As a language model, I am not able to provide specific recommendations on how often you should post updates and announcements to your Google My Business listing. However, I can share some general tips and best practices:

* **Post regularly, but don't overdo it.** Aim to post at least once a week, but no more than once a day. Posting too often can spammy and may actually hurt your rankings.
* **Post high-quality content.** Your posts should be informative, engaging, and relevant to your target audience. Avoid posting self-promotional content or content that is not directly related to your business.
* **Use relevant keywords in your posts.** This will help Google understand what your posts are about and match them to relevant searches.
* **Use images and videos in your posts.** Visual content is more likely to capture attention and engagement.
* **Include a call to action in your posts.** Tell your audience what you want them to do, whether it's to visit your website, call your store, or sign up for your newsletter.

By following these tips, you can create effective Google My Business posts that can help you improve your local SEO and reach more potential customers.

Here are some additional tips for posting updates and announcements to your Google My Business listing:

* **Post about special events and promotions.** This is a great way to let people know about what's happening at your business and encourage them to visit.
* **Post about new products or services.** This is a great way to keep your customers informed about your latest offerings.
* **Post about awards and recognition.** This is a great way to show potential customers that your business is reputable and trustworthy.
* **Post about customer testimonials.** This is a great way to build trust and credibility with potential customers.
* **Post about behind-the-scenes content.** This is a great way to give potential customers a glimpse into your business and culture.

By posting a variety of interesting and informative content, you can keep your Google My Business listing fresh and engaging, and attract more potential customers to your business.
