Jetoctopus compiles ideas based on your crawl data. For example, it will suggest fixing pages by business impact or internal links you can build. The fact that it brings crawl data, search console, log files, and Google Analytics together makes it a tool you want to log in every day.

JetOctopus is a refreshing and new SEO crawler in the market of SEO tools. Its integration with log files and Google Search Console is very useful. JetOctopus has features that other competitors lack, it's fast and it is loaded with graphs and data tables, much more than the average other SEO crawler. JetOctopus pricing structure is also very attractive for freelancers and agencies, as you really don't pay more than you need to as well as apply one-off top-up if the situation calls for it. I truly enjoy using JetOctopus in my SEO toolbox. Give it a try!

JetOctopus is one of those tools that was previously missing from the market. Simple to use on the one hand and a powerful optimisation tool on the other. The speed with which it crawls the pages is admirable. Also the clarity of the reports and the indication of the next steps to be taken is exceptional. I highly recommend it 🔥

JetOctopus is probably one of the most efficient crawlers on the market. It's fast and incredibly easy to use, even for a non-SEO. Its most convincing selling point is that it has no crawl limits, no simultaneous crawl limits and no project limits giving you more data for less money. If you are working on a huge database-driven website, you'll definitely find it a money- and time-saver.

I have to say that I absolutely LOVE the visualization oriented functions of Jet Octopus. I'm a veteran with crawling tools, started with Xenu, and have tried dozens of various crawling solutions from free to enterprise. I even helped Raven Tools develop their site auditing tools as a product manager. The typical problem with technical SEO is that tools just spit out more and more data in table after table. It's a super power to be able to see literally dozens of different slices of data visualized in charts, graphs, venn diagrams and more. My wife came to see what the "AMAZING" thing I was shouting and pointing at on my screen when I went to export an internal link analysis from Jet Octopus and it opened the data directly in Google Sheets. I've been waiting AGES for a tool like this that visualizes technical SEO data and makes my workflow easier by improving the tired CSV download slog.

Jetoctopus is very powerful at logs analysis in connection with crawling data. What I personally like most of all: 1. It's much more pleasant to crawl big websites in cloud than with the help of desktop crawlers even on a very powerful computer. 2. They have a very quick and powerful Segmentation. They have regexp and it's possible to segment literally everything!). 3. Overlapping of data from logs+crawling opens a lot of new opportunities for deep analytics and effective technical SEO optimization. 4. High-quality technical client's support. 5. Price is many times cheaper than the competitors offer.

I love that JetOctopus allows you to perform very thorough analyses of both the internal and external linking structures of your website. I would recommend adding the crawler to your SEO toolkit. Jet Octopus is great at visualising the data, including that from PageSpeedInsights and means that you can see the average score of all of your pages including whether or not they have a poor, average, or a good score. JetOctopus will certainly make your next website audit a lot quicker and easier, and more meaningful!

All data in one place with streamlined and helpful presentation. Quickly gives the opportunity to identify technical SEO potentials. From internal linking to pagespeed, everything can be measured in one place. Predefined visualizations already give the necessary rough overview. Own log files and real keyword data directly from Google Search Console can be matched with own crawl data. The crawl can be set up quickly and comfortably including custom data extracts from your own pages. The JO-team and support are very friendly and helpful. Highly recommended.

JetOctopus offers a performant web crawler and gives a really great summary of the problems found on my website. In a couple of minutes, I was able to identify critical issues, and it took more minutes to solve them. The interface is neat the filtering features allow me to deep dive into the SEO analysis and do some on-page optimisations. Definitely another addition to my SEO toolbox that will keep my website healthy.

Right now the number one thing I am impressed with is the ease of generating reports that include the columns of data I need. Screaming Frog for example provides you with details on 301s and 404s but do they give you an easily exported report that provides the URL impacted, Where it is Linked from, and Where it is Redirecting to? No they do not. You have to go one by one and copy and paste that detail. Very frustrating but with JetOctopus I can download the report and quickly assign it out for resolution. I still have a lot more to evaluate and I am interested in doing an article about the product, but I need to live in the tool a bit longer.

Small agencies have to move away from #technicalSEO #crawlers that are glorified data dumps. There's just not enough hours in the day to wrangle massive spreadsheets. Cut to the chase by doing the heavy lifting and identifying priority work. @JetOctopus has figured that out.

@JetOctopus has helped me to visualize and evaluate all the problems related to the content. Stunning metrics related to the internal links. Needless to say a client of mine has tripled the budget on SEO after seeing the reports from @JetOctopus

We use JetOctopus for everyday SEO-routine and for controlling current website status. Speed of the tools is unseen. I appreciate the real time information about logs with intuitive interface. With JetOctopus at hand I have control on crawl budget and indexation of rozetka.com.ua Working with such a big website as rozetka.com.ua it is necessary to compare changes and results of experiments really quickly so to avoid dramatic decreases. JetOctopus is one of the best SEO tools that I have ever used.

At the moment I like: 1. The volume of scanned data. It is either hard or expensive to do that with the help of the existing crawlers. You have a good balance in this case. 2. The agreggated information. The amount of the provided information is quite enough and you can see at once where and what the problems are. 3. The possibility to download practically any report as well as a detailed one for subdirectories.

JetOctopus is impressively powerful crawler. I was excited by a number of reports and filters, by user-friendly interface, speed of crawl and a separate satisfaction I am getting from your guys focus on customer. Linking explorer – absolutely unique feature on the market – was launched by JetOctopus team in 3 weeks after my conversation with their tech lead. And this tool gives as exhaustive info on the url as it is ever possible.

I'm using JetOctopus from the first demo version. Before JO, I used DeepCrawl, but now I fully switched. Why? Because JO has: - useful fast reports in clear interface, - datatable in which you can filter any data - possibility to analyze logs, - GSC data and crawl together. I saved a lot of time on hard joins in SQL with all these data. I fall in love with this tool and hope they will add more useful features in the future. With the help of JetOctopus we've got 300% increase of Preply.com indexation. Just within 1 year.

I have never seen such SEO expertise. and true involvement of JO team in our big and complex website. We've just started our partnership but I truly belive in this tool and approach.

Very nice and easy tool do audit your site for SEO. Easy of use this tool to audit how your site is working for SEO (meta tags, http statuses, internal links, site speed and so on). You can then improve your site for search engine bots. Additional tool - log analyzer can help you to check what and how search engine bots index your site. It's very helpful to use your crawl budget well.

I love JetOctopus due to the three main reasons:
1. First, the vision behind JetOctopus understands the value of Data Science and Analysis for SEO.
2. Second, JetOctopus is a log analyzer, SEO Crawler, and data analysis, blending, aggregation, and visualization technology at the same time.
3. Third, JetOctopus improves the perspective of SEOs, and the brains behind it care about SEO in real. It is not just an SEO software that is marketed. JetOctopus is a Swiss-army-knife for SEOs that love innovation.
I know that I will see JetOctopus more and more in the field of SEO. And, as a pioneer in the Technical SEO Crawler, Google Search Console Data Analysis, and SEO Log File Analysis technology, I am sure that SEOs will be moved forward by JetOctopus' vision.

JetOctopus is my go-to crawler for Technical SEO audits for Google.
From crawl budget waste to 404s, or unwanted (non-SEO) pages which are negatively impactful when indexed, JO has me covered. It has become a very powerful alternative to other tools available like Screaming Frog or Deep Crawl.
The new SEO Efficiency feature, where I can combine all the Crawl, GSC and Logs data into one place, is second to none. The awesome visualizations available allows me to communicate much more clearly to any internal team about the good, the bad, and the ugly items within the data, in a super easy graphical way that is perfect for presentations. Both SEO problems and opportunities are clearly summarized so you can create action items that have the biggest impact.
I highly recommend this affordable 5-stars, super fast crawler and log analyzer to anyone looking to make visual sense of their SEO datasets.

You can also have it all in one place, fully merged, visualized and ready to draw data-driven conclusions, ready to deploy and provide optimization guidelines and that right away !
