And it is not the kind of software a weekend replaces. - You could make: Schema markup: an app builder makes this well. - You could not: A crawler that checks every page of a site. - You could not: A score built from what the top results for each keyword cover. - You could not: Speed tests run from real browsers on a schedule. - You could not: AI features, unless you pay a model provider for each request yourself. A judgement by ToolGPA from this listing, by rules that are the same for every tool.
