This skill is deliberately not a universal list of "buying signals" with a heat score. That approach treats every signal as equally valuable, and it is not. ## The stance: a signal is only as good as its offer fit A signal is worth acting on to the degree it connects to what you sell. Someone attending a trade show is a strong signal if you sell trade-show services, because they have literally shown up in the room you serve. "They are hiring for a role" is a much weaker reason if it does not connect to your offer. So we do not hand out a generic heat score. We ask, for this specific business: 1. What does the buyer's world look like right *before* they buy from someone like you? 2. What observable fact marks that moment? 3. Can you actually detect it (a filter, a research check, a tool)? Find that fact, and you have your signal. The best ones are usually discovered per business, over time, not pulled off a shelf. ## Discover the signal (the useful work) - Look at the last few real deals. What was true about those companies right before they said yes? A tool they adopted, a page they built, a role they added, an event they joined. - Write it as a rule you can check: "sells to X," "runs paid ads," "has a public pricing page," "exhibits at Y." - Then decide how to detect it: a native Apollo filter, a research check Claude runs per company, or a tool. ## The signal menu the MCP can detect (all live-tested) Every signal below works as a **search filter** in people or company search, which is how you turn a signal into a list. All were validated live on a real Apollo account. Keep the offer-fit rule: a signal is worth using only if it maps to what you sell. - **Hiring for a role:** `q_organization_job_titles`, `organization_num_jobs_range`, `organization_job_posted_at_range`, `organization_job_locations`. To inspect one specific company's roles, use `apollo_organizations_job_postings` (1 credit per org). Caveat from testing: small and private companies often return zero postings even when active, so this signal fits larger or tech-forward targets far better than small firms. If it keeps coming back empty for your ICP, the signal does not fit your offer, the company is not necessarily quiet. - **Headcount growth:** `organization_headcount_growth_range` + `organization_headcount_growth_past_n_months`. Every company-search result also carries `organization_headcount_*_month_growth` inline, so you get the growth read for free. - **Recently funded:** `latest_funding_date_range`, `latest_funding_amount_range`, `total_funding_range`. - **Technology adoption:** `currently_using_any_of_technology_uids` (also `_all_of_`, and the `not_` exclusion). "Uses or added tool X." - **New in role (tenure):** `person_days_in_current_title_range` in people search. A fresh decision-maker in the seat. - **Job change:** `contact_job_changed` + `job_change_new_organization_ids` in contacts search. Returns a full change event (old title, old company, new company), so you know exactly who moved where. One of the strongest B2B signals: your champion just landed somewhere new. - **Company maturity:** `organization_founded_year_range`. - **Department size or growth:** `organization_department_or_subdepartment_counts` (for example, a marketing team of 5 or more). Some of these are labeled advanced filters and can return an upgrade-required error on free Apollo plans (all worked on the paid plan we tested). If one errors, it is gated on your plan, fall back to another signal. ### Website visitors (moved out of the UI, now filterable) **This used to be UI-only and no longer is.** If your team has the Apollo tracking script installed and Website Visitors access, `apollo_mixed_companies_search` will filter to companies that visited *your* site: - `website_visitors_from_domains` — your own tracked domains. - `website_visitors_from_past` — 1, 7, 15, 30, 60, or 90 days. - `website_visitors_domain_pages` / `..._exact_pages` — filter to who hit a specific path, for example `/pricing`. - `website_visitors_intent` — Apollo's computed low / medium / high from visit behaviour. - `web_page_view_counts` — **requires `website_visitors_from_past`**, because page views are only stored as time-windowed aggregates. Without a window it is silently ignored. - `show_new_companies_only` — first-time visitors only. `apollo_organizations_enrich` also returns `website_intent`, `website_last_visit`, `website_unique_visitors`, and `website_total_visits` for teams with access. This is the strongest offer-fit signal in the menu, because someone reading your pricing page has already told you what they want. It also needs no guessing: it is your own data. Gated on having the tracking script installed, so ask before promising it. ## What still lives in Apollo's UI only Worth knowing, but the MCP cannot execute these (see `../operator-context/references/apollo-kb-map.md`): - **Search alerts:** save a search and get alerted when new people match it. A standing signal feed. - **Workflows:** Apollo automates signal-to-action in the UI (Hit New Hires, Hit Recently Funded, Reach Website Visitors, Spot Companies Hiring for Specific Roles). Point the operator here; the MCP does not build workflows. - **Buyer-intent topics:** company results carry `show_intent` and `intent_strength` inline, but filtering by intent topic is UI or plan gated. - **Custom enrichment:** Clay integrates with Apollo and is a strong option for building custom signal workflows. Do not pretend it does not exist. ## How signals feed the rest - **Into targeting (Targeting and 2):** a good signal becomes a scoring rule or a filter, so it sharpens the list. - **Into prioritization (Iterate):** signal-matched leads are your High-priority tier, worked first. - **Into copy (Message):** the signal is often the opener. "Saw you're exhibiting at X" is a better first line than anything generic. ## No benchmarks You will see "signal-based outreach gets 3x replies" numbers everywhere. Ignore them. Whether a signal works depends on your offer and your market, and the only honest measure is your own positive reply rate on signal-matched leads versus cold. Test it, do not quote it. ## Common mistakes - Treating every signal as equally valuable. Fit to the offer is everything. - Adopting a generic heat score. It scores things that do not predict a sale for your business. - Gating on a timing trigger. A signal is a reason to prioritize, not a hard filter. Gating on "funded in the last 6 months" shrinks the list 20x and buries you among everyone else pitching them. ## Source & license This open-source skill is cataloged on AgentStack and links to its original source — we do not rehost the code. - **Author:** [jimmy-creatop](https://github.com/jimmy-creatop) - **Source:** [jimmy-creatop/apollo-operator](https://github.com/jimmy-creatop/apollo-operator) - **License:** MIT Install and usage instructions live in the source repository linked above. ## Pricing - **Free** — Free ## Security capabilities Automated source analysis of v0.1.0 — what this tool can access: - **Network access:** no - **Filesystem access:** no - **Shell / process execution:** no - **Environment & secrets:** no - **Dynamic code execution:** no *"Yes" means the capability is present in the source — more access means more to trust, not that it is unsafe.* ## Versions - **0.1.0** — security scan: passed — Imported from the upstream source. ## Links - Listing page: https://agentstack.voostack.com/l/skill-jimmy-creatop-apollo-operator-apollo-signals - Seller: https://agentstack.voostack.com/s/jimmy-creatop - Browse the marketplace: https://agentstack.voostack.com/browse --- Listed on AgentStack — the marketplace for AI agent skills and MCP servers.
