Proactive monitoring of client websites' SEO to identify important issues before they have a performance impact.

We run a SEO, PPC and Analytics agency and we rely on ContentKing to monitor our client websites and alert us to performance issues. Before ContentKing we would manually check websites periodically and often miss errors introduced by client developers that would cause a direct impact on a clients bottom line. ContentKing has been invaluable here and is at a price point that is affordable for an agency to absorb as a direct cost. I highly recommend it.

The API functionality is currently in an early form, I know that ContentKing is working on this and it'll be interesting to see what comes of the API but at the moment this is one of the few things we'd like to see changed.

Content King has saved us a few times, highlighting issues that would have caused a decline in SEO performance, such as: - We accidently blocked one of our sites from being crawled by search engines via the robots.txt file - An error caused canonical tags to change pointing to redirect URLS - During website migration Title tags changed from what they were previously Without ContentKing, we any have not noticed any of these until we randomly stumbled across them. With ContentKing we get notified within hours.

The ability to crawl websites in real time and then alert and track the changes is really what sets this tool apart from its competitors. Actually, there are no exact competitors at the time of this review, as all the competition are just website crawlers, but don't actually offer the proactive crawling, alerting and change monitoring that Content King does. Their customer service is second to none and probably the best customer server I have ever received.

Compared to other website crawlers, Content King is somewhat lacking in the number of different things it can check for. However, the real time crawling and alerting is what sets this apart from the others.

Value for money is really high. Multiple crawls per day, so you are notified of issues and updates right away.

It's a relatively new tool, so there are some minor features that are still in progress. However, the team is very responsive and helpful and updates often.

Can't believe there was a time we didn't use ContentKing and there are still agencies/SEOs/businesses out there that don't use it to monitor their sites.

Whether there's 5 people working on a site or dozens, we're in complete control of what changes when it matters. This is something we didn't have before ContentKing and now that we've experienced it, and seen the impact that it's had on our work – we can't live without it.

It is pricey but it's all relative. To us, it's not that expensive because of the value it provides to our service and our ability to deliver exceptional results for clients.

This software is helping me to take control of my site and the seo issues I didn't even realize it had. It is also allowing me to fix these issues quickly and track all the changes I've made. It audits my site regularly to make sure everything is as it should be and notifies me when something changes.

Ease of use. It is very straightforward and this makes it super easy to use for regular website and blog owners. You don't need to be an SEO Guru to be able to manage and improve your SEO on your site. Audits are run on your sites and you are notified of all possible SEO issues and you are able to sort them by priority as well as ignore those that you do not need to focus on or fix. Each suggestion is clickable and you can go right to the page or post on your site to fix what you need to fix. I test-drove more than 5 other SEO Tools this spring and Content King is by far the most user friendly and it does everything I want it to do. It also has the best customer service I've come across out of the tools I've tried.

The cost is a little bit steep for a blogger (small business). It is definitely worth it though and it is priced very competitively with the other SEO Tools I have test-driven.
