Trending content discovery frequently asked questions

Questions about how trend research and hashtag discovery work in PostNext.

What does the trending content discovery tool do?

It searches recent high-engagement posts across X, Instagram, LinkedIn, TikTok and YouTube for any topic you enter. This is a research tool for content ideation, not a virality predictor.

Which social platforms does it cover?

X (Twitter), Instagram, LinkedIn, TikTok, and YouTube. Threads is not covered yet.

Can I research hashtags around a topic?

Yes. Every trending post lists the hashtags it used, and you can pull a combined hashtag shortlist for any search. Useful for prepping campaigns and finding niche tags.

Can I filter by time window?

You can switch between 7, 14 and 30 day windows. Use 7 days for fresh trends, 14 days for ideas with staying power, and 30 days for evergreen topics or seasonal planning.

What metrics do I see on each post?

An estimated engagement level based on the public search snippet, plus the source link. Exact like and share counts are not pulled, so open the post for precise numbers.

How do I turn the research into actual posts?

Open a result and adapt it in the composer with AI, in your tone and for your channels. Inspiration boards are not available today, so draft what you like right away.

Does PostNext predict whether my posts will go viral?

No. There is no reliable virality predictor. The tool shows which recent posts in your niche earned strong engagement so you can write content informed by what is already working.

Is trend discovery on the Free plan?

Free accounts can run searches with limits on saved boards. Pro and Business raise those limits. A 7 day trial of paid tiers is available.
