Edgar is built for evergreen content publishing. You will be able to keep a library of your best content, put them into separate categories, and assign time slots for them to be automatically re-shared in the future. Random content can also be assigned to time slots, and you can even decide which categories will be included in random!
Currently Edgar does not support multiple images in a single post. Photos are also shrunk to a more mobile-friendly resolution. As a photography-centric company, we would love to be able to show our photos in a bigger size.
Edgar works best if you already have a good number of (or plan on keep adding more) evergreen content to avoid too much repetition. You wouldn't want to bombard your audience with the exact same content over and over again. This will of course be dependent on the frequency of your schedule as well as how refined your categories are.
In terms of the networks supported, Edgar currently works for Facebook, Twitter, and LinkedIn, but it doesn't seem like they will be adding more networks in the near future. So if you're looking for evergreen content sharing for Pinterest, Instagram, G+, or Snapchat, etc, you might be out of luck. (At the time I don't think service or products exist for these networks, though)
If you're a social media manager, you would know that the organic reach is ever-dwindling, and how important it is to re-use your evergreen content so more of your fans will be able to see your popular or effective content. We used to manually re-post content via Buffer, but it turned out to be a very time-consuming task and the content-management is cumbersome and inefficient.
Then came Edgar. By setting up a schedule to share our evergreen content automatically, we saved a lot of time and can get back to the most important task: create more quality content.
