Google Discover Headline Generator: Common Mistakes and Best Practices

Most problems with google Discover Headline Generator aren't caused by not knowing what to do — they're caused by small, easy-to-miss mistakes that compound quietly over time. Here are the ones that come up most often.

Mistake 1: Writing search-engine-style keyword-front-loaded headlines that read awkwardly as a feed hook, even if they'd work fine as an SEO title.

Mistake 2: Using low-quality or stock-looking images that don't stand out in a visually dense feed of competing content.

Mistake 3: Publishing evergreen content and expecting Discover behavior identical to search — Discover rewards recency and topical relevance more heavily.

The fix for most of these isn't more effort, it's a regular check. A few habits that prevent them from creeping back in:
- Publish content tied to timely, currently-relevant topics when possible — Discover favors freshness more heavily than classic organic search does.
- Keep headlines specific and concrete rather than vague — 'Why X happened' undersells if you can say exactly what X is in the headline itself.
