Google Search Engine Optimisation involves a lot of factors but one thing everyone can do to boost your Google ranking is to write articles/posts/blog about your projects / jobs, add a picture and post onto your website. If your website is wordpress you can now add a plugin which also posts your article to Google my Business.
When Google scans your website and sees a new article and date change, this helps to keep your website fresh and updated. Then google knows your website is being managed on a regular basis.
So start writing about your job and add it to your website
