I’ve left the technical aspects of SEO to last but to be honest with you, I believe they should be first. If your website is beautiful and bountiful with well researched keywords and well-written content, it is will be of no use if the underlying structure isn’t sound.
You may need some help from your web developer if you don’t know your canonical from your cloaking and that’s why many businesses leave this bit well alone. Search will leave your site behind if you don’t keep up with the technical issues that could impede your site from being crawled and indexed.
HTTPS, site speed and mobile friendliness have all become critical to search success and they have two kinds of benefits.
1. They improve your user experience and that means that potential customers will stay on your site instead of bouncing away.
2. They are also key ranking factors since Google moved to mobile first in 2016 and declared a preference for HTTPS sites way back in 2014 ‘to keep everyone safe on the web’. Site speed on desktops has been a ranking factor since 2010 and since 2018 it has been a ranking factor for mobile search.
