Audit says my Core Web Vitals need work. I've got room to improve on all of them but limited dev time this sprint. If I can only get my developer to fix one thing, which metric gives me the most bang? Mobile is where most of my traffic is.
On mobile, INP (Interaction to Next Paint) is usually the highest-leverage fix now that it's replaced FID — it's where most real sites are actually failing, and it directly reflects how sluggish your page feels when someone taps.
That said, look at which metric you're failing worst in the audit, because the answer is site-specific:
If CLS is red, do that first: it's often an afternoon of work for a full pass. If everything's borderline, spend the sprint on INP. Re-run the audit after to confirm the field data moves.
CLS was my worst and you nailed it — missing dimensions on our blog images. Dev fixed it in an hour and the score's already green. Doing INP next sprint.
