Many sites have png favicons that may be stored anywhere. You kind of need to parse the HTML to be sure, and I guess that's what the DDG service does.

- anais9 5y agoFor sure, but even a lot of those sites maintain a favicon.ico to support legacy crawlers/systems - then for those that don't (i.e. trigger onError), falling back to DDG's icon is an easy way to skip all that parsing.
