Summary of skill metrics

The Summary section of the Analytics page displays an overview of the metrics available for the skill. For each metric, you have options to view infographic-style charts, grids, or other visualizations. Available metric data export formats are PNG or JPEG images for infographics, or CSV format for raw data.

Skill outage notification

On the Analytics page, the developer console displays a high-severity event banner when Alexa detects that the skill is experiencing an outage. For details about the outage, click Learn More.

Skill quality coach

Important: Amazon offers the skill quality coach feature as a beta. The feature might change as Amazon receives feedback and iterates on the feature.

The Skill quality coach analyzes your skill against common attributes of successful skills, and then generates a quality score and improvement recommendations. Use these recommendations to build high-quality Alexa skills that can increase customer engagement.

At this time, the skill quality coach is available for published custom skills in the United States (English) with enough monthly active users to measure customer feedback accurately.

Quality score

The Skill Quality Score metric is a composite score, measured on a scale from 0 – 5, that indicates the completeness of the skill and strength of customer feedback.

The quality score is based on the following skill attributes:

Rich multimodal and voice responses
Voice interaction model coverage and accuracy
Fresh, engaging, and personalized content
Skill endpoint health, such as reliability and latency

The quality score evaluates customer feedback based on the following input:

Customer stickiness, including number of engaged, repeat, and lapsed customers
Customer feedback, including ratings and reviews

Together these metrics produce a quality score between 0 and 5. The following table shows the relationship between the metrics and the score.

	Low customer feedback	High customer feedback
Less common skill attributes	0 – 1	1 – 3
More common skill attributes	1 – 3	3 – 5

Recommended insights

The skill quality coach provides Recommended Insights to improve your quality score. Each recommendation is based on your skill type and attributes and includes estimated effort to implement the improvement. To improve your skill quality, implement the recommendations and republish your skill.

The skill quality coach provides the recommendations based on the following input:

Automated evaluation of your skill against high-quality design features for similar skills.
Skill insights team that curates recommendations for select skills based on thorough evaluation of the skill.

To help improve the insights evaluation, you can provide feedback on the recommendations. Provide thumbs up if you agree and thumbs down if you disagree with a recommendation.

Skill activation and token retrieval metrics

For skills that use account linking, the Analytics page has an Account Linking section that displays metrics related to skill activation and token retrieval. These metrics are available for live skills.

To understand these metrics, first learn about account linking initiations and completions. For details, see Add Account Linking to Your Alexa Skill.

The following table shows the metrics that are available under Skill Activation. These metrics show data up to two days before the viewing time.

Note: For skills that don't use account linking, the console shows the Skill Activation section with Total Enablements as the only metric. There are no Account Linking or Token Retrieval sections.

Metric	Description	Skill types
Total Enablements	Definition of this metric depends on the type of skill. For custom skills without account linking, all Flash Briefing skills, and music, radio, or podcast skills without account linking, the metric represents the total number of unique users who enabled the skill. For smart home, video, and baby activity skills, the metric represents the total number of unique users who enabled the skill and completed account linking. Although some users might enable your skill, they might never launch that skill. Users who launch a skill count as unique user. This behavior can explain a difference between the number of times users enable a skill and the number of unique users.	Custom (without account linking) Flash Briefing Music, radio, or podcast (without account linking) Smart home Video
Total Account Linking Events	Total number of account linking initiations and completions.	Custom (with account linking) Music, radio, or podcast (with account linking) Smart home Video
Account Linking Completion Rate	Percentage of successful account links. The percentage is the total number of account linking completions divided by the total number of initiations. Available separately for account linking in the Alexa app (the Alexa-app-only flow and app-to-app account linking that starts from the Alexa app) and account linking in your app (app-to-app account linking and the Login with Amazon fallback flow).	Custom (with account linking) Music, radio, or podcast (with account linking) Smart home Video

Token retrieval metrics

The following table shows the metrics that are available under Token Retrieval. These metrics appear in near real-time (within a few minutes of being emitted).

Metric	Description	Skill types
Access Token Requests: Success Rate	Percentage of successful access token requests from the Alexa service to your skill's authorization server. For details, see Overview of the authorization code grant flow.	Custom (with account linking - authorization code grant) Music, radio, or podcast (with account linking) Smart home
Refreshing Access Token Requests: Success Rate	Percentage of successful access token refresh requests from the Alexa service to your skill's authorization server.

Access Token Requests: Error Responses	Number of error responses to access token requests from the Alexa service to the authorization server for the skill. For details on errors that come from OAuth 2.0, see Error Response in the OAuth 2.0 authentication framework specification. If the Alexa service receives an OAuth 2.0 error that it doesn't recognize, it displays it as an UNKNOWN_ERROR_CODE. A TRANSIENT_ERROR indicates that the Alexa service wasn't able to communicate with the partner service. For other error situations, Alexa returns a `null` error.	Custom (with account linking - authorization code grant) Music, radio, or podcast (with account linking) Smart home
Refreshing Access Token Requests: Error Responses	Number of error responses to access token refresh requests from the Alexa service to your skill's authorization server. For details on errors that come from OAuth 2.0, see Error Response in the OAuth 2.0 authentication framework specification. If the Alexa service receives an OAuth 2.0 error that it doesn't recognize, it displays it as an UNKNOWN_ERROR_CODE. A TRANSIENT_ERROR indicates that the Alexa service wasn't able to communicate with the partner service. For other error situations, Alexa returns a `null` error.	Custom (with account linking - authorization code grant) Music, radio, or podcast (with account linking) Smart home

Operational metrics

Use operational metrics to see how your smart home and video skills perform. You can download the data to troubleshoot skill failures and latency issues. For more details, see View Operational Metrics for Smart Home and Video Skills.

On the Analytics page, in the Operational Metrics section, the Discovery, Capability Directives, and Reporting State pages display the following metrics for device discovery, device control, query state requests, and proactive change reports:

Accuracy rate – Accuracy rate indicates the percentage of time that the response to a ReportState directive matched a previously sent ChangeReport event.
Latency – After Alexa sends a request to your skill, latency is the time in milliseconds until Alexa receives a response from your skill.
Success rate – Success rate is the total number of successful responses Alexa receives from your skill divided by the total number of requests Alexa sends to your skill.
User perceived errors (UPE) – Errors that cause friction to the Alexa user and compromise the user experience, such as when a skill doesn't respond to Alexa with the results of the user request to turn on the lights.

Skill performance metrics

Use skill performance metrics to view how well your skill is functioning.

Endpoint Latency – Use Endpoint Latency to see how responsive your skill is to user utterances. Skills with low endpoint latency have slow responses and cause friction for users.
Endpoint Response – The Endpoint Response metric shows the number of successful and failed responses your skill has over time. Skills that have no response confuse users and lower user satisfaction with your skill. If users aren't responding to your skill, your endpoint-response metrics reflect a low score.
Intent Confidence – The Intent Confidence metric shows how your voice interaction model is performing. The confidence setting options are high, medium, or low. A low confidence request from a user triggers a re-prompt instead of sending the utterance to your skill as an intent request, resulting in a poor user experience.
Estimated System Errors – The Estimated System Errors metric estimates the potential success of a conversation turn based on system signals from ASR/NLU and context. Use this metric to review utterances that frequently cause failed interactions and to view aggregate skill improvements over time so that you can modify your skill to further improve accuracy.

Note: The Estimated System Errors metric is available for high-traffic skills in en_US, en-GB, and de-DE.

Monetization metrics

Alexa has three payment models for paid skills and custom skills with in-skill products:

One-time purchase – A single transaction purchase that unlocks access to the skill itself or to premium content within the skill. For example, access to a paid skill or to a new level within a game. A one-time purchase doesn't expire.
Subscription – A purchase that offers access to your skill or premium-skill content for a period of time, charged on a recurring basis until the customer cancels the subscription. If you offer a free trial, after the trial period ends, access converts to a paid subscription.
Consumables – (For in-skill products only) A purchase that unlocks access to content, such as in-game currency or extra lives. The customer consumes and depletes the content, and might re-purchase it repeatedly.

The following table shows the metrics that are available under Monetization.

Metric	Description	Applicable types
Total Purchases	Total number of offers accepted for all purchases within a skill. For consumables, Total Purchases includes repeat purchases by the same user.	One-time purchases and consumables
Purchases	Number of offers accepted for each one-time purchase or consumable within a skill. For consumables, Purchases includes repeat purchases.	One-time purchases and consumables
Offer Impressions	Total number of times users heard the purchase prompt from Amazon, describing a skill or product and its price, and decided whether to buy. Offer Impressions includes both free-trial and paid offers. For consumables, this metric includes both the first-time purchase and repeat purchases of the same item. Offer Impressions doesn't include messages provided within the upsell directive.	One-time purchases, consumables, subscriptions
Offer to Purchase Conversion	The percentage of offer impressions that resulted in a purchase.	One-time purchases and consumables
Active Subscriptions	Total number of active subscriptions for your skill, including paid subscriptions with future expiration dates.	Subscriptions
Trial to Paid Conversion Rate	Percentage of trial subscriptions that became paid subscriptions.	Subscriptions
Subscriptions Started	Total number of new subscriptions.	Subscriptions
Subscriptions Ended	The total number of trial subscriptions that a user canceled or paid subscriptions that a user canceled. If a user cancels a paid subscription, the subscription remains active until it expires at the end of the billing period for the user.	Subscriptions
Churn	Percentage of active paid subscriptions that expired or that a user canceled.	Subscriptions
Offer Conversion Rate	Percentage of offer impressions that resulted in the user signing up for a new trial or paid subscription.	Subscriptions
Upsell to Offer Conversion	(For in-skill products only) The percentage of upsell impressions that resulted in a purchase. Upsell to Offer Conversion is available for the upsell directive only.	One-time purchases, consumables, subscriptions
Upsell to Purchase Conversion	(For in-skill products only) The percentage of upsell impressions that resulted in a purchase. This metric is available for the upsell directive only.	One-time purchases, consumables, subscriptions

Alexa Shopping Actions metrics

Alexa has the following categories of Shopping Actions for custom skills:

Add-to-Cart action – The customer requests that the skill add the product to their Amazon Shopping Cart. Later, the customer visits Amazon.com to make the purchase.
Add-to-Wishlist action – The customer requests that the skill add the product to their Amazon Wish List.
Buy action – The customer purchases the requested product during the skill session.
Recommend-products action – The customer agrees to learn more about products that your skill recommends.

Metric	Description
Add to Cart recommendations	Total number of product recommendations made within the skill.
Add to Cart conversions	Number of product recommendations that the customer added to their Cart.
Add to Wishlist recommendations	Total number of product recommendations made within the skill.
Add to Wishlist conversions	Number of product recommendations that the customer added to their Wish List.
Buy Action recommendations	Total number of product purchase recommendations made within the skill.
Buy Action conversions	Number of product recommendations that the customer purchased.
Number of product recommendations	Total number of product recommendations made within the skill by using the Recommend-products action.
Recommend products Add-to-Cart conversions	Number of product recommendations that the customer added to their Cart.
Recommend products Buy conversions	Number of product recommendations that the customer purchased.

Customer friction metrics

Use customer friction metrics to see how users interact with your skill. Alexa uses various user interaction patterns and other contextual signals to predict if a user experienced friction when interacting with your skill.

Note: The Customer friction metrics are available for high-traffic skills in en_US, en-GB, and ja-JP.

Customer friction summary – Use the Customer friction summary dashboard to see relative trends for your skill plus a list of frequent utterances that Alexa has identified as causing potential customer friction.
Barge-ins – Use the Barge-ins metric to see how often user interrupt an ongoing skill response. High barge-in rates could have causes, such as long skill responses, unexpected up-selling options, or not allowing enough time for a user to respond to a prompt.
Terminations – Use the Terminations metric to see the number of times users prematurely end a skill session. Premature termination causes include a user making a request that's out of scope for the skill, an incorrect slot recognition, or an incorrect use of Name Free Invocation.
Unhandled Requests – Use the Unhandled Requests metric to see the number of times your skill is unable to handle user requests. New user requests that might be relevant for your skill can contribute to these unhandled requests.
