The 'see more' fold is your real headline

The question: how much does the visible portion above the 'see more' cutoff determine whether a post gets read at all?

An analysis correlated the first-line content of posts with expand-rate (the share of viewers who tapped 'see more') and downstream dwell time. Method: text-feature analysis against engagement — descriptive, correlational.

Three findings:
— Posts whose first two lines posed a specific tension or number had markedly higher expand-rates than posts that opened with context-setting.
— Front-loading the conclusion did not kill curiosity; specificity did the work, not withholding.
— Expand-rate predicted dwell time, which (per other work) predicts reach — a chain of cheap-to-measure signals.

Caveats: first-line effects entangle with topic and author; correlational — treat as directional.

What it means for B2B: the ~140 characters above the fold are doing the job of a headline. 'Here are three lessons from our Q3 campaign' wastes it; 'Our best-performing campaign had the worst click-through rate — here's why' earns the expand.

Bottom line: write the visible lines like a headline, because functionally that is what they are.
Last-touch attribution is overcrediting your bottom-funnel

The question: when last-touch attribution gives a branded search or demo form the credit, what earlier touches are being erased?

A modeling exercise compared last-touch attribution (all credit to the final interaction) against a multi-touch model on the same B2B deals. Method: re-running both models over identical conversion paths — isolating the methodology effect.

Three findings:
— Last-touch concentrated credit on branded search and direct visits — channels that capture demand others created.
— Top-of-funnel social and content, which rarely sat in the final touch, were systematically undervalued.
— Deals with more touchpoints closed at higher rates, suggesting breadth of exposure matters even when no single touch gets credit.

Caveats: multi-touch models embed their own assumptions; both are estimates, not truth — treat as directional.

What it means for B2B: if you cut the channels last-touch ignores, you may quietly starve the demand that feeds your 'high-performing' branded search. The model that looks efficient can be hiding the engine.

Bottom line: the channel that gets the credit is often not the channel that did the work.
Employee posts out-reach the company page — but the math has a catch

The question: do employee-shared posts genuinely extend brand reach, or do they mostly recirculate to the same overlapping networks?

A reach study compared identical content posted from a company page versus from employees' personal profiles, measuring unique reach and network overlap. Method: same content, different distributors, deduplicated audience — the overlap measure is the important part.

Three findings:
— Personal profiles out-reached the company page per post, consistent with the platform favoring people over brands.
— But employees' networks overlapped heavily with each other, so aggregate unique reach grew far less than the sum of individual reach implied.
— Reach added by an employee depended on network diversity, not follower count — a connected outsider added more than a high-follower insider.

Caveats: overlap is hard to measure precisely; samples skew to willing sharers — treat as directional.

What it means for B2B: 'we have 500 employees, that's 500x reach' is the overlap fallacy. Real incremental reach comes from employees whose networks differ from each other's, not from sheer headcount.

Bottom line: advocacy scales with network diversity, not employee count.
Pairs well with this channel

The 'best time to post' is mostly noise once you control for audience

The question: do universal best-posting-time charts hold up, or do they vanish once you account for who your specific audience is?

A timing study tested generic optimal-time recommendations against account-specific audience-activity data. Method: compared reach from 'recommended' slots versus each account's own peak-activity windows.

Three findings:
— Generic best-time charts explained very little variance once audience timezone mix and seniority were controlled.
— The early-engagement 'golden hour' mattered, but its clock time depended entirely on when each account's audience was active.
— Consistency of posting time mattered more than the specific hour — a predictable cadence let the audience learn when to look.

Caveats: activity data is platform-dependent and lagged; observational — treat as directional.

What it means for B2B: 'post at 9am Tuesday' is a population average that may not describe your population. Read your own audience-activity data; for a global B2B audience the single best time may not exist.

Bottom line: ignore universal time charts. Find when your buyers are awake, and show up then, consistently.

Алиса AI будет конкурировать с Google AI Studio

Яндекс разворачивает экосистему AI-агентов на базе Алисы с доступом сначала для компаний, затем для всех. Агенты уже работают в Яндекс Такси и Лавке, скоро появятся в браузере и студии разработки. Платформа интегрирует стандартные функции — заказ такси, покупки, анализ данных. Алиса AI показывает неплохие результаты: менее известна, чем конкуренты, поэтому предлагает щедрые лимиты на видеогенерацию и работу с контентом. Яндекс планирует внедрить…

В Zennoposter добавили ИИ-помощник

Zennolab добавил в Zennoposter встроенный ИИ-кубик с доступом к четырём моделям (Gemini, DeepSeek, Claude, ChatGPT) — 50 бесплатных запросов в сутки. Есть режимы Assistant (чтение) и Agent (автоматическое создание скриптов), плюс новый GET-запрос по API. Нейросети хорошо справляются с регистрацией, постингом, фармингом аккаунтов и простым кодированием, но требуют проверки при парсинге динамических сайтов и диагностике ошибок. В связке с Zennoobr…

Новую Google reCapcha прошли статичной картинкой

Google выпустил обновленную reCAPTCHA, требующую движений рук для прохождения, но система оказалась уязвима к обходу. Достаточно транслировать статичное изображение с нужным жестом через виртуальную камеру с помощью простого Python-скрипта, чтобы нейросеть пропустила пользователя. Это создает серьёзный риск для сайтов: защита от ботов, позиционировавшаяся как прорыв, на деле не работает. Баг остается актуальным и позволяет спамерам легко автомат…

The U-shaped curve of B2B post length

The question: are short posts better because attention is scarce, or do longer posts earn more dwell time and reach?

A length study binned posts by character count and plotted engagement-rate and dwell time against length. Method: binned medians across thousands of posts — descriptive, vulnerable to topic confounds.

Three findings:
— The relationship was U-shaped, not linear: very short posts and substantial long-form posts both outperformed the mushy middle.
— Mid-length posts (a few sentences of unremarkable observation) performed worst — too long to be punchy, too short to be substantive.
— Long posts won on dwell time; short posts won on share-rate. Different lengths optimized different signals.

Caveats: length correlates with topic and effort; cannot isolate length alone — treat as directional.

What it means for B2B: pick a side. Either a tight, quotable observation built to be shared, or a genuinely deep piece built to hold attention. The forgettable middle is where reach goes to die.

Bottom line: be short and sharp or long and deep. Avoid the medium-effort middle.

DeepSeek представит последнюю версию v4

DeepSeek выпустит v4 в середине июля с новой моделью ценообразования API: токены подорожают в 2 раза в часы пиковой нагрузки (09:00–12:00 и 14:00–18:00 по пекинскому времени). Компания планирует уведомлять пользователей по почте за 24 часа до изменения тарифов. Проблема с ошибками «server busy» останется, но обойдётся дороже — это может существенно повлиять на экономику проектов, которые активно используют API DeepSeek для автоматизации и масшта…

Anthropic выпустили Sonnet 5

30 июня вышла Claude Sonnet 5 — новая версия позиционируется как самая агентная в линейке и приближается к флагманской Opus 4.8. Модель лучше справляется со сложными многоуровневыми задачами, устойчива к вредоносным запросам и не генерирует эксплойты. Sonnet 5 доступна на Free-тарифе, но тестирование показало скромные улучшения: хотя работает лучше Sonnet 4.6, её обгоняют конкуренты, включая китайские модели, которые дешевле через API при лучшей…
