Hi,
It's been 3 years since I stopped recording episodes but my website is still a podcast website.
Now I want to redesign the website to make it a aggregator of a specific industry that I work in.
It will be similar to https://www.classcentral.com/ but for my industry.

Essentially we will create mostly blogs and also eventually a daily newsletter. (revenue model would be affiliate income)

My question is how do I redesign the website without affecting SEO.

We rank for a lot of keywords and we get about 50k visits per month.

I want to redesign the website without affecting this.

Also, I primarily use elementor for the design of the site but now that I've learned html, css, javascript and some other frameworks. I want to incorporate some CSS to the website and javascript too.

I assume that I am supposed to stage the new design and stop posting new content when the website is undergoing a revamp. But how do I do it in a structured way without affecting the security and SEO..

Thanks

  1. Ads.txt Manager
  2. Advanced Google reCAPTCHA
  3. Ajax Search Lite
  4. All-in-One WP Migration
  5. All-in-One WP Migration Unlimited Extension
  6. Delete All Comments of wordpress
