How the guides and tools are made

Who writes them

PostLink is run by Dawid, an independent developer who builds small web tools for creators. He writes and maintains the guides and the tools on this site. There is no content agency, no guest posts and no paid placements.

Where the facts come from

A guide starts from the question people actually search for — what a label means, whether the other person is notified, which numbers a program requires. The answer is taken from the platform’s own documentation first: the Instagram, Facebook and TikTok Help Centers, YouTube Help and the Creator Academy, and the published program terms.

Where the documentation is silent — what a screen looks like today, which menu an option moved to — the steps are checked in the app. Where neither gives a firm answer, the guide says so instead of guessing. Guides that rely on official pages list them under Sources at the end.

How AI is used

Some drafts are written with the help of AI writing tools. Nothing is published on that basis alone: the requirements, numbers and steps in a guide are checked against the sources above before it goes live, and again when it is updated.

Several free tools use AI on purpose — the title, description and chapter generators, the video summarizer, the profile picture maker. Their output is a starting point: read it before you publish it, the same way you would a draft from anyone else.

Keeping guides current

Instagram, TikTok, YouTube and Facebook change their apps every few weeks. Each guide shows the date it was first published and the date of its last real update; the update date only changes when the content does.

Guides that stop being useful are retired rather than left to rot. In October 2026, for example, the scheduling guides, “best time to post” tables and tool comparisons were removed once PostLink stopped offering a scheduler, so that every guide left on the site answers a question about the platforms themselves.

How the free tools get their data

The YouTube tools read public data through the official YouTube Data API: comments, tags, playlist lengths, subscriber counts and region restrictions are what YouTube reports for that video or channel at the moment you run the tool. Transcripts come from the video’s captions.

Calculators — the YouTube and TikTok money calculators and the engagement rate calculator — show estimates, not payouts. Their pages explain how the number is worked out, and none of them is official platform data.

Ads and independence

The guides and free tools are paid for by Google AdSense ads shown next to them. Advertisers do not choose, review or pay for any guide, and there are no affiliate links. When a guide mentions a PostLink tool, it is because the tool does the job described.
