Overview
Frequently asked questions
How does the Content Calendar licence work?
It is a one-time purchase for a downloadable tool — no subscription. You buy it once and the file is yours to keep and use.
Can I try the Content Calendar before buying?
Yes. Use the Try online button for a fully interactive demo with sample data already loaded — nothing to install and nothing is saved.
Can I import my data from a spreadsheet?
Yes. Use the Spreadsheet template button to save a CSV with the right headings, fill it in Excel or any spreadsheet, then Import spreadsheet to load it back. The file is read in your browser — nothing is uploaded.
Does my data stay private?
Yes. The tool is a single HTML file that runs entirely on your computer and makes no network requests, so nothing you enter is ever uploaded or shared.
Do I need Excel or any other software?
No. It replaces the spreadsheet template entirely: open the file in your browser (Chrome, Edge, Firefox or Safari) on Windows, Mac, Linux or a tablet, and start working.
How to use Content Calendar
The complete in-tool guidance, reproduced here so you can read it before you download.
What this tool does
CM8-381 plans what gets published and when. It tracks the cadence you are actually holding against the one you intended, finds the first week ahead with nothing in it, and shows which topics and buying stages you are covering — and which you have quietly stopped writing for.
Everything runs inside this single file — no account, no upload, no network request of any kind.
Which of the three calendars this is
Three tools plan time and they answer different questions:
- This one — what gets published, when, and whether the coverage has holes.
- An editorial production planner — how a piece moves from brief to published, and where the pipeline jams.
- A campaign calendar — which campaigns run when, and what clashes.
Use this one for the publishing plan and the production planner when the problem is that things are not getting finished.
Cadence beats volume
Cadence = pieces published in the last twelve weeks ÷ 12
Content compounds, and compounding needs consistency. A steady one piece a week for a year beats twenty pieces in January and nothing until May, because search engines, subscribers and the habit of reading you all respond to regularity rather than to bursts.
The monthly chart marks any month below 60% of target in red. What to look for is not the height of the bars but the gaps: a quiet quarter costs far more than a quiet week, and it takes months to recover the audience.
The first empty week tile is the one to check weekly. A content programme dies by running out of runway rather than by anybody deciding to stop it.
Writing for the wrong stage
Every piece is tagged with who it is for:
- Problem aware — they have the problem and not the vocabulary. Large audiences, slow conversion.
- Solution aware — comparing approaches. Smaller, warmer.
- Product aware — comparing suppliers. Small audience, and where almost all the conversion happens.
- Existing customers — retention and expansion, and usually the most neglected.
- Brand and news — necessary, and not a substitute for the others.
Most content programmes are almost entirely problem-aware, because those topics are the easiest to think of and produce the biggest traffic numbers. The pieces that actually convert are the comparisons, the case studies and the pricing explanations, and there are usually two of them.
Topic coverage
List the topics you are trying to own in Settings, and the coverage table shows a grid of topic against buying stage with a dash wherever nothing exists.
The pattern worth acting on is a topic with several problem-aware pieces and nothing further down. That topic attracts readers who then find nothing to move them along, and the traffic it earns converts at close to zero.
Depth in one topic beats one piece across ten. A topic covered at every stage builds something people can navigate; ten topics with one article each builds a blog.
The tool can only report absences you have named, so a topic missing from the Settings list cannot be reported as missing.
Lead time and pieces at risk
Record when each piece was actually commissioned — when somebody was asked to write it, not when it was first mentioned. The tool refuses to accept anything past the idea stage without that date, because it is what makes lead time measurable.
Anything still an idea inside the lead-time window is flagged. It will either be late or it will be rushed, and both are visible weeks in advance.
A piece with no promotion
A piece scheduled or in review with nothing in the promotion field is flagged, and it is the most common waste in content marketing: weeks of work, published, and then nothing.
The field only needs a line — "newsletter, LinkedIn, and the sales team's follow-ups". Its job is to make the absence visible, because a piece nobody promotes is read by whoever happens to find it.
Topical content does not keep
A piece past its publication date is flagged, and for evergreen content that is a nuisance. For anything topical — market commentary, a reaction, a seasonal piece — it is fatal: it goes out late or it goes out irrelevant.
The sample has one deliberately. If a piece is topical, either it gets priority or it gets dropped; what it should not do is sit in drafting for three weeks.
Updating beats publishing
Record a piece that updates an existing one in the update field. Refreshing a piece that already ranks, already has links and already gets read is routinely worth more than a new piece starting from nothing — and it takes a fraction of the time.
Almost every content calendar is entirely new pieces, because updates feel less like progress. They are usually the highest-return work available.
What this does not do
- It does not measure whether any of it worked. A full calendar is a plan.
- It says nothing about quality. Cadence can be held by publishing anything.
- It does not manage the production pipeline — statuses are recorded, not driven.
- It knows nothing about search demand. A topic nobody searches for can be covered perfectly.
- It cannot tell you when to stop covering a topic.
Printing and sharing
The Report tab prints the tiles, charts and both tables with a title block you fill in. The coverage table is the one for a planning session — it turns "what should we write next" into a grid with visible holes.
Saving your work
The calendar is held in this browser, on this computer, and stays there between visits. Use the backup button to write a JSON file you control.
Accuracy & disclaimer
Every entry here is one you made. The tool counts, groups and compares dates; it has no view on whether a piece is worth writing or whether anybody read the last one.
