It’s a good idea to update your blog regularly to keep your content fresh and to attract and retain readers. How often you should update your blog will depend on your specific goals and audience. If you’re running a business blog, you may want to post new content at least once or twice a week to keep your audience engaged and to help boost your search engine rankings.
If you’re running a personal blog, you may be able to get away with updating it less frequently, perhaps once or twice a month. Ultimately, the key is to find a posting schedule that works for you and your audience, and to stick to it as much as possible.
