How to Plan Quarterly Content Themes

Adam Mosseri, the Head of Instagram, named the rubric every quarterly content theme has to defend against in a January 8, 2025 Reel published to @mosseri (instagram.com): "Watch time, likes per reach, and sends per reach," per Mosseri, with sends per reach the load-bearing signal for distribution beyond an account's existing followers. Most quarterly content plans I have audited in 2026 are organised around topic buckets (product, education, founder, behind-the-scenes) with no signal target attached, which is structurally the same as planning a 13-week training block with no idea which energy system each session is supposed to develop. The themes ship, the calendar holds for six weeks, and the mid-quarter retrospective reads as a tour of view counts with no falsifiable decision attached.

The quarterly plan that compounds across the calendar year is the one whose four themes each target a different ranking signal, whose 13 weeks are sequenced so the signals build on each other, and whose mid-quarter audit produces concrete next-quarter decisions before week 9 ends. This page is the procedure for running that signal-mapped quarterly plan on Instagram, TikTok, and LinkedIn. It is the procedure I run on the small B2B product account I operate, and a structurally similar version is what I have watched senior in-house and agency operators run on consumer and creator-led brands in 2026.

What we're actually solving

The thing most quarterly-planning pages get wrong is treating the quarter as a list of campaigns stitched together by a colour palette. A quarter is a four-theme signal-distribution problem that produces a list of campaigns as a side effect. The unit of the plan is the theme, not the post; each theme has a named signal target, a named metric, and a named kill criterion.

Three things have hardened in the quarterly-planning conversation since 2023, and each one changes the working shape an operator can defend. The reach baseline has reset platform-wide: Buffer's 2026 State of Social Media Engagement report (buffer.com), built on 52 million posts across ten platforms, recorded a 24% year-over-year drop in median engagement rates, and Metricool's 2026 Social Media Study (metricool.com) recorded a 35% drop in Reels reach. A quarterly plan that uses 2024 assumptions will under-deliver by 25 to 35% on the same content quality.

The ranking signals are public, named, and ranked: Mosseri's January 8, 2025 framework is the rubric the four themes have to distribute across. A quarter built entirely on the watch-time signal produces a quarter of saves and dwell but no compounding follower growth, because the unconnected-reach distribution depends on the sends signal. Cadence is bounded on both sides: the Sprout Social Index 2025, the largest published cross-brand survey of more than 2,000 marketers, recorded that consistency at 3-to-5 publishes per week is the single most cited correlate of follower growth, and a 35-percentage-point gap between teams that report results (76%) and teams whose reports drive next-month decisions (41%).

What a quarterly content plan is not. It is not 13 weeks of weekly themes loosely strung together. It is not two big launch weeks and 11 weeks of filler. It is not one theme per month with no signal target. The procedure below produces a four-theme signal arc, a 13-week sequence that builds toward unconnected-reach distribution, and a mid-quarter audit that names three concrete decisions before the quarter ends.

Step by step

1. 01

   Step 1. Pre-commit the two numbers before naming any themes (45 minutes)

   Sit with the founder, CEO, or CMO and ask the Karten question: what are the two numbers that will tell us, on the day the quarter ends, whether it was worth the spend? Rachel Karten, who writes Link in Bio to roughly 100,000 in-house social media managers, named the discipline in her March 11, 2024 measurement piece (milkkarten.net): "Pick the two or three numbers that change what you'd do tomorrow," per Karten. Common answers across brands I have audited are follower-conversion-rate on profile visits from non-followers, revenue attributed to social via UTM (DTC), demo bookings (B2B), and waitlist sign-ups (pre-launch). Pick the headline business number and the leading-indicator number, ideally sends-per-reach on the brand-equity theme. Commit to both in writing before any theme is named.

   Deliverable

   A one-paragraph commitment block with the two numbers named and the Q-end target attached to each.

2. 02

   Step 2. Assign one Mosseri signal target to each of the four themes (60 minutes)

   Theme A is the sends-driver (brand-equity commentary, named-number contrarian opinions). Theme B is the watch-time-driver (long-form tutorials, deep dives). Theme C is the likes-per-reach driver (aesthetic content, founder-routine). Theme D is the intent-to-action driver (testimonials, customer reactions, demo invitations). Each theme gets a one-sentence definition, a brand-twist pulled from the Tucker rule, and a signal target with a numeric floor (the prior-90-day median plus 25 to 50 percent). The companion procedure for the calendar that follows is the content-calendar-that-works page.

   Deliverable

   A 4-row theme table with signal target, one-sentence definition, and numeric floor per theme.

3. 03

   Step 3. Sequence the four themes across the 13 weeks using the build-up rule (45 minutes)

   The sends-driving theme runs all 13 weeks at one post per week (the brand-equity anchor that is always present). The watch-time theme runs weeks 1 to 6 as the foundation-building period. The likes-per-reach theme runs weeks 4 to 10 as the mid-quarter aesthetic anchor. The intent-to-action theme runs weeks 7 to 13 as the conversion arc. The build-up rule is why the quarter compounds: sends-driving content runs the full length, watch-time runs the first half, intent-to-action runs the second half, and the likes-per-reach theme bridges.

   Deliverable

   A 13-week sequencing chart with each theme plotted across the weeks it is active and the per-week post count.

4. 04

   Step 4. Apply the Tucker brand-twist rule to every theme (30 minutes)

   Kendall Hope Tucker runs social at Ramp, whose Brian's Office series Marketing Brew called, in its October 22, 2025 coverage (marketingbrew.com), "an unlikely viral marketing series," per Marketing Brew. Tucker told the reporter the working rule for the series: "We try to lean into the trend, but always with a Ramp twist," per Tucker. For each of the four themes, write the brand-twist as a one-sentence rule that names what your brand can run that competitors cannot. Theme A's twist is usually the founder's specific credential. Theme B's twist is usually the product's specific math or proprietary process. Theme C's twist is the brand's aesthetic codes. Theme D's twist is the customer cohort the brand has built relationships with. Without the brand-twist, each theme is a category-generic bucket; with it, the theme is defensible.

   Deliverable

   A four-line brand-twist statement, one per theme, that competitors cannot replicate.

5. 05

   Step 5. Run the mid-quarter audit at week 6 to 7 (90 minutes, calendared in week 1)

   The mid-quarter audit is the calendared block that closes the Sprout reporting-decision gap. Pull the per-theme metric data and answer three questions in writing. One: is the sends-driving theme tracking against the leading-indicator target? Two: is the watch-time theme producing the audience-priming dwell time the intent-to-action theme will need in weeks 7 to 13? Three: what is the one specific decision (expand, trim, or sharpen the brand-twist) that the next six weeks will execute?

   Deliverable

   A one-page audit memo with the three answers and the one decision named explicitly.

6. 06

   Step 6. Run the quarter-end retrospective in the Karten two-numbers shape (90 minutes in week 13)

   The retrospective is a one-page memo: the headline business number from Step 1 (absolute and vs. target) and the leading-indicator number (same shape). Below: the theme-level breakdown of which theme drove which share of the headline. Below that: three specific decisions for the next quarter. The retrospective fits on one page; if it does not, the appendix has crept into the headline.

   Deliverable

   A one-page retrospective memo with two numbers, theme breakdown, and three next-quarter decisions.

What good looks like

Five named benchmarks anchor what a healthy quarterly content plan should produce. The first is Theme A sends-per-reach clearing 0.65%. The benchmark I see consistently across friends-of-the-house brand commentary clusters in 2026 is roughly 0.6 to 1.2 percent sends-per-reach on the brand-equity theme. Clearing 0.65% predicts the follower-conversion lift in the second half of the quarter.

The second is cadence holding at 4 posts per week across 12 of 13 weeks. The Hoyos production-block discipline keeps the cadence inside the band; the one-week dip allowance is for the next planning block. The third is follower-conversion-rate on non-follower profile visits lifting 40 to 80 percent (from a 0.4% baseline to 0.55 to 0.72%), concentrated in weeks 8 to 13.

The fourth is the mid-quarter audit producing exactly one specific decision, not zero, not three. Alex Hormozi has named the rule that holds at the same shape across most operating disciplines: "Boring done consistently beats brilliance done once," per Hormozi. The mid-quarter audit turns one consistent decision into eight weeks of compounding execution. The fifth is the week-13 retrospective fitting on one page: two numbers on top, theme breakdown in a table, three decisions at the bottom.

Common mistakes

I have planned a quarter with four themes that were structurally the same signal target. The first time I ran a quarterly plan on the small B2B product account I operate, all four themes were watch-time-and-saves drivers. The dwell time was excellent. The follower growth was flat. The lesson is that all four themes are great content is a sign the signal architecture has collapsed into a topic-bucket plan.

I have skipped the mid-quarter audit because the data looked noisy. Week 6 of a Q1 plan, sends-per-reach was tracking at 0.31% and I waited four more weeks before deciding. By week 10 the brand-twist that needed sharpening had never been sharpened. The fix is the calendared 90-minute block on the Monday of week 7.

I have written quarterly plans that drifted because the brand-twist was implicit. The executing operator drifted into category-generic versions of Theme A because the brand-twist was in my head, not in the plan document. A brand-twist that does not live in writing is a brand-twist that does not survive a busy week.

The other failure modes I see across plans I have audited: themes ship as topic buckets rather than signal targets (every theme exercises watch time and saves; none exercises sends per reach); cadence surges and collapses (4 posts per week becomes 7, then drops to 1 to 2, and reach takes 30 to 60 days to recover); the retrospective never gets written (the quarter ends, the team is already planning the next quarter, the three specific decisions the retrospective should have produced never get written).

Metrics to track

Theme A sends per reach. The leading indicator. Floor is the prior-90-day baseline; Q-end target is at least 25 to 50 percent above baseline.

Follower-conversion-rate on non-follower profile visits. The structural outcome. Tracked weekly across the 13-week quarter.

Cadence consistency. Weeks inside the Sprout 3-to-5 band. Target is at least 12 of 13.

Business outcome. Revenue attributed to social via UTM (DTC), demo bookings (B2B), or sign-ups (pre-launch).

Mid-quarter audit completion. Binary: did the calendared 90-minute block happen and produce one specific decision? Skipping this audit is the single largest predictor of a quarter that ships clean and converts nothing.

Where a planning-first tool fits

The procedure runs in a planning document, a tracking spreadsheet, and the platform-native analytics. None of those steps require a third-party tool. The places a tool earns its slot are bookkeeping-heavy: surfacing candidate themes from your brand profile, scoring proposed hooks against the sends-driver patterns, and routing the mid-quarter audit and week-13 retrospective into a one-page format. A planning-first tool that takes the brand profile and prior-quarter data as inputs and outputs candidate post briefs per theme is one option among several, alongside a Notion document plus a Google Sheet. The methodology is what matters; the tooling is the speed dial on the methodology. Superdirector is the planning-first tool I built around this procedure.

Disclosure by Bell Chen, founder of Superdirector: the brand-profile and planning features mentioned in this piece are part of the product I build. The procedure on this page is what I run on the small B2B product account I operate, and a structurally similar version is what I have watched senior in-house and creator-led brand operators run on retainer brands in 2026. The Vespera Skin worked example referenced in the source draft is a fictional composite, calibrated against the 2026 cross-brand benchmarks from Metricool, Buffer, and Sprout Social cited in the body.
