Google's job is to show users the most relevant and up-to-date results based on their search query. Quality online directories are just one great way to ensure your business in those local results.
A Localsearch Online profile can certainly help with your SEO. It does so by being a quality backlink and by being a trusted review platform.
What is a backlink? Part of Google’s assessment of your website is to measure your expertise, authority and trust (E-A-T). A backlink is a link on a website linking to your own website. This helps to show Google you’re a legitimate, trustworthy business, which is similar to how reviews will help.
What your customers say is almost more important than what you say about yourself. So when they review your business positively, it shows the search engine they can trust you and others can too.
So, is your business on localsearch.com.au?
