will be rewarded with greater visibility.

Search volatility March 2026

With two updates in close succession, you should expect high levels of search volatility. This means you may see sudden drops or sudden rises in rankings. Let things stabilise before making any major decisions.

Structured data support

If you run forums or Q&A pages, Google now has a new structured data property called DigitalSourceType. This allows you to be more transparent about whether or not the content has been created by AI. Through structured data you can indicate whether the content was created by an LLM or an automated reply bot. More info on how to use Google’s structured data markup can be found here.

Analytics Updates from March 2026

Bing offers AI visibility updates

Microsoft has introduced a new AI performance feature within Bing Webmaster Tools. It allows you to track how site content is featured in AI responses (though I think it mainly focusses on citations in Microsoft Copilot and Bing AI summaries). While you can see how often you’re cited, you can’t see how many users have clicked through to your website.

Google Search Console natural language prompts

Google Search Console will now filter data based on natural language prompts. So you simply type what data you want to see. This feels particularly useful for anyone who doesn’t live in the platform day-to-day, making it much easier to find what you need. It’s not yet available for Discover or News reports, just standard search results.

Google Analytics is launching ‘Scenario Planner’ and ‘Projections’

Scenario Planner is a new feature to help cross-channel budgeting, helping advertising planners model different budget allocations across channels and estimating how those changes impact conversions, revenue or ROI. 

On a related note, Projections is a new feature that helps advertisers adjust live campaign budgets. You track live performance against set goals and optimise accordingly. 

Neither are available in the UK yet but I’m sure we’ll get our turn to play soon.

Meta’s measurement reset

Meta has changed how it counts conversions:

“Click-through” now only includes actual clicks to your site

“Engaged-through” includes likes, shares, saves, video views.

They’ve also reduced the video view threshold from 10 seconds to 5 seconds, meaning more views now qualify as conversions.

Take note. Your click-through numbers will likely drop. Not because performance is worse, but because Meta has stopped counting things like likes as clicks.

The upside is that reporting is now more aligned with Google, so you should see fewer discrepancies across platforms. You will, however, need to reset your benchmarks.

Advertising Updates from March 2026

More control over AI generated ad copy

Google is giving advertisers more control over ad copy with expanded text guidelines in AI max campaigns. This allows advertisers to create guidelines for generative AI to follow when creating ad copy to help the ads to stay on brand. This should mean less time fixing messaging errors going forward.

Tik Tok Ads update

TikTok merged manual and Smart+ ad creation. You can now choose full automation, partial automation, or fully manual, across budget, targeting and creative.

Location fees for meta ads

Meta is passing “Digital Service Taxes” onto advertisers in the form of location-based fees. These are based on where your audience sees the ad (not where you’re based).

UK: 2%

France, Italy, Spain: 3%

Austria, Turkey: 5%

These come into effect from July 2026. So worth factoring into budget forecasts now rather than getting a nasty surprise later.

Social Media Updates from March 2026

Thumbnail editing on Instagram

You can now adjust the crop, zoom, and positioning of any post’s thumbnail in your profile grid without altering the original media. Great news for anyone who likes the grid to look perfect.

Instagram carousel posts

You can now reorder your carousel posts after they’ve been published.

Tik Tok completion rates

Tik Tok is increasing how much of your video people need to watch before it gets pushed to more viewers. Video completion rates matter more to the algorithm than they used to and re-watches carry more weight than unique views.

LinkedIn algorithm update

LinkedIn’s algorithm now understands the meaning of posts, not just keywords.

View From The Den March 2026

Oof. That was a long one. Sometimes all this change feels overwhelming. 

Yet, the more I read about change, the more I notice that the fundamentals aren’t really changing at all. This month:

Original, genuinely useful content matters more than ever;
And understanding your audiences is a real competitive edge.

Obviously, we already knew that. The only real change is that the platforms are doing more for us. So we need to learn how to feed them.

That’s it for your digital marketing update March 2026. If you missed last month’s roundup of what happened in Digital Marketing in February, you can check it out here.
