Ask Should I use DNS prefetch for affiliate merchant domains?

[Brajet]

Using DNS prefetch can help your site load faster when you link to affiliate merchant websites. DNS prefetch means the browser prepares the connection early before a user clicks the link. This reduces delay when the page opens. It is useful if many visitors click those links often. Still, adding too many prefetch links can slow things down instead of helping. It is better to use it only for important merchants. Have you seen real speed improvement when using DNS prefetch on your pages?

DNS prefetch can give a small but noticeable improvement, especially on affiliate pages where users frequently click external merchant links. It doesn't make the page itself load faster, but it reduces the delay when someone opens those external sites, which improves perceived speed and user experience. However, the impact is usually subtle, not dramatic, and depends on how many external domains you're linking to. It works best when used only for a few high-traffic merchant links, because overusing it can add unnecessary overhead without real benefit.
