Hi Miren, I feel that you should not delete those older post just yet. There usually is something in them that applies to the present with just a little rewriting. I just recently had such a situation and rewrote parts of the post. Guess what happened? I received a comment along with a request for more information. This may also work for you. You may want to give it a try. :-) Frank

See how you can repurpose them as a first step Miren!

I think it best to keep them. I deleted one post some time ago and wish I hadn't.

No such thing as wasted posts in this case, keep them. The popularity of products and topics runs out eventually 9 out of 10 times. Erasing them will actually inhibit your site's authority. You should aim to keep adding and adding, not erasing.

I wrote a post back in 2014. That was to help users solve a particular problem them. I was getting over 1k readers from search engines on that post. At one point, everything sent down below zero. It appeared the system that caused the bug was upgraded by manufacturer so that like almost got the issue resolved once and for all.

I didn't delete the post at all

About 2 weeks ago, the same problem resurfaced, this time on a different technology. Again, there was a huge spike in traffic. Over 1.3k daily readers from search engine.

I got lots of list signups. The traffic lasted for about 4 days. Now below 100 daily readers from search engine.

So you should really be careful when thinking to delete old post

I never delete my old blogs .. I update mine

I am just revamping my 13 year old site and coming across some very old and outdated posts and articles. I either:

1. If it is no longer relevant at all, delete the page and 301 redirect the url to another more relevant page (or the homepage). I also remove it from Google via webmaster tools.

2. If it still has historical or archival interest, I will add a note at the top of the page dating the article whilst explaining why it is still there.

3. If there is a newer version of a product or if the page can be updated to make it more relevant, I will do just that (and maybe add an "updated: 2018" note).

If a page has a lot of "link juice" or people linking back to it, you don't want to lose that : )

If the topic at hand is relevant to your niche, I would re-work the posts. Maybe search and see if there are new keywords that are related to your existing content. I personally would only delete if the content is completely off topic from your focus, ie site about health and your posts is about jewelry.

I've no experience or knowledge about such things but I would imagine that if they attract just the slightest traffic, why get rid of them. They may become popular again and unless you've no room for new ones, leave them alone. As a reminder if nothing else.

Instead of deleting them why don't you rework them. That way you still have your keywords and you have more experience to show them a different way and possibly gain more audience. It also helps you to become a stronger authority in your niche.
