There is no definitive answer to this question as it depends on a number of factors, including the nature of your business, the competitiveness of your industry, and the quality of your website. However, a good average position in Google Search Console is generally considered to be between 1 and 3. This means that your website is appearing in the top results for a significant number of keywords. If you can consistently maintain a position in this range, it is likely that you will see a significant amount of traffic to your website.
There are a number of things you can do to improve your average position in Google Search Console. First, make sure that your website is optimized for search engines. This means ensuring that your title tags, meta descriptions, and header tags are all optimized for your target keywords. Secondly, create high-quality content that is relevant to your target keywords. This content should be well-written and informative, and it should be regularly updated to ensure that it remains relevant. Finally, build links to your website from high-quality websites. This will help to improve your website's authority and improve your chances of ranking well in search results.
