This should be pretty obvious to any developer but I’m amazed how many times this fails.
If you build a Blog/CMS/Community Portal/Webapp or Website you should have a search functionality for your users. However that search should not return all the image assets for the site as part of the results.
Upon searching a site recently for the keyword “careers” I got 137 results. 120+ of them were indexed results linking to the image assets of the forum before any content links were listed that would take me to the “careers” page.
If the images within the site are actually fairly important – that’s fine. Add those results after the actual content results.
