How can I add 'www' to my website address?

as you can see here it should be www.makerlab-electronics.com

anyone help me how to fix this one?

Hey, [email removed]Niceeee! Welcome to Shopify Community!

I’d love to help. The domain without the www prefix is currently your primary domain, this is why that’s showing on Google search results and on the URL bar whenever anyone visits your website. For the www.makerlab-electronics.com domain to display instead, you’ll have to set it as your primary domain. You can do this by following the steps below:

  1. From your Shopify admin, go to Settings > Domains.
  2. Click the domain that you want to make the primary domain.
  3. Click Change domain type.
  4. Select Primary domain.
  5. Click Change domain type to save.

I read your website’s meta description on the screenshot you shared and I thought I’d mention it. It’s a great summary of your online store and it perfectly expresses what your business is all about, however, it may not always capture the interest of potential customers. The main thing I noticed is that it doesn’t have a call to action. A call to action is a phrase, such as “Shop now” or “Browse our products,” that encourages people to click on your website. Consider rewriting your meta description to strengthen your SEO or search engine optimization, which can help grow your business and bring customers to your store. Here’s a blog post that gives great tips on how to write an effective meta description: How To Write Meta Descriptions.
