Instagram growth strategy: Why a simple cross-post beat Threads

There's a specific kind of creator pain: you grind for months on the "new" platform... then one lazy cross-post on the "old" platform outperforms everything.

Annoying. Also useful. Because it tells you where the algorithm is actually willing to introduce you to strangers right now - not where you wish it would.

What happened

A creator named Tami Oladipo has been running a public growth experiment across platforms. She already built a serious audience on LinkedIn (20,000 followers), then tried to repeat the trick on Threads - aiming to go from 366 followers to 1,000 by December 15, 2025. She landed at 824 and didn't finish the sprint.

Then she cross-posted a simple short video she originally made for LinkedIn (about finding remote jobs) onto Instagram. That's the one that popped: around 110,000 views in a month, and her Instagram account moved from roughly the low-1,000s to 2,319 followers within a few weeks.

So she's shifting focus. Not deleting Threads. Just being honest about where momentum showed up.

That timing isn't random. Instagram has been leaning harder into "recommendations" (content shown to people who don't follow you) and getting stricter about what it considers original. In early May 2026, Instagram's Adam Mosseri said the platform is expanding its "unoriginal content" enforcement beyond Reels - so accounts that mostly repost other people's photos/carousels can lose recommendation reach (i.e., shown mostly to followers). Instagram also said a large chunk of US recommendations now come from original posts.

And Instagram quietly gave creators a new toy for low-risk testing: "Trial Reels," where you can publish a Reel as a trial first and see how it performs before showing it broadly on your profile. The feature started as tests and then rolled out more widely.

Why creators should care

Attention: Instagram's discovery engine is still one of the biggest in the game - and it's currently rewarding original work harder than it rewards clever reposting. If you make your own stuff, that's a tailwind. If you've been "curating," that's a headwind.

Distribution: The Reels vs. carousels argument isn't vibes anymore. Large-scale platform data shows Reels tend to win on reach (more new eyeballs), while carousels tend to win on engagement (more saves/comments). That means format choice is a lever, not a personality test. ([buffer.com](https://buffer.com/resources/instagram-reach-engagement-analysis?utm_source=openai))

Workflow: The sneaky lesson from this whole pivot: "platform fluency" matters. Tami wasn't starting from zero on Instagram - she'd been using it for years, so she already had taste for what looks native there. Threads, on the other hand, pushed her into a faster, more reactive writing style she hadn't built muscle for yet.

Monetization: Even if you're not doing brand deals today, the platform you grow on shapes the offers you get tomorrow. Instagram remains a default "portfolio" for many brands and agencies, while Threads is still more of a conversation layer. Threads is also still growing at massive scale - Meta said it crossed 400M monthly active users in August 2025, and Similarweb data cited in January 2026 put Threads ahead of X in daily mobile users.

What to do next

• Run a 14-day cross-post test like a grown-up. Take 5-7 proven posts (stuff that already worked somewhere) and publish them on Instagram with minimal tweaks. Don't "start fresh." Your job is to find which of your existing ideas survives the move.

• Pick formats based on the outcome you want. Need new people? Reels. Need depth and saves? Carousels. Want both? Mix them intentionally, not randomly. The data backs this split pretty consistently. ([buffer.com](https://buffer.com/resources/instagram-reach-engagement-analysis?utm_source=openai))

• Use Trial Reels to test hooks, not your identity. Make two versions of the same core idea (different first line, first frame, or pacing). Trial it. Keep the winner. Instagram built this feature for experimentation - use it like a lab, not a confessional. ([macrumors.com](https://www.macrumors.com/2024/12/10/instagram-trial-reels/?utm_source=openai))

• Audit your "originality" risk before Instagram audits you. If your feed is mostly reposts-with-a-caption, expect recommendation reach to get weird. The platform's moving toward rewarding original creators and limiting exposure for accounts it labels "unoriginal," now across photos/carousels too.
