Typically, Google Ads can take up to 24 hours for approval, but in some cases, it may take longer if manual review is required. To speed up the approval process, make sure your ads comply with Google's policies by ensuring they do not contain prohibited content and have clear landing pages. It's also recommended to use relevant keywords and create high-quality ads to improve the chances of getting approved more quickly. Additionally, checking for any errors or issues within your ads before submitting them can help prevent delays. Please keep in mind that ad approval times may vary based on multiple factors, so it's essential to plan ahead and be patient during the review process.
