Frequently asked questions

What does Social Media Post Time Optimizer do?

The conventional posting days for Instagram, Facebook, X, TikTok, LinkedIn, YouTube and six content niches, each with a cadence tip — flagged as a convention, not a measurement: replace it with what your own analytics say.

When would I actually use this?

Planning a post that fits: staying inside the character limit, exporting an image at the right size, and picking a slot when the audience is actually there.

What is the most common mistake?

Counting characters the way a text editor does. Emoji, accents and links are counted differently by each network — a link is often a fixed cost regardless of its real length.

How is Social Media Post Time Optimizer different from Social Media Character Counter?

They sit next to each other but answer different questions: Social Media Character Counter is the one to open when you need it to count characters against 15 social network limits — X/Twitter, Instagram, TikTok, LinkedIn, YouTube, Threads and more — with X's weighted rules (URLs = 23, CJK = 2) and a thread estimate. Pick whichever matches what you're starting from — both are free.

Is there a tool for the next step?

Social Media Image Size Guide is the closest one after this: Recommended image dimensions for Instagram, Facebook, X, YouTube, TikTok, LinkedIn and Pinterest, each flagged as documented by the platform or as a usage convention — plus a checker that tells you what your own image loses to the crop.

What else is worth having open alongside it?

Social post preview and Social image resizer — they come up in the same task often enough to be worth a second tab.

Where do the figures come from?

Limits and image sizes come from each network's published specifications, which change without notice and sometimes differ between the web and mobile apps. Check the platform before a launch that matters.

ExplainerWhen to Post, and Why the Answer Is Mostly Not the TimePublished best-time tables average over audiences that are not yours, and on a ranked feed posting time matters far less than it did on a chronological one. Compute your own audience's activity across time zones instead — six zones flatten the timing lever from a 94% swing to a 22% one — and see how many posts a real timing test needs.GuideSocial Image Sizes, and the One Crop That Survives EverywherePlatforms crop rather than letterbox, so an image is only safe if its subject sits inside the intersection of every ratio it will be shown at. That intersection has a closed form — the narrowest ratio divided by the widest — and it works out at 29.45% of the source for a realistic set. Geometry that does not expire, plus the pixel counts that do.ExplainerHashtags Are a Search Index, Not a MegaphoneA hashtag makes a post findable in a query, which is a different job from making it spread. Model the visibility a tag actually buys and the answer falls out: a tag's worth is its viewers-per-post-published, not its volume — so a very popular tag returns almost nothing and a specific one returns twenty-five times more.ExplainerWhat an Influencer Earnings Calculator Is Really EstimatingThese tools multiply followers by an assumed rate per thousand, which makes them a CPM model under another name — and every input behind that rate is an assumption they never show you.How-toResizing an Image for Each Network Without Distorting ItMeasured on the resizer itself: Fill is a centre crop with no focal point, and a portrait photo loses 38.9 percent off the top for an X-sized banner. Plus the current published dimensions, each with the date it was checked.ExplainerHow Much Does TikTok Pay Creators? Every Route, and Which One Is Actually the MoneyThere is no single per-view rate, and every page that quotes one is mixing four unrelated payment routes. Here is what each route actually pays, what moves you within the range, and why the fund is the smallest line for most accounts.
