For a long time HTTPS felt like something people associated mainly with checkout pages, account areas and websites handling sensitive information. If a small business website was mostly content, it was common for HTTPS to be treated as optional. The technical argument for encryption was already there, but the practical process often added enough friction that it was easy for people to delay it.
Let’s Encrypt changed the tone of that conversation for me because it removed a lot of the old excuses. The certificate itself was no longer an awkward cost item. Renewal could be automated. Installation could become part of the normal server setup rather than a separate administrative task. Once that happened, HTTPS started to feel less like a special feature and more like the default state a website should be moving towards.
Why The Old Process Slowed Things Down
The earlier SSL process was not impossibly difficult, but it was clumsy enough to create delay. Certificates had to be purchased, validated, installed and renewed. If a client did not understand the value, the conversation could easily become about cost rather than protection. That was especially true for smaller websites where nobody was entering card details or logging into a private area.
The problem with that way of thinking is that it treated encryption as only being about the most obvious kind of sensitive data. A website request can still reveal what somebody is reading, which pages they visit and what form data they submit. Even when the content is public, the connection should not be casually exposed. The web had been moving in that direction for a while, but the operational burden slowed adoption.
The Practical Change
What made Let’s Encrypt interesting was not just that the certificates were free. It was that the process could be automated. On a server I control, that changes the decision completely. If a certificate can be issued and renewed through a predictable command, HTTPS becomes part of the deployment process. It no longer has to be a separate task someone remembers months later when a certificate is close to expiring.
That matters in agency and client work because repeatability is often more important than any single setup. If I know how HTTPS is being handled on one server, I want to be able to recreate the same behaviour elsewhere. A consistent process reduces the chance of an urgent certificate problem appearing at the worst possible time.
What I Would Still Check
Moving to HTTPS is not only about installing a certificate. Mixed content needs checking, redirects need testing and canonical URLs should be reviewed. Any hard-coded asset paths can create small problems after the switch. Analytics, search console settings and third-party integrations may also need attention depending on the site.
That is why I would still treat HTTPS as a small migration rather than a single button press. The certificate is only one part of the work. The website needs to behave consistently afterwards, and that means testing how pages, images, scripts, forms and redirects respond once the secure version is live.
Retrospective Thoughts
Retrospectively, Let’s Encrypt made HTTPS feel normal for websites that might previously have delayed it. That is the important part. It did not make security automatic and it did not remove the need to configure a site properly. It did remove a lot of the friction that made people treat HTTPS as something to think about later.
For me, the decision became straightforward. If a website can be served securely without creating unreasonable cost or maintenance work, there needs to be a very good reason not to do it. Let’s Encrypt made that position easier to defend, especially for smaller websites where the business case had previously felt harder to explain.
