Actionable Bullet Points from BrightonSEO

• Lemonly - infographics, keep mobile in mind and try to make infographics responsive as readership is still very large on mobile devices.
• Headlines - should be aiming to get people to read worthwhile, educative content 
• Dumbing-down that won't last - need a more long-term vision for content production
• People don't share profanity so try to exclude from titles or structured data.
• AB testing headlines - this is something you can do to see if the title is better for shareability. Also experiment with social structured data.
• Most Facebook users browse on their mobile so ensure any shareable content is going to be viewed well on them.
• "Newsjacking" - Wayne Rooney salary calculator as an example - almost forces a link if users have to see it to understand the story 
• The importance of collaboration - most affirmed generation in history

Pete Handley's SEO audit checklist

Although the slides do cover most, here's some more notes... (also, Pete is awesome)

• Canonical tags - trailing slashes may be an issue so make sure they're covering all possible dupe content issues
• Optimise - mapping keywords to pages is something you should do and be on top of.
• Sitemaps - use different Sitemaps for measuring indexation levels on different areas of the site. Here you'll be able to knuckle down any indexation issues on a section/page level much easier.
• Alt tagging - not used as much but ensure you do it, as well as making relevant filenames
• HREF Lang - it's a complex process. Having an XML sitemap over inline tagging makes life easier

• Authorship markup won't necessarily work,  but more authors on a page tend to increase residual trust
• Domain names do make a difference for authority
• Naturally attracted attention - sales worthy language - review and number language, eg "3 reasons etc"
