I only have a small selection of hubs so far. (7 to be exact.) Before hubpages started putting hubs into 'unfeatured' status due to low engagement, they all had that lovely little symbol next to them showing they were featured...Then a few of them were unfeatured due to low engagement and it drove me crazy. lol. I put all this work into hubs and it was frustrating to me that people weren't even able to find them on my profile anymore... How are they supposed to get more engagement if people can't even find them? It maddened me a bit at first... But going back and editing them, I found it wasn't really that difficult to get them back into featured status.. It really just required adding a few more photos and a little tweaking here and there.
I've managed to get all but one back into featured status.. I have yet to go back in and edit the last one because I've been trying to focus on writing new hubs and not obsessively maintaining the few I have. I do plan on editing that last one though. After I reworked the couple that were unfeatured I found that traffic did rise on them, so I trust that the people at hubpages know what they're talking about. :)
My next goal is to try and get one of my hubs picked as an editors choice. At first I wasn't impressed with this new system, but now I find it quite helpful. The little 'helpful hints' they put up in the right hand corner when you're writing a hub makes it easier to make sure you hit everything you need to in order to ensure your hubs get featured.
If I ever write a hub that I'm not completely in love with, I might let it fall by the wayside if it's ever unfeatured in the future, but for right now I have such a small collection of work in comparison to a lot of people on here, that I want to try and maintain them as best as I can.. I find the only challenge is to not get to caught up in spending all my time on the few hubs I do have and spending enough time writing new ones.
However, if I ever get a hub that becomes unfeatured due to low quality, I would be all over that in a split second. lol. I'd rather have a small collection of really well written hubs than a ton of them that aren't quite up to par!
