I have a personal blogger blog that I've been posting to since May 2005 and which now has 461 posts. Back when I started the blog it used to make me about £80 a month through Adsense (that didn't last long) and then until about a year ago it had a steady 2000 uniques a month, which I realise isn't a big deal, but some posts did rank No.1 for some very specific niche stuff. I never built the blog as anything other than a dumping ground for content from projects I was abandoning, but there are some reactive posts to niche gaps I saw begging to be filled, but on topics that are now probably covered by Yahoo Answers. So it's worth noting that the blog doesn't really have any one theme or topic. So should I continue to let the traffic flow grind to a halt, or do you think it might be worth picking a few of the better performing posts and give them a bit of a link-boost using GSA SER? After all, what have I got to lose? I have never built a single link to this blog and SEMrush declares it has having 1,700 backlinks from 23 domains (on 20 IPs).
