Short answer: Journal selection pricing depends on how deeply the manuscript and journal options are assessed. A useful service should consider research scope, article type, audience, journal aims and scope, indexing requirements, publication model, and author instructions rather than return a generic list.
Before ordering, ask how many journals will be shortlisted, what evidence will be provided for fit, and whether current indexing status will be checked through official sources.
For Web of Science coverage, Clarivate’s Master Journal List is the authoritative public source for current coverage. A third party can help interpret journal fit but cannot control or sell indexing status.
If your university or funder has specific requirements, provide them before the shortlist is prepared so the recommendations can be screened against those requirements.
