Norma, I just scanned your hub list and read a couple (Presidents, Civil War and one of the dog hubs).
1. Platforms - Because you write about pets, I'm surprised you don't have more readership. Usually that is a Top 5 view getter. Do you link to social media. Twitter and FB are enormously powerful for hubs. I use them and get a lot of views after I post on Twitter. I still don't have 50K views, but I do see an uptick over the past 5 months since I've been on Twitter.
2. You don't seem to be following a lot of people. I try to follow hubbers who write interesting material and who I feel are high quality. And I also try to support new hubbers. You don't have to follow everybody. I just use an unofficial criteria.
3. Regarding your Presidents hub, I do have a couple of suggestions. Let me know and I can email the ideas through HP.
Keep writing. The topics are interesting. I've only been a dog owner a couple of years, so I'm still learning.
