As a business owner, it’s important to understand the massive benefits of using SEO website crawling and auditing tools.

With these SEO tools, you can identify where your largest areas of improvement lie, how the search engines are accessing your site, or to identify gaps in your content by crawling a competitor’s site.

While crawling and auditing your log files is just one of many tactics used by businesses and professional SEOs to understand their sites, it’s an important one that should be part of any marketing strategy worth it’s salt.

For an idea of just how important this is to your business, Baastian Grimm, an instructor at Semrush Academy and online marketing consultant, explains:

To that end, we’ve compiled the best website crawling and auditing tools that you should investigate using to improve your website’s organic traffic from SEO.

ScreamingFrog

Screaming Frog is most likely the most popular SEO website crawling and auditing tool available online.

Built by the team at Screaming Frog, an agency based in the UK, this SEO spider runs off your own machine and can be very powerful when used with custom filters.

You can crawl as different user agents, exclude or include robots.txt, and so much more.

With the free tier you can crawl up to 500 URLs. On the paid tier (just £149 per year) you can crawl unlimited URLs, schedule crawls, crawl as different user agents, crawl Google AMP URLs, and so much more.

Plus they’ve updated the interface and it’s now more beautiful and functional than ever.

In fact, SEER Interactive wrote a phenomenal guide to it.

Botify

Botify

Botify is a relatively new tool on the market.

Different from ScreamingFrog, it is a subscription-based model that gets you to access to their SaaS (Software As A Service) tool that crawls your site from the cloud (aka not on your personal machine, so you can do other things as your crawl happens) and gives you in-depth reports with clear actions to take next on your site.

Botify markets itself as “a leading enterprise SEO platform”, which means that it is built specifically for enterprise in-house SEO teams (and their agencies) to track changes over time and help drive reporting and actions to improve organic traffic.

Their Intelligence tool also helps you “prioritize your SEO tasks by greatest impact,” which means you’ll work more often on the right things that will move the needle on organic traffic.

DeepCrawl

Deep Crawl

DeepCrawl is our enterprise crawling tool of choice.

This tool is more expensive than the above two mentioned SEO crawling tools. DeepCrawl goes deep into your site and provides you with recommendations to help you prioritize your technical SEO.

Pricing is based on the number of pages you crawl each month. You can adjusted as needed, as you go.

We’ve used this on sites with 10 million+ pages and it worked a charm. It takes our site’s SEO to the next level. Highly recommended.

Splunk

Splunk crawler

Splunk is actually an IT and server admin tool, but it can be very powerful when applied to your log files for SEO.

Using Splunk, you can identify how the search engines are actually crawling your website and make optimizations from that data. It’s not a cheap tool when used for the full power, though there is a free version that can get you started.

If you are working on any level of enterprise website, though, it could be worth your money.

A great post was written here on Moz about using Splunk for Technical SEO.
