    - fast, continuous updates

    - tracking of improvement

    - good team behind it who know what they are doing

    - pricing


    nothing significant, most issues I have identified are on the roadmap now which is positive - that said its still early days

    Been using this for quite a while on a project website and it works incredibly to deliver insight into what has changed, what is broken and more - it has been developed by an SEO team so its a content marketing SEO tools first which is exactly what was needed. Love the fact it always crawls!

    Solid product / Great UI / Fast updates / Awesome support / Good price



    ContentKing is a no brainer if you want to make sure your websites runs flawlessly and without (SEO) flaws. You can have a good website, but without solid SEO your website will be good at best and not great. ContentKing can help you (your website) become great!

    Unique and advanced technical analyses, easy to use interface


    The pricing structure is not based on a flat 'per site' but instead on number of pages which can be hard to calculate

    I'd recommend Contentkings if you are looking for an easy way to scale site auditing. The tool does some really great and unique checks like finding out which pages are missing from the sitemap. I also loved the feature to find out missing (visual) analytics from pages.

    This is as close to a Google real time crawl emulator as you'll get!


    Some terminology takes a little bit of understanding/learning

    The ContentKing software has grown in its value immensely since I first came on as a beta customer.

    The interface is super user friendly and email alerts for any potentially concerning changes the real-time crawler finds is so cool. If you act on the email alerts CK stops any technical SEO disasters before they ever happen!

    Great product. Glad to see folks pushing the boundaries of what SEO software can be. The change tracking, saved my bacon several times <3.


    ¯\_(ツ)_/¯ haven't found anything yet. I'd love an agency account but I think they are working on that.

    I've been using this for some time now. I recommend all my clients get setup on it and it has saved the day in a lot of situations. It picks up changes faster than a human or running your standard crawl software in intervals and that alone is a great value to companies. Having crawl data of your site that is always up to date provides more value than you know, it is one of those things that you don't know you need it until you have it.

  • Pros: 

    Great real-time SEO tool that keeps you on top of any website changes that can affect your organic search visibility


    Sometimes hard to find and filter some common issues, but they're constantly improving the UI

    I've been using ContentKing for a while now and it's really helped me stay on top of any changes that are made to my clients' websites. Any time a client makes a change to their site that could negatively affect their SEO, ContentKing lets me know which in turn enables me to stay on top of the issues and not face unexpected surprises at the end of a month. Highly recommended to agencies that manage multiple clients, as well as in-house SEOs working in multi-team environments.

  • Pros: 

    It makes sense, it's useful for the marketer, it creates clarity



    ContentKing is an actual part of the work process, it's not just a nice to have tool. The fact that it touches on many different parts of the optimisation process. As an audit tool it has all the things a platform needs. But the real power lies underneath. It makes visible what for many stays hidden.

  • Pros: 

    The most helpful hands-off SEO tool I've ever used - you set it up and it lets you know the second your site has an issue.


    None to mention - development is ongoing and timely, so lots of new features on the horizon to look forward to.

    Onsite SEO has always been inherently problematic in that it's almost entirely reactive. You don't typically notice issues until they're already affecting your site.

    ContentKing tackles that issue, IMO, quite effectively: It monitors your site for changes in real time and alerts you as soon as anything bad happens.

    For example, we had a mixup while pushing a site update and an entire directory of content ended up blocked by our robots.txt. Normally it would've taken days or even weeks for us to realize that search engines weren't crawling the pages in that directory, but ContentKing notified us within literal minutes of the change and saved us a huge amount of potential missed traffic.

    Every SEO I know has experienced a situation where one small (usually inadvertent) change resulted in serious site issues. The accompanying panic and scramble to diagnose/fix aren't fun. And that's why I like ContentKing so much - it takes care of the little things so I don't have to, and frees up my time to focus on the bigger picture.

    Super easy to use, great support


    Price not based on a flat “per site” but on the number of pages. Calculating the total investment isn't easy.

    As a content creator/marketer, this tool is fantastic! It’s easy to use; the price is very reasonable when compared to other tools in the market. I recommend ContentKing if you’re looking to be more productive and efficient in your SEO audits and optimization work. It saves a lot of time and effort – and I already told that it’s so easy to use?

  • Pros: 

    Real time, Unique insights & Data.


    UI was clunky, its improving all the time, and I currently have no complaints with i

    I really like this software. The real time data insights it gives you are invaluable, but when managing multiple clients is where it comes into its own.

    ContentKing enables me to more productive with my current clients, and provides an extra layer of "SEO Security" that I had been looking for. IE: Now I feel way more informed, even with my minor clients.

    Ever had a client change URL structure and not tell you mid week? It happens. CK will tell you instantly, and keep an entire change history of your URLs = no more losing data/disasters as long as their site is set up in ContentKing!

    peace of mind. now nothing goes haywire on my website without me knowing. the prioritization is awesome too. 2 grateful thumbs way up!


    CK is so feature-packed that it almost feels like too much machine for my small website. best suited for agencies, or larger websites id say

    Been using CK for a half year now (not sure why that isn't an option on PH). I still dig Kevin, CK's friendly on-boarding mascot. He pointed me in the right direction until I learned the ropes then gets outa my way once I got there. And he's still good for a joke or two once in a while.

    CK has saved me so much time that I would normally spend sifting through the pages manually checking to make sure nothing was off. Can't imagine running my business without it now.

  • Pros: 

    The tool to monitor and improve your websites and to be sure you don’t have to worry about negative surprises.



    We use this tool already for more than a year and this helped us to improve our websites. And also, to be sure that we would find out if something on the websites was changed which could have negative results.

  • Pros: 

    Affordable, effective, handles scaling well


    Can seem quite "weak" compared to Deep Crawl on some points

    When I signed up to CK, I thought it was a Deep Crawl killer. I was wrong. They're different products, marketed at doing different things.

    Deep Crawl is more of a deep, sophisticated analysis that's "on demand", whereas CK is proactive and alerts you to changes before any potential damage is done.

    I feel like you still need both products to succeed at on-site SEO. CK is a must-have for large sites where new pages/posts are added daily, and changes are frequently made. It's important to keep track of editors - to ensure no mistakes happen. In addition, Deep Crawl is needed as it does dig a bit further and catch things that CK would miss, or doesn't crawl for.

    IMO, get CK and get the daily updates and constant monitoring. Use deep crawl for an audit every 2-4 weeks.

  • Pros: 

    - very useful to keep keep big websites healthy according to G seo guide

    - easy to use and understand


    - missing keywords positions reports

    Very nice tool for observing changes on their own pages, that is what developers changed at the last deploy and competition in reverse engineering what they do.

  • Pros: 

    Great UI (Our team love it) / Cloud Based / Pricing / Frequently updates / Constant Crawling



    We've used Content King for a couple of months and the team have been really supportive, quick to respond to requests and happy to work with our use cases to implement additional features.

    We're super impressed and the pricing is competitive with other tools that don't offer the "continuous crawling" which stands out for this product. We're in the throws of rolling this out across our entire client base.

    Keep your website data in real-time monitored. And improve your SEO results directly via the handy WordPress plug-in. Great tool!


    No Majestic data yet, but other SEO tools have the same issue. It would be nice to also monitor the authority of a website as well.

    It's really great to work with this tool. Especially if you have a problem, you get quick feedback through the chat function. This is technically and professionally supported by ContentKing. What is an advantage compared to other SEO tools..

    Simple interface / Great features / Keeps you aware of where you stand with each page.


    Agency pricing is a little costly when trying to start out.

    If I had the funds, I'd have ContentKing scanning every one of my sites and my clients. It's an awesome tool.
