If your blog still loads slowly after image optimization, there are likely other factors at play. Excessive plugins, especially if poorly coded or outdated, can slow down your site. Consider removing unnecessary plugins or switching to lighter alternatives. Large CSS and JavaScript files can also delay loading, so minifying and combining these files can help reduce page load time. Server issues, such as high latency or limited bandwidth, can be another culprit. Upgrading to a high-speed or dedicated server may significantly improve load times. Optimizing these elements should lead to noticeable speed improvements.
