Got a site that was abandoned about ten years ago. Used to get 5K-10K organic traffic with domain authority in the 40s range. Now authority score is 5, and organic traffic less than 100 per month. No manual penalties. Just no new activity and no content in the past decade.
I've started redesigning the site and cleaning up the content - specifically, setting up the pages based on the new Wordpress theme, improving images, removing the Adsense ads, adding internal links, etc. The content is mostly interviews (average length from 1500-2000 words) and tips (average length 600-1000 words), so it doesn't have the issue of thin content. I've submitted the sitemap and now seeing a small uptick in the Google search console but it still has a lot of pages not indexed in Google. I figure to clean up existing pages first and resubmit in search console, then start creating new content.
If you have a dead site that lost the love of Google, how will you make it back into Google's love?
Thanks
