This service fits store owners who want steady organic demand as part of their ecommerce marketing services. It works well when your products have real search demand, your catalog is stable enough to optimize, and you can publish changes on a regular basis.
It is not the best choice if you need sales next week. SEO compounds over time, and paid ads bring faster traffic. It also fits poorly when products change so often that pages never settle, or when you want a one-time fix with no follow-up. In those cases I will say so before any work begins, so you can choose between ads and a smaller audit first.
If your store also has a physical location, my local SEO services fit that case. If your store sells in English and Spanish, bilingual SEO keeps keyword research separate for each language instead of translating the copy.
