Questions

How do you grow on social media?

Post things people finish, answer, save or share, keep a steady rate, make each post for the place it appears, and answer the people who respond. Each platform rewards one of these most, so learn which before you start.

How often should you post on social media?

It depends on the platform: three to five feed posts a week on Instagram, two to five on TikTok and LinkedIn, once or twice a day on a Facebook Page, once a day or more on Threads, several a day on X, about one long video a week on YouTube and at least one Pin a week on Pinterest.

What is the best day to post on social media?

Wednesday on most platforms, with Tuesday and Thursday close behind. Sprout Social finds Tuesday and Wednesday strongest on almost every network. Long YouTube videos (Sunday) and Shorts (Friday) are the main exceptions.

What is the best image size for social media in 2026?

For video, 1080 × 1920 (9:16), which Instagram Reels, TikTok, Facebook Reels and Pinterest video recommend. For feed pictures, a 4:5 portrait: 1080 × 1350 on Instagram, 1440 × 1800 on Facebook. Pinterest prefers 2:3 at 1000 × 1500.

What should a social media content calendar include?

At least the date and time, the platform, the caption and the media for each post. Most people add the content pillar, the format and a status, so the calendar shows what is planned, what is made and what is still an idea.

What is the Add Yours sticker?

Add Yours is a prompt you put on a post that invites other people to answer it with a post of their own.
