How to deal with lot of old content that doesn't drive traffic - delete?

[Marketing-Omoda]

Hi community, i hope someone can help me with this,

We are migrating our e-commerce site next februari. I'm preparing the content migration. For a large part exact copies of our product listing and product detail pages will be migrated. 
However, we also have a lot of old blog content, which is, because of seasonality and trendiness, outdated and doesn't drive traffic anymore. It actually is just worthless content. (Not only as a traffic driver, this also counts for extremely low to none internal driven traffic (both internal search and internal navigation).

We have about 4.000+ blogs of which about 100 drive the most traffic (mostly incited by e-mail and social campaigns and internal navigation promoted on important category landing pages during some period.

Is it a bad signal to search engines to delete these old content pages? I.a.: going from a content-rich to a content-poor site?
Off course I will migrate the top 100 traffic earning content and provide proper redirects to them

Hi there,

It is not a bad signal if you are in fact deleting low-value content that does not drive traffic or back links. Content is becoming more of a 'quality over quantity' game (thankfully). If you are making your site more efficient for Google to crawl and condensing SEO authority (link juice) and pointing more of that your more 'important' pages, you could actually see an uptick in business from organic search. I will note that you should look at your blog posts to see if there are opportunities to update them to make them more informative and/or more current.

If any of the posts you are removing have inbound links or rankings, you will want to properly 301 redirect them. Take a look at these resources where sites removed old pages and maintained site performance or even saw an uptick. The content audit portion of your analysis is going to be crucial, you must be sure you are not deleting content that is driving traffic.
