Also consider forums where people hang out and discuss various subjects. Asking and answering questions is a great way to increase your own knowledge as well as sharing the knowledge you already have. Being active in these forums (Quora for example) is another way to get good exposure. Remember though, no Spamming, or your time there will be short.
Writing a good piece of unique quality content will rank better in the search engines and it will also encourage people to like it, share it etc. People will not do that with your content if they see it as poor quality. Let’s be honest here, if you were reading something that you thought was pure garbage, would you read and share it? Of course you wouldn’t and neither would I.
The days when internet browsing was done exclusively on desktop PCs are long gone. Today, more people than ever before are using mobile devices to access the web, and if you force your visitors to pinch and scroll their way around your site, you’re basically telling them to go elsewhere. Ensure that your website is accessible and comfortably viewable across a range of devices, including smaller smartphones.
