Turn publisher setup problems into practical next steps
Use ADXProbe to fetch public advertising files, inspect website-readiness signals and combine matching scan evidence with your metrics. Reports distinguish observed findings from unknowns and show where manual investigation is still needed.

Investigate a publisher performance change
Check filled versus total ad requests
Use counts from the same reporting period and confirm how the platform defines the metric. The ratio alone cannot identify the cause of no-fill.
Compare viewable and measurable impressions
Keep the reporting definitions consistent. This calculator uses supplied counts rather than measuring an ad on your page.
Organize the next investigation
Combine matching-domain scan evidence with the metrics you enter. Missing data remains unknown instead of becoming a fabricated health score.
Questions about ADXProbe
Can low fill rate alone explain lower advertising revenue?
No. Revenue can also change with impression volume, auction prices, deductions and other factors. Investigate matching reports before attributing the change to one ratio.
Does the ad-size preview test a live placement?
No. It is a labelled local placeholder. Check production slot width, responsive size mapping and real ad delivery separately.

Useful evidence. Clear limits.
Choose a tool, enter your own numbers or public website information, and review the result. Every report separates what was observed from what still needs a human review. No invented approval scores.
Your inputs stay yours.
Calculations and pasted-text checks run in your browser. Live scans send only your supplied public domain to the configured backend. We never ask for Google passwords, account access or API keys.
Publisher tools: methods & instructions
AdX Readiness Checker
Checks HTTPS, homepage text, recognizable policy links, ads.txt and indexing directives. A fetched link is evidence of a link, not a review of its contents.
AdSense Website Readiness
This advisory review cannot inspect your AdSense account, verify content rights or determine approval. Review Google policies manually.
Ads.txt Live Checker
Retrieves the root /ads.txt over HTTPS. Syntax does not prove seller authorization. Network failures and missing files are reported separately.
Ads.txt Syntax Validator
Paste plain text to check three required seller fields, the optional certification ID and supported ads.txt 1.1 directives. Runs locally.
Ads.txt Generator
Use the advertising-system domain and seller account ID supplied by your monetization provider. We never generate or verify real seller IDs.
App-ads.txt Checker
Fetches /app-ads.txt from the supplied developer domain. App-store developer website links, ownership and package identity need separate verification.
Sellers.json Checker
Checks a domain’s root /sellers.json, or pasted JSON. Confidential entries may legitimately omit name and domain; confidentiality alone is not evidence of fraud. Files over 2 MB are explicitly refused by live scans.
SupplyChain Validator
Supports SupplyChain 1.0 objects and common bid-request wrappers. Validates ver, complete, nodes, asi, sid and hp. Structure alone cannot prove supply-chain authenticity.
GAM Tag Inspector
Static heuristic inspection of pasted Google Publisher Tag code. The code is never executed. Dynamic paths, comments and variable-based sizes may need manual review.
CPM Calculator
CPM = advertising cost ÷ impressions × 1,000. Choose a currency shared by all money inputs. Reverse calculations solve cost or impressions.
eCPM Calculator
eCPM = revenue ÷ impressions × 1,000. Uses realized revenue rather than a guaranteed auction price. Reverse calculations are supported.
Page RPM Calculator
Page RPM = estimated earnings ÷ page views × 1,000. Page views and ad impressions are different denominators; this tool calculates Page RPM only.
CTR Calculator
CTR = clicks ÷ impressions × 100. Use matching reporting periods and scope. This calculator requires clicks not to exceed impressions.
Fill Rate Calculator
Default definition: filled ad requests ÷ total ad requests × 100. Platforms may define fill differently; use matching request metrics, not impressions as a substitute.
Ad Revenue Calculator
Daily opportunities × assumed fill rate × CPM ÷ 1,000. If impressions are already served, set fill to 100% to avoid counting fill twice. Monthly projection uses 30 days.
Viewability Calculator
Viewability = viewable ÷ measurable impressions × 100. Measurable impressions are those where viewability could be measured; they are not the same as all served impressions.
CPC Calculator
CPC = total advertising cost ÷ clicks. Choose a calculation mode to solve for CPC, total cost or clicks using a consistent currency.
Ad Size Preview
Visual placeholders only: 300×250, 336×280, 320×50, 320×100, 728×90, 970×250, 160×600 and 300×600. Large previews scale down to fit; actual dimensions stay visible. No ads are requested.
Monetization Health Report
Rules-based suggestions use matching live scan results from this browser session and metrics you supply. No fabricated score, AI claim or official eligibility decision. Thresholds are diagnostic heuristics, not Google requirements.
Independent readiness assessment — not an official Google approval decision. Technical findings cannot establish content compliance, traffic quality or monetization eligibility.
Good questions. Straight answers.
Can ADXProbe approve my website for AdX or AdSense?
No. Google or the applicable authorized process decides approval. ADXProbe offers independent technical checks and manual-review guidance.
Why do live checks need a backend?
Browsers restrict many cross-origin website requests. A configured scanning backend retrieves permitted public files safely. Without it, live tools show “Live Scan Not Configured”; local tools remain usable.
Does a valid ads.txt file prove seller authorization?
No. Valid formatting only establishes that a file follows supported syntax. Confirm the account ID and commercial relationship with the advertising provider.
Are revenue projections guaranteed?
No. They are calculations from your assumptions. Actual demand, geography, viewability, consent, invalid traffic deductions and reporting definitions affect outcomes.
Can these tools rank in Google or appear in AI answers?
Useful original content and sound technical SEO support discovery, but rankings, indexing and AI recommendations are never guaranteed. Separate tool pages can be developed later with their own unique explanations and functionality.
