If you have money at a major brokerage, check their HYSA and/or money market rate offerings, which may not be listed in the likes of NerdWallet. Personally, I find that the convenience of having it connected outweighs the fraction of a percent difference between theirs and the very highest rate out there. They also seem to be more likely to raise rates when the prime rate increases. One of my other institutions makes up new accounts (branding, not features) to promote when rates rise, rather than raising rates for existing accounts.
Also, one of the most difficult accounts to sort out after a loved one passed was a HYSA he'd chosen for its once-great rates. The institution was kind of a no-name then and has only become more obscure with time. The more separate institutions involved, the more steps for your executor and heirs.
Go ahead and chase rates or bonuses if you're getting enough value to be worth your time, but at least be organized enough not to forget old accounts or lose passwords. Keep beneficiaries or transfer-on-death instructions up to date. Try to "declutter" as you go, so you don't leave a trail of leftover or abandoned accounts if tomorrow's best rates are somewhere else.
