ContentKing

This tool has the ability to find SEO problems before they actually become a problem. It monitors complete websites for changes that have a potential to break it SEO wise. Its a must have tool!

That they weren't there when I needed them a couple of years ago. Honestly, no complaints about it. They have a great support team, if you have anything you don't like or miss, they think about a solution or fill up the developers backlog.

1) Website Overview: With Content King I can see the whole picture of a website: How the URLs are laid out, the health score of each page, and any problems/issues they may have (including broken links or pages that can't be indexed).

2) Track Changes: What truly sets Content King apart from any other scanning tool I've used is: Content King tracks changes. It's not a one-off scan, or merely a recurring scan. Content King keeps a running list of the changes for each page. If you're in the businesses of monitoring client websites and providing maintenance, this is a game changer.

Example: Content King notified me that several pages had gone "missing" on one of my client's sites. Turns out, they were consolidating several pages into one new page. However, they hadn't setup any 301 redirects to let Google know they weren't merely removed. Thanks to Content King, I was aware of the change and was able to advise my client accordingly.

3) Easy to Use: Content King has a wonderfully designed user interface. Feels fresh and new.

4) Website Migration: I haven't had the opportunity to use Content King to monitor the success of a website migration yet, but I'm looking forward to that.

5) Notifications and Reports: Content King notifies me of any major issues that pop up on a website, and they also send a weekly summary/graph so I can see an overview of what's going on with each of the websites I monitor.

6) Support: Very helpful and responsive support.

1) False Positives: Occasionally there are false positives where Content King reports a page as missing when the page is there. Luckily, when you view a page in Content King, it immediately re-scans/checks that URL, which can clear up any false positives right away.

2) Weekly Report Links: When reviewing the weekly report email, clicking the change in health and issues metrics goes to the website's dashboard rather than a view of specific changes that happened over the last week. I'd like to see that improved.

Content King gives you unique historical data by tracking the changes on a website. Usability and customer support are great. The company listens to the needs of their customers.

The number of features in Content King has grown over the time but it's still not enough to get rid of other SEO tools. It's a tool for monitoring but it would be great if they can build a full suite for analysis (combining data sources).

There's nothing like it on the market today. Depending on how you want to use it it's either a great tool to detect errors (e.g. sudden 301 changes) or to track content changes historically on the website. We use it for all of our clients larger clients to keep track of sudden content changes.

UX is great but could definitely use some improvement. It's changing every week so they're definitely active in updating the tool.
