How to recover Organic traffic?

[Sell a Car With High Mileage]

We have a tech blog which is 3 years old. Back then when we started it. It was getting 400-500 visitors per day. We have published new content since then but haven't much cared about the traffic. Now the blog is getting almost 100 visitors per day. What can we do to recover the lost traffic?

The blog has almost 6k backlinks referring from almost 90 domains.

To recover lost traffic, consider refreshing old content with updated information, improving on-page SEO, and optimizing for user intent. Focus on building topical authority by clustering related articles and ensuring fast page load speeds. Analyze backlink quality and acquire new ones from reputable sources. Additionally, promoting your content through social media and newsletters can help drive engagement.
