From a live website to an actionable case study

Current-page evidence

Capture the visible copy, headings, calls to action, pricing signals, links, page structure, and color palette from the website you are viewing.

Reverse AdSense lookup

Detect publisher IDs and inspect known domain relationships and ads.txt signals without treating an incomplete result as proof that no relationship exists.

Fixed 30-section analysis

Receive the same complete research structure every time, covering the product, users, pain points, business model, growth loops, differentiation, risks, and an MVP replication plan.

Registration and traffic signals

Combine domain registration data and available PubSpy traffic signals with the page evidence. Estimates stay labeled as estimates, and missing evidence stays unknown.

Keyword domain scan

On a Google, Bing, DuckDuckGo, Yandex, Yahoo, Baidu, Ecosia, Brave, Startpage, Qwant, Sogou, or Naver results page, the keyword's 20 common suffix domains appear in a card pinned to the right rail, each with its registration date or availability. One bulk lookup, no credits spent, and the card can be collapsed or closed.

Live, source-linked research

DeepSeek researches the public web while it analyzes. The report separates observed facts, cited external evidence, estimates, and hypotheses so you can judge confidence.

Follow up and export

Ask additional questions in the same case-study thread, then save the result as Markdown, TXT, HTML, DOC, or PDF.

Private account workspace

Saved case studies require your account. When you request AI analysis, the captured research evidence is sent to PubSpy and DeepSeek as disclosed in the privacy policy.

A focused website research workflow v6.6

Private case-study library

Each analyzed domain receives its own account-only case-study URL, so research remains organized and can be revisited from the website or extension.

Language follows your question

Keep the interface in English or Chinese while the report automatically follows the language of your initial prompt or latest follow-up.

Editable research brief

Use the built-in detailed framework, edit it for your niche, and choose whether signed-in analysis starts automatically when the panel opens.

Bounded failures and credit recovery

External calls use explicit timeouts and limited retries. If an analysis cannot complete, its reserved credits are restored instead of charging for a failed result.

Email OTP and Google sign-in

Use passwordless email codes, Google redirect sign-in, or Google One Tap. The extension and website share the same PubSpy account and credit balance.

Business and growth diagnosis

Study who pays, why they buy, how the product acquires users, how referrals could work, what likely drives revenue, and which claims remain unverified.

Evidence-aware conclusions

The report is instructed to cite public sources, explain inference, label MRR and traffic estimates, and say “unknown” when support is missing.

Credits and predictable pricing

Eligible new accounts receive 100 credits (up to three starter grants per IP address each month); daily claims add 10 (up to three accounts per IP address each day). Each analysis or follow-up uses 5 credits. Monthly, yearly, and one-time credit options are available.

AdSense and domain utilities

Keep the existing publisher-ID, related-domain, ads.txt, registration-date, traffic-signal, CSV, and link-extraction workflows beside the new AI analysis.

Reverse AdSense Lookup: From a Publisher ID to the Sites Behind It

A reverse AdSense lookup starts from a pub- publisher ID or a domain and returns the other sites that publish ads under the same account. PubSpy builds that map from the AdSense IDs and ads.txt relationships its extension reads on the pages you open.

The publisher domains dashboard lists the synced AdSense publisher IDs and the domains recorded for each one, sortable by registration date or latest monthly traffic. It only covers publishers PubSpy has synced, so a missing ID means "not in our data", not "no other sites".

Working the other way round? Run the free AdSense approval checker on your own domain, or install the extension to read the publisher ID on any site you open.

Reverse AdSense Lookup FAQ

What is reverse AdSense lookup?

Reverse AdSense lookup takes a publisher ID or a domain and shows the other sites using the same AdSense account, so you can map a publisher network instead of guessing from the homepage alone.

Can PubSpy find a publisher ID from a domain?

Yes. Open a site in the Chrome extension, and PubSpy reads the AdSense publisher ID plus ads.txt relationships so you can jump from one domain to the rest of that publisher's inventory.

Is PubSpy a free reverse AdSense tool?

The Chrome extension is free. Use it for publisher ID lookup, competitor domain discovery, and ads.txt checks without a paid seat.

How do I run a reverse AdSense publisher ID lookup?

Open the publisher domains dashboard, pick a pub ID and read the domains recorded for it, or open any site in the extension to see its ID and ads.txt relationships first. Coverage is limited to the publishers PubSpy has synced.

What does an AdSense publisher ID look like?

It is the pub- number on a site's ads.txt line, for example google.com, pub-1234567890123456, DIRECT, f08c47fec0942fa0. The same ID on several sites normally means the same AdSense account.
