Deciding whether to keep your existing site or start a new one depends on several factors. If your current site has a significant amount of high-quality content, established backlinks, and a strong brand presence, it may be better to improve and optimize it. However, if your site suffers from severe technical issues, high spam scores, or a poor reputation that can't be easily fixed, starting a new site might be a more effective long-term solution. Assess the overall health and potential of your existing site before making a decision. At some point I was also thinking the same but I have solved many problems for the website and now It up and running.
