If you’ve been running LinkedIn ads lately and noticed your cost-per-click climbing while your lead quality feels a bit... shaky, you aren't alone. Honestly, the platform shifted under our feet this month. October 2025 has turned out to be the "Great AI Integration" month for LinkedIn, and it’s changing how we actually have to build campaigns if we want them to work.
Basically, the era of "set it and forget it" targeting is dead. LinkedIn is leaning so hard into automated creative and "Reserved" placements that if you're still using the 2023 playbook, you're essentially donating money to Microsoft.
Here’s what’s actually happening on the ground right now with LinkedIn ads news October 2025 and how you should be pivoting.
The "First Impression" Land Grab
LinkedIn recently rolled out something called Reserved Ads. This is huge. For years, we’ve fought for space in the feed, but now, LinkedIn is letting big spenders "buy" the very first ad slot a user sees when they open their app.
It’s expensive. Kinda like Super Bowl ad space for B2B.
But here’s the kicker: it’s not just for the giants. LinkedIn is pushing this "Prime Time" visibility because their research shows that 86% of B2B buyers start their journey with a "Day One List"—a mental shortlist of brands they already know. If you aren't in that top-of-feed slot during a major product launch, you might be invisible before the buyer even starts looking.
Why "Reserved" is polarizing
Some marketers hate it. They say it kills the "meritocracy" of the auction. Others, especially in enterprise tech, are jumping on it because it guarantees 100% reach within a 24-hour window. If you've got a webinar on Tuesday, you can basically own the feed on Monday.
The AI "Draft with AI" Reality Check
LinkedIn Ads in October 2025 are now almost inseparable from generative AI. The "Draft with AI" tool has moved out of beta for most regions, and it’s... surprisingly decent?
It uses your existing website content or a "seed" headline to generate multiple versions of intro text and images. You can even pull in Shutterstock visuals directly through the AI interface.
But here is the trap.
Because everyone is using these tools, the feed is starting to look like a "Sea of Sameness." We’re seeing a massive 25% misattribution rate—meaning people see an ad, like it, and then accidentally credit it to a competitor because the creative looks so generic.
Pro tip: Use the AI to generate the variations, but please, for the love of your ROI, swap in a human-shot video or a "brand character" that doesn't look like a stock photo.
The Death of the "See More" Link
One of the most tactical pieces of LinkedIn ads news October 2025 comes from the platform’s own reps: keep your intro text under 160 characters.
If your ad copy gets truncated by that little "See More" link, you’re losing money. Why? Because LinkedIn often charges you for that click to expand the text, but that click doesn't actually lead to your website or a lead form.
It’s a "wasted" engagement.
In a world where CPCs are hitting $15 or $20 in competitive niches like Cybersecurity or SaaS, you can’t afford to pay $18 just so someone can read your third paragraph. Get to the point. Fast.
Video is No Longer Optional (But It’s Different)
Short-form video on LinkedIn is growing at 12% year-on-year. But the "polished corporate video" is dying.
What’s working in October 2025?
- Native Video: Uploaded directly, not linked from YouTube.
- Dwell Time Gold: Videos that use captions and "how-to" frameworks.
- CTV Expansion: LinkedIn is now letting you run non-skippable video ads on Roku and Samsung TV using LinkedIn’s professional targeting data.
Imagine showing a B2B ad to a CMO while they’re watching the news on their living room TV. That’s the level of cross-device targeting we're seeing this month.
New Metrics: Saves and Sends
Finally, LinkedIn added two new metrics to Campaign Manager: Saves and Sends.
In the past, we obsessed over Likes and Comments. But LinkedIn’s 2025 algorithm values "depth of engagement." A "Save" is a massive signal to the algorithm that your content is high-value. If your ads are getting saved, LinkedIn rewards you with a lower effective cost because it deems your content "relevant" to the professional community.

Actionable Next Steps for Your Campaigns
Stop worrying about "virality" and start worrying about "intent." Here is how you actually win with LinkedIn ads this month:
- Audit your text length: Go into your active campaigns right now. If your intro text is over 160 characters, trim it. Make sure the value proposition is visible before the truncation.
- Test "Thought Leader" Ads with Events: LinkedIn now allows you to sponsor a member’s post that specifically mentions an event. This is the highest-converting ad format right now because it looks like a personal recommendation, not a corporate broadcast.
- Turn on Dynamic UTMs: LinkedIn finally streamlined this. Go to your account settings and enable account-level dynamic UTM parameters. It will save your tracking team hours of manual work and fix the "dark social" attribution holes in your CRM.
- Diversify from the "Blue and White": Since every B2B ad uses the same color palette, try using high-contrast colors (or even black and white) to break the "Sea of Sameness" in the feed.
The platform is getting smarter, but it’s also getting noisier. The winners this October aren't the ones with the biggest budgets—they're the ones who realize that AI is for efficiency, but human nuance is for conversion.
