Quick answer
Mobile-first indexing means Google mainly looks at your mobile site when deciding how to rank you.
What it means
Mobile-first indexing means Google mainly looks at your mobile site when deciding how to rank you. In normal terms, it is one small part of how Google and people understand your site.
Why it matters
If your desktop site is lovely but your mobile site is broken, Google sees the broken version. Most customers probably do too.
What to do about it
Check key pages on a real phone. Make sure text is readable, buttons are tappable, menus work and important content is not hidden.
Bloom's take
Bloom treats mobile issues as real SEO issues, not just design polish.
