How to evaluate a streaming data provider

PeerLogix combines more than a decade of viewing history with inspectable public analysis and real applications in content strategy and recommendation products. The evaluation turns that foundation into a practical answer for your team.

You can begin with the public catalog concentration table and CSV. It includes the measure, source period and calculation. For a commercial sample, the brief below establishes the fields, access and permitted use needed for your specific job.

Write the decision before requesting the sample

Start with a sentence such as: “We need to rank these acquisition candidates for our U.S. service,” or “We need to test whether external viewing history improves candidate recommendations for new users.” Specify the decision owner and the current process. This gives the evaluation a baseline and prevents it from becoming an open-ended exploration.

Bound the request with representative titles, countries and dates. Include the kind of edge case you expect in production: a remake with a similar name, a series with multiple seasons, a small title or a market with sparse observations. Ask what can be provided within that scope. The size of the provider's historical collection does not establish the coverage in your package.

Scroll sideways if needed to read every column.

Confirm source permissions and the pilot terms

Before transferring a sample, ask how its observations were collected, which permissions support the proposed use, and whether records describe a household, device, account or person. Request the relevant documentation for de-identification, retention, deletion and changes in participation. Have the responsible privacy or legal team assess that account against your intended purpose and territories. A proposed license must be supported by the supplier's authority to provide the data.

Agree the sample fee, preparation time, access method, confidentiality terms and permitted evaluation outputs before the pilot starts. Establish who can access the files and what happens when the test ends. The coverage conversation resolves these terms for your project and gives both teams a clear start to the evaluation.

Ask for a package that can be understood

The data files should arrive with enough documentation to interpret them independently. Ask for a field dictionary, row-level definitions, date and time conventions, entity keys, coverage notes and an explanation of the population. A manifest listing filenames, sizes and checksums helps the receiving team verify that the intended files arrived intact.

Where a measure needs normalization, ask for the relevant panel totals or a documented denominator. Where titles are joined to services or corporate owners, ask for the mapping date and whether the relationship means ownership, availability, exclusivity or the source of observed viewing. Those meanings lead to different results.

Separate observations from derived measures and estimates. A title-day count, an overlap percentage and a modeled subscriber series should not share one vague “viewership” label. Derived outputs need a definition and revision policy. Estimates also need assumptions, validation and a way to express uncertainty appropriate to their use.

A PeerLogix evaluation focuses the viewing data, title metadata and analytical outputs on your stated task. Our data offering explains the delivery paths, while the methodology supplies the definitions your analysts need to interpret the result.

For a public aggregate example, inspect the catalog concentration table and CSV. It exposes the platform, current and prior shares, change and title count with a definition and source date. This shows how to check a published result. The field dictionary and access terms for a commercial evaluation are agreed separately.

Check coverage before calculating a trend

Build a simple coverage report for the requested title-country-date combinations. Separate a measured zero from missing data and from an entity outside coverage. All three may appear blank in a rushed dashboard, but they answer different questions. A title without a matched record cannot safely be called unwatched.

Check title identity using more than a display name. Remakes, translated names and different series can collide. Verify representative mappings manually and retain unmatched or ambiguous cases. For episode analysis, inspect the series, season and episode keys before interpreting a completion curve.

Review coverage through time. A sudden increase in observed activity could come from a larger panel, a changed source or corrected title mapping. Compare the change with the eligible panel total and any source notes. If a market's usable population is too small for the question, change the scope or report that limit.

Run the file and schema checks

Confirm that received files match the manifest and parse with the stated encoding and delimiter. Check field types, required columns, valid dates and duplicate keys at the documented grain. A duplicate event key is different from a household legitimately watching the same title on two days.

Test joins explicitly. Report the fraction of the requested title set that matches the metadata, investigate one-to-many mappings and decide how unmapped records will be handled. Summing after an accidental many-to-many join can multiply the audience without producing an obvious error.

Inspect revisions and late arrivals using a repeat delivery if the evaluation includes one. Determine whether corrections replace previous files or arrive as changes. Save the source version used for the evaluation so a later update does not silently alter your acceptance result.

Reproduce one meaningful result

Choose a calculation that matters to the actual job. For acquisition, reproduce an audience relationship or a title trend. For recommendations, compare a model with and without the candidate data on a held-out future period. For advertising, verify the supported audience definition and buying route before evaluating campaign outcomes.

When an external benchmark disagrees, align populations, units and time windows first. Minutes and households can move differently. A catalog ranking may include titles from several services, while another source measures a narrower device population. Agreement is useful only after those differences are understood. The measurement guide explains the main checks.

Evaluate added value against your baseline

Write down what changed because the sample was available. Did the team find a relevant audience it would have missed? Did a recommendation model improve useful ranking measures for the target cohort? Did a coverage gap rule out a project before the team committed engineering time? Each can be a meaningful result.

Separate predictive tests from descriptions. Explaining a past spike after reading the news is not a prospective forecast. A model should use only information available at the point of prediction, with dates for training, validation and final testing. Keep later revisions and outcome labels out of the historical feature set.

Assess stability as well as the average result. Examine smaller titles, new users, target countries and changing catalogs. A gain driven entirely by the most popular titles may have little value for a product trying to improve discovery elsewhere. Record tradeoffs rather than hiding them in one score.

Agree the use, delivery and operating terms

Before production work, confirm the permitted uses and the boundary between internal analysis and redistribution. Model training, customer-facing statistics, derived features and audience activation can require different arrangements. Ask about retention, deletion, access controls and obligations at the end of the license. Your team should review the applicable agreement.

Define the operating handoff: who receives files, who resolves mapping issues, how refreshes are monitored and how a breaking change is announced. A production evaluation should include the expected workflow, rather than relying on a sample delivered by a one-off process the team cannot maintain.

For audience products, the delivery partner must confirm supported matching, eligible inventory and current availability. For modeled commercial outcomes, specify the client data and validation needed. Viewing observations by themselves do not establish purchase intent, paid subscriptions or financial performance.

Finish with an explicit acceptance decision

Use four sections: passed checks, unresolved limitations, expected business use and agreed next scope. Assign an owner to each unresolved item. A qualified acceptance might approve one market or one workflow while excluding another until coverage improves.

Decide whether to proceed, extend a specific test or stop. An extension should answer a named remaining question. Repeating exploratory demos without a decision standard consumes time without improving confidence.
