Installs effortlessly and easy to add sources and have them automatically updated.
But a truly outstanding "extra" that comes with this plugin is the fantastic support. I'm a real beginner at this and required a bit of support -- not because there's anything difficult about the plugin but because I'm such a noobie. I exchanged about 10 support requests with Jean and I never had to wait more than about 45 minutes for an extremely helpful response. It seems to make no difference what time I needed help, he was always there and provided me with support that went beyond almost anything I've experienced.
I said I was a noobie, and that's true for WordPress, but I got my first personal computer in 1979 (and had been computing since 1972), and I know unusual support when I get it. This support is brilliant.
There are loads of uses for this great plugin. One thing I have done is, after adding several feeds to a "news" page on my site, contacting the owners of the sites that are all leaders in my niche, and telling them what I've done and explaining that anyone who clicks on one of the items will be taken directly to their site.
The response was extremely positive and resulted in my getting linked to from those sites. Because my site is still relatively young, having those back links from highly respected sites with large readerships helps to make my site more authoritative and is already, in just a matter of a couple of days, resulting in increased traffic for me.
I'm going to create an additional stand-alone site using this aggregator that will be a real resource for my niche.
Couldn't be happier that I came across WP RSS Aggregator.
