Welcome to the Q&A Forum

Thanks in advance for any help!  I have an existing website with content on a particular topic.  I have discovered a few similar expired URLs that might still get some traffic.  One in particular still has a number of valid links from other sites.  Would it make sense for me to buy those URLs (which are really cheap) and just use them to send that traffic to my site?  If so, am I better using a 301 redirect or having a home page on the new site that just mentions that the old site is expired, and that they might want to instead link over to my site?
