I regret my website redesign

Wow, you are very lucky if you've never had really bad fries. I've been to places and had undercooked fries, burnt fries, fries with almost no potato in them, soggy fries. McDonald's fries are very okay but they are always okay. They are very rarely hot though, usually quite old, but at least not stone cold like KFC fries (in the UK and Europe we have fries instead of mash with fried chicken). The fries in Belgium are by far the best, but there are some great ones here in Germany.

I don't know where you got the idea that this agency has any experience in design conversions or building funnels, but I won't dismiss your comment entirely.

From a design standpoint, my biggest gripe is with the first two sections on the landing page design. I mean, it quite literally looks like either the site is reselling (drop-shipping) or it's a knockoff scam. At no point did I get the impression of "brand identity" or "this product looks trustworthy".

Which means that the primarily source of sales for this product is word of mouth (reputation), and to be fair I wouldn't be surprised if this agency just realized that themselves and exploited the whole idea.

If reputation is how you get sales, then why give a shit about building a brandable design. A design that actually converts and is possible to measure in long-term.

what i like to do is work with agencies for a limited trial period. i give them a couple of easy, medium, and hard tasks, and see how they fare. based on their performance, i hire them or move on to someone else.

This helps me test the hypothesis that this is the right group for the job.

That said, I don't know if that would have helped OP. It seemed like timing (End of year is always a slowdown due to holidays, and Feb-April are when other clients start ramping back up) was not on their side, but breaking things down into more bitesized work could have helped. Most of the work I saw was mockup/design work, which is more creative/subjective than your typical "Make button do X" kind of task.

I don't want to rub salt in the wounds here, but that design is extremely mediocre. The primary mistake here imo was to think you needed professional web design in the first place. You didn't.

Professional web design is best suited to companies with a strong brand or websites with complicated UX/UI that needs wireframing. You're just a small business selling KVMs D2C. That doesn't need anything fancy.

There are some really good (free) AI logo generators out there you can use to generate logos very similar (perhaps even better) than this. In recent years I've used them almost exclusively to generate some initial logo ideas then either made minor alterations myself (where needed), or paid someone a little to do it for me.

Similar things can be said for web templates. There are some really good customisable templates for simple sites like yours out there today. I don't know why you'd pay someone for something so simple, especially when the design is so generic and forgettable (no offense).

I don't mean to be so critical. The design isn't bad. The site looks clean and it's pleasant to use. It's just insane to me that your main takeaway here was that you should have hired a freelancer instead of an agency.
