How to Never Run Out of Content Ideas: Answer the Public, People Also Ask, Google Trends and AI

Most content calendars do not fail for lack of effort. They fail on a Tuesday morning when someone opens a blank document and tries to think of something to post. The fix is not more creativity. It is a short list of tools that show you what people are already asking, plus a routine that turns those questions into a mapped list of 20 ideas in about 30 minutes.

Key takeaways

• Four tools cover almost every ideation need: Answer the Public for questions, Google's People Also Ask box for subtopics, Google Trends for timing and region, and an AI assistant for volume and variety.
• The best ideas come from what your audience is already searching for, not from what you feel like saying that day.
• A 30-minute routine, run once a week or once a month, produces 20 usable ideas with each tool doing one job.
• An idea is not ready until it has a pillar, a format, a platform, a mix type and a status. Map it before you write it.

The four content idea tools and what each is best for

Each tool answers a different question, so use them in sequence rather than picking a favourite.

Tool	What it shows you	Best for
Answer the Public (answerthepublic.com)	The questions people ask about any keyword, hundreds at a time	Blog posts, FAQs, video topics, carousel content
Google People Also Ask	The related questions Google shows under a search; click one and more appear	Subtopics and angles; free and unlimited
Google Trends (trends.google.com)	How interest in a topic changes over time and by region, with side-by-side comparison	Spotting trends, seasonal planning, comparing topic popularity
AI tools (Claude, ChatGPT)	Lists of ideas on demand, in the categories you specify	Fast brainstorming, variations, getting past creative blocks

Answer the Public: hundreds of questions from one keyword

Answer the Public turns a single keyword into a list of the questions people actually type, grouped by words like how, why, what, can and which. Enter "teeth whitening" for a dental clinic in Beirut and you get the raw material for a month: how long it lasts, whether it hurts, what it costs, whether it works on veneers. Every one of those is a post. The tool is best for blog posts, FAQs, video topics and carousels, because those formats are built to answer a question directly.

Copy the questions into your ideas list as written. The way people phrase a question is the hook of your post.

People Also Ask: free, unlimited and already ranked

Google's People Also Ask box is the fastest way to find subtopics and angles, and it costs nothing. Search your topic, look for the box of related questions, and click one. A single search can produce twenty angles in a few minutes. Use it to break a big topic into pieces: "Meta ads" is too broad for one post; "how much should a small business spend on Meta ads" is a carousel.

Google Trends: when to publish and where

Google Trends tells you when a topic is worth publishing and which region cares about it. It shows how interest changes over time, lets you compare several topics side by side, and breaks interest down by country and city. That makes it the tool for spotting a topic on the rise, planning seasonal content (Ramadan, back to school, end-of-year sales) and deciding which of two topics deserves the slot.

A gym in Dubai comparing "home workout" against "gym membership" over twelve months can see when each peaks and plan its pushes around that rather than guessing.

AI: the prompt we teach for 20 ideas in one go

When you need volume or you are stuck, an AI assistant is the fastest way out. The prompt we teach in the PDMA is deliberately simple:

Give me 20 content ideas for [niche] targeting [audience] across educational, entertaining, and promotional categories.

Fill in the brackets with specifics. "Give me 20 content ideas for a skincare brand in Riyadh targeting women aged 25 to 40 across educational, entertaining, and promotional categories" produces far better results than a vague niche. The categories matter too: they force a spread instead of twenty variations of the same tip. If you want tighter output, add a role and a format, which is the RTF prompting framework we cover in the AI week.

AI is best for brainstorming quickly, generating variations and breaking a creative block. It is weakest at knowing what your audience is searching for right now, which is why it comes last in the routine.

A 30-minute ideation routine that produces 20 ideas

Run it once a month, or weekly if you post daily.

1. Minutes 0 to 5: pick the topic. Choose one content pillar for this session. If you have not defined pillars yet, start with content pillars first; every idea needs a home.
2. Minutes 5 to 12: Answer the Public. Enter the pillar keyword. Copy the eight to ten questions that match what you sell and what customers ask you in DMs.
3. Minutes 12 to 18: People Also Ask. Search the same keyword on Google, expand the box three or four times, and add five more angles you did not see in step 2.
4. Minutes 18 to 22: Google Trends. Check whether the topic is rising, flat or seasonal, and note which ideas should be scheduled for a specific month.
5. Minutes 22 to 27: AI. Run the 20-ideas prompt with your niche and audience, then keep only the five that are not already on your list. You now have around 20.
6. Minutes 27 to 30: cut and map. Delete anything you would not be proud to publish, then map what is left using the table below.

Map every idea before it becomes a post

In the PDMA we ask students to track six things for every idea: pillar, content idea, format, platform, mix type and status. That mapping is what turns the list from your 30-minute session into a content calendar.

Pillar	Content idea	Format	Platform	Mix type	Status
Marketing tips	5 free keyword tools	Carousel	Instagram	Educational	Draft
Success stories	Sarah's first client win	Reel	Instagram, TikTok	Inspirational	Idea
Program promo	New cohort open	Static post	All platforms	Promotional	Done

Mix type keeps you honest: if fifteen of twenty ideas are promotional, you have a sales sheet, not a content plan. Status moves in one direction, idea, draft, ready, scheduled, published, so anyone on the team can see what is stuck.

Keep the table in Notion if you want list, calendar and board views and several people editing, or in Google Sheets if you are a solo marketer or a small team already on Google Workspace.

Where this is taught

The ideation tools, the idea-mapping table and the tools for organising a content strategy are covered in week 5 of the Professional Digital Marketing Associate Diploma, where students build a mapped ideas list for their own brand before moving on to social media execution in week 6.

Frequently asked questions

Which content ideas tool should I start with if I only have ten minutes? Google's People Also Ask box. It is free, needs no account and gives you real search questions immediately. Search your topic, expand the box a few times and copy the questions that match your business.

Do I need a paid plan for Answer the Public? Start with whatever the free access allows and check the pricing page for current limits, since plans change. For most small businesses one search per pillar per month is enough, and Google's People Also Ask box fills the gap.

How many ideas do I actually need per month? Enough to cover your posting schedule with a small surplus. If you post four times a week, 20 ideas covers the month with a few spares for the days a plan falls through.
