Google has put out a checklist for improving mobile websites. The search engine recently made several ranking changes for sites not configured for smartphone users, so you may want to pay attention.
The list is broken down into three main steps: stop frustrating your customers, facilitate task completion and convert customers to fans. Don’t worry.The points under each one are more specific.
For step one, there are tips related to removing extra windows from all mobile user-agents, providing device-appropriate functionality, testing, etc.
For step two, tips get into ptimizing crawling, indexing and the searcher experience and optimizing popular mobile persona workflows for your site.
For step three, tips are about considering search integration points with mobile apps, investigating/attempting to track cross-device workflow and brainstorming new ways to provide value.
