Quick verdict
- → Optmyzr goes deeper on Google mechanics than GoMarble does, and for a search-only account that depth is the right buy.
- → GoMarble covers Google alongside Meta, TikTok and LinkedIn, and leads with diagnosis rather than an optimization checklist.
- → The deciding question is usually channel mix, not feature count: search-only favours Optmyzr, cross-channel favours GoMarble.
Optmyzr vs GoMarble, in three lines
If you don't want to read the whole comparison, this is the shape of the gap.
Coverage
Optmyzr is search and shopping led across Google, Microsoft and Amazon. GoMarble covers Google alongside Meta, TikTok, LinkedIn and Bing, so a cross-channel account is diagnosed in one place rather than split across two tools.
Depth vs breadth
On Google mechanics specifically — bidding scripts, shopping structures, rule engines — Optmyzr goes deeper than GoMarble does. The trade is that its depth stops at search while a growing share of most accounts does not.
The one thing Optmyzr does that GoMarble doesn't
Its rule engine and script library give Google specialists a level of hands-on control that GoMarble deliberately abstracts away. If you want to build and tune your own optimization rules at that granularity, that is Optmyzr's lane.

Final verdict: For teams searching for an Optmyzr alternative in 2026, the honest split is channel mix. If search and shopping are the bulk of your spend and you have the specialism to use it, Optmyzr's Google depth is genuinely hard to beat and we would not pretend otherwise. If your spend is split across Google and Meta, GoMarble diagnoses both together, explains why metrics moved rather than listing what to improve, and executes the fix once you approve it.
