Myth: Account aggregation is just screen scraping.
Reality: Screen scraping refers to the gathering of data via HTML. Account aggregators rely on pure HTML for less than 30% of the sites they support. Instead, they gather data via fixed format files, similar to what is provided in a direct feed.
Myth: Screen-scraped data, and other data gathered via Web sites, is inaccurate and unreliable.
Reality: There is almost no correlation between the data format and the accuracy of the data. Highly accurate data is available via Web sites, through HTML and fixed formats, as it is via direct feeds, but any methodology can also produce poor data quality. It is the rigor of the institution providing the data, and the sophistication of the aggregation technology, that ultimately determines data accuracy, not the data format.
