Trending topics and hashtags that fit

What's starting to trend in your field's news, and which hashtags fit your post – within each network's hashtag rules.

Updated:

From your News radar sources (RSS, Google News for your topics), Sayweek counts which words and phrases come up clearly more often this week than last week – in your brand's language and country.

  1. Open the From news tab of the Ideas page and scroll to the Trending topics in your field card.
  2. For each topic you see how many headlines mentioned it this week and before, an example headline and a matching hashtag. + As an idea puts it into your Ideas box.
  3. In the post editor, click ✦ Hashtags that fit under the hashtag field: pick from trending and your own frequent hashtags that fit your text.

Rules per network

  • Suggestions never go over the network's limit: 3–5 hashtags on LinkedIn, 2–3 on Instagram, up to 2 on Facebook, X and Bluesky, 1 on Threads.
  • We don't suggest hashtags for Google Business Profile updates.
  • Of Google Trends' daily nationwide searches, we only show the ones related to your topics.
Where does the data come from?

Public sources only: your News radar RSS feeds, Google News searches and the daily Google Trends list. "Trending" here means news frequency, not paid search data.
