Depending on your hosting setup this should be easy. Just purchase an SSL certificate, install on your web server, and make sure your site loads permanently in secure mode. (Look for the green https or lock icon to the left of your domain name). Services such as Let’s Encrypt make this easier than it’s ever been, and this is a proven ranking factor. Cloudflare offers free SSL certificates to their users, even if your website is made with WordPress. It's very easy to get signed up and configured. Reach out to us if you need additional support.
Everyone checks out their competition, right? Well take a look at the backlinks they’ve got too, and you’ll usually find a few that you can get as well. Use Moz OpenSiteExplorer or Google Search Console’s “Links to Your Site” section to find this information out. Once you’ve got the backlink information from around five of your competing websites, get all the data in a spreadsheet, and arrange it into groups of different links. E.g. directories, press, blogs, social or spam.
Then think about going after the same links that your competitor is going after to increase your chances of success!
