For a low-medium COL area you’re going to need to offer 85k-95k base minimum to attract someone with the experience necessary to fully audit, create a strategy, and execute that strategy.
For a higher COL area, more. Possibly less for a full remote position, but a solid SEO probably won’t take a haircut for the privilege of full time WFH anymore.
If your current agency or external vendor is asking *you* what needs to be done, fire them. No SEO agency worth anything is going to be asking the client about tasks, they’re going to be telling you what they’ve identified needs to be done and getting your sign off on the strategy and content required.
If you don’t want to commit to in-house yet (it’s tough without background, there’s a lot of BSers), tap your network for recommendations. Guarantee you know someone who has worked with a real SEO pro or agency.
Stay away from large media companies, they’re turn and burn shops.
