I use a blog on my business website. I write about 2 articles/week. I started this in 2012. Some of these articles have just 100-200 words and don't receive very much search engine traffic. Should I keep my old blogposts? I was thinking to create a page about a certain topic and merge all the old posts on that page. Example: I have 10 old articles/blogposts about social media. I create 1 new page about social media. I copy the content of the 10 articles on the new page. I redirect the old articles to the new page. I now have a 4000 word page about social media. Good idea/bad idea for SEO? What do you think?
