Newly released court files from the antitrust case against Google provide a closer look at how the company’s search system is described in internal and expert testimony. The material touches on indexing, ranking models, data collection, and the role of user behaviour. The filings also note that the information does not necessarily describe Google’s current operations, since some of it was prepared by external witnesses.
What the Index Holds
The search index is presented[1] as more than a catalogue of web addresses. According to the documents, it keeps record identifiers, timestamps, and signals about site reliability. Spam scores[2] appear alongside those details, giving Google a way to decide which pages to scan and how often they should be revisited. Popularity measures also factor into that decision, creating an additional layer beyond page content alone.
Ranking and Page Quality
PageRank[3] continues to feature in the descriptions as a core signal, though the records emphasise that the quality of the page itself carries more weight. This suggests that while links remain part of the process, Google pays closer attention to what is on the page when assigning a position in results.
Data from Glue and Machine Learning Models
Another element referred to is Glue[4], which collects search queries and behaviour to generate ranking inputs. Interaction data, such as clicks, time on page, and quick returns, is used to assess whether results satisfy the query. These inputs then feed into statistical models. One such model, RankEmbed[5] BERT, is described as being trained on months of search activity combined with the scores of human evaluators.
User Behaviour as Input
The filings underline that user activity is considered at every stage of the process. Data is used to decide which sites should be crawled, how the index is arranged, and how results are refreshed to reflect newer information. It also helps track which advertisements attract attention, which in turn influences how ads are matched and delivered.
A cycle is outlined in the records: as user data helps[6] improve search quality, more people use the service, which increases ad revenue. That revenue can then be used to secure traffic and improve systems further.
Interaction Data in Training
Click and query data, sometimes called user-interaction data, is a major source[7] of training information. It includes which results are chosen, how long users stay on a page, and whether they return quickly to the results page. Training sets are said to cover more than a year of such behaviour, giving Google an advantage over smaller rivals who lack the same scale.
Signals from Chrome
References also appear to data gathered through the Chrome browse[8]r. Court exhibits describe visit records from Chrome as one of the measures of popularity, along with link anchors between pages. These signals feed into ranking in ways that show how different types of usage data are combined. Some of the details could not be fully verified in court, but the filings confirm that browser activity is among the inputs used to inform search results.
