I've used both these plugins and they are both premium. They seem to do the same thing and I would like to put them one VS the other. Scribe SEO is made by copyblogger, but seems not to be very useful for content marketing. Squirrly SEO, on the other hand, seems to have better user experience, but it's not made by a big name in content marketing. Have you used them? Which do you think is better? [UPDATE] Squirrly SEO has straight a to the point checklist of what you have to do to improve on-page SEO. And it is in real time. Another thing to consider is Scribe SEO doesn't have an Inspiration Box and it costs around $90 / month. Squirrly SEO costs about $19.99 / month.
