Shepherd connects to your Amazon Advertising and Selling Partner accounts and manages bids, budgets, and keywords automatically — every action statistically grounded, gated for safety, and explained back to you.
Shepherd reads performance data from Amazon over authorized, encrypted connections, processes it through its decision engine, and writes optimization actions back through the official Amazon Advertising API. Nothing leaves this loop.
No black-box guessing. Shepherd runs each decision through a fixed, auditable pipeline — and refuses to act until it has the statistical confidence to back the change.
Shepherd pulls the latest campaign, keyword, and target metrics from your Amazon accounts over authorized, encrypted API connections.
Shepherd estimates each keyword's response curve from its own conversion data, climbs to the most profitable bid, then ramps exposure in controlled steps — re-checking efficiency before every increase.
Each keyword's curve is learned from its own conversion data; the search converges to the bid with the best marginal return.
放量: once a term clears the confidence gate, Shepherd scales exposure in controlled increments — and holds the moment efficiency would slip.
Each keyword is an "arm." Shepherd keeps a Beta(α,β) belief about each arm’s conversion rate, samples from those beliefs, and spends on whichever it draws highest — so traffic flows to the best performer while still exploring the rest. As data accrues, the beliefs sharpen and allocation converges.
The same authorized SP-API connection powers two more engines — FBA replenishment planning and Amazon Brand Analytics (ABA) opportunity mining — so your inventory and demand decisions stay in sync with your advertising.
D̄ forecast daily demand · L lead time · z service-level factor · σ demand variability · C coverage period.
Surfaces high-demand search terms you under-capture, then feeds them back into bidding and creative.
Red hatch = plan finishes after the projected stockout date (won't arrive in time).
An agent rewrites titles to Amazon's latest 2026 listing policy and validates them before writing back through SP-API. The same studio generates storefront and A+ imagery sized to Amazon's specs.
Generates on-brand storefront and A+ imagery sized to Amazon's specs — you review the variants and publish the ones you want.
No black box. Shepherd applies established statistical techniques — the same families used across quantitative advertising and supply-chain forecasting.
Method names describe the algorithm families Shepherd draws on; exact parameters are tuned per account and category.
Each runs continuously on your campaigns. Every decision is data-driven, statistically grounded, and fully explained.
Shepherd connects only through Amazon’s official OAuth flow (Login with Amazon). You stay in control — and you can revoke access at any time from your Amazon account.
With your explicit authorization through Login with Amazon, Shepherd accesses advertising performance and account data needed to operate your campaigns — campaign, ad group, keyword, and target metrics; spend, sales, and conversion data; and product and listing information.
Shepherd does not request or store buyer personally identifiable information — no buyer names, shipping addresses, or contact details. We use only the data required to optimize advertising.
Solely to provide the automation you sign up for: adjusting bids and budgets, managing keywords, generating creative, and reporting performance back to you.
All data is transmitted over HTTPS/TLS and encrypted at rest. Access is least-privilege and need-to-know. Authorization tokens are stored encrypted and never shared.
We do not sell your data, and do not share it with third parties except trusted infrastructure providers that process it on our behalf under equivalent protection obligations.
We retain data only as long as needed to provide the service. Revoke access anytime from your Amazon account, or request deletion at support@manualstool.com.
