You probably visit at least a few sites that are relevant to your business on a regular basis, so why not join the conversation? Commenting doesn’t necessarily provide an immediate boost to referral traffic right away, but making a name for yourself by providing insightful, thought-provoking comments on industry blogs and sites is a great way to get your name out there – which can subsequently result in driving more traffic to your own site. Just remember that, as with guest posting, quality and relevance are key – you should be engaging with other people in your niche, not dropping spam links on unrelated websites.
Do you remember how you reacted the last time you tried to visit a site and it wouldn't load? Like most people, you probably exited the tab and moved on. If your site load times are slow, it won't rank high in search results. Not to mention, the customer experience won’t be positive if your site isn’t up an running in seconds, three seconds to be exact. For every second longer that goes by, your abandonment rate will skyrocket, leaving unhappy customers and potential sales on the table.
