Oncrawl’s SEO Crawler is the fastest way to monitor and analyse a website’s indexability, structure and content, regardless of its number of pages.

Oncawl SEO Crawler gives you access to all strategic data in one easy-to-use space.
For example, you can scrape data whilst running your crawl to pull out information like AMP implementation, product stock status and structured data. The crawler also allows you to monitor your tech solutions easily and keep track of changes that will impact or affect your business goals.
With this tool, you can also store and save all of your crawls in one place without the worry of any restrictions and, in turn, gain access to hundreds of indicators that relate to your site’s quality of content, performance, indexability, and so much more.

The Advantages and Disadvantages of Using Oncrawl
Like with any new tool, you need to be able to understand both the pros and cons of using it, so here are some advantages and disadvantages to Oncrawl.
The Advantages of Oncrawl
- The Features – There are so many quality features in Oncrawl, with three main ones that you can utilise every time to make your crawling and SEO much more accessible.
- Speed – Speed is something that Oncrawl doesn’t do half-heartedly. Oncrawl is known as one of the fastest crawl tools on the market due to its ability to process up to 300 URLs per second.
- Massive Reach – Oncrawl can support all kinds of sites, big and small, with up to millions of pages simultaneously and still not slack on speed or efficiency. I find it to be one of the most effective crawlers when working on large websites.
- Made For Experts, By Experts – This tool will help professional SEOs and consultants with their technical needs and a community full of experts in that field who are ready and willing to help you.
The Disadvantages of Oncrawl
- Pricing – Compared to other tools, it is on the higher end of the market price-wise, which means it is not as accessible for all SEOs and agencies, but the price reflects the quality of a product and its performance.
- Learning Curve – When handling some of the more technical, advanced options, this tool may mean you need to contact the support team or spend additional time getting to know each of the different areas and their capabilities.

Would I Recommend Oncrawl?
As we’ve seen in this Oncrawl review, the tool does have it all, and it is pretty challenging to find disadvantages to it. Oncrawl is reliable, fast and full of valuable, powerful integrations to use and navigate around.
Finding a tool that gives you everything you need to succeed in technical SEO and is not overly complicated or full of jargon can be complex, but this tool has it all and then some.
Yes, the price point is high if you just want to use it for freelance or personal use, but for what you are getting in that package deal, along with the capabilities of Oncrawl as a whole, I’d say it’s an investment that is well spent!
