## Performing Efficient Broad Crawls with the AOPIC Algorithm

This article explains how the Adaptive On-Line Page Importance Computation (AOPIC) algorithm works. AOPIC is useful for performing efficient broad crawls of large slices of the internet. The key idea behind the algorithm is that pages are crawled based on a continuously improving estimate of page importance. This effectively allows the user of the algorithm to allocate the bulk of their limited bandwidth on the most important pages that their crawler encounters.
