Questions & Answers

As answered by people managing SEOLinkMap and Cert Decoder.

What's the story behind your product?

Cert Decoder's answer:

I built certdecoder.com over the weekend for my own needs. Sometimes in my work, I need to verify and check certificate details.

Which are the primary technologies used for building your product?

SEOLinkMap's answer

Ubuntu Linux, NGINX, MySQL, PHP, jQuery.

Visualizations are delivered using CytoscapeJS and eChartJS

Our code is auditable, using raw math and Information Retrieval principles.

LLM is only used to 'smooth out' the caveman-speak sentences as the system reviews the calculated data.

Cert Decoder's answer:

certdecoder.com was built using just JavaScript and HTML—simple, fast, and with all processing happening locally in your browser, so no certificate data is sent to any server

How would you describe the primary audience of your product?

SEOLinkMap's answer

We aim to cover 5 basic user types... SEO agencies, in house SEO teams, Content Marketing teams, Solo Consultants, and independent Website Owners.

SEO skill level does not matter since our data is delivered as hard stats and numbers, as well as visualizations and charts for stakeholders, and plain speak narratives for non-experts to understand what the data presents.

Cert Decoder's answer:

certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.

Why should a person choose your product over its competitors?

SEOLinkMap's answer

A mix of lower price and superior quality of data usually does the trick, but many people prefer our cloud based solution without fiddling with software or consuming local bandwidth and resources.

Cert Decoder's answer:

Simple, fast, and reliable. Some similar tools can’t even decode basic certificates. I rigorously tested my tool with many real-world certificates and covered several edge cases where competitors fall short.

Who are some of the biggest customers of your product?

Cert Decoder's answer:

certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.

What makes your product unique?

SEOLinkMap's answer

The statistical rigor applied to reaching determinations means that we do not pre-define what is "best" in SEO. The analysis determines what works and what does not for individual SERPs. It is how we are able to lay out your entire website in a visual network chart according to relevancy.

Every geeky detail is available for real backup when strategizing with stakeholders, and broken down into plain speak that explains what the stats reveal so anyone can understand.

    Why? Because I built certdecoder.com and couldn’t find a decent place to submit it. So I said screw it — I’ll build my own. With blackjack and hookers. - Source: dev.to / over 1 year ago
