Common JavaScript SEO Concerns

JavaScript Load Time

Use our JS performance tool to check JS execution load time, with First Paint, First Contentful Paint, Page load, and the time it takes to finish all JS requests.

Incomplete content

JS on your website can hide some content, blocks with interlinking, which significantly harms the promotion of your site in the search engine.

JS Technical SEO Errors

JS can replace elements on your website that are important for technical SEO optimization, such as the page title and meta description.

Page Render Errors

Check on your website if your JS page is fully rendered - does the page take a long time to load? Do search robots see the footer or do they see all content blocks on the site at once?

JavaScript Redirects

Redirects configured with JS can significantly harm your page if they redirect without 301/302 server status codes - this can lead to the exclusion of a fully optimized page from the index.

JS SSR missed - Broken SSR

When comparing a page with JS and without JS, you may notice SSR errors when some content blocks disappear or the text/html ratio becomes 0, which has a bad effect on your SEO.

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 🔥

I'm responsible for SEO strategy for a really big website (10+ million pages). JetOctopus helped me to identify technical issues, deal with messy LOGs and organize data. Thanks to JetOctopus we've fixed technical issues, optimized our crawling budget, and grown traffic from 80k daily to 260k in 6 months. JetOctopus you rock!

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!
