It is called a funnel because when marketers show off the graph of what they are doing, it ends up looking like a funnel, thus the name. It could also be called a path or journey. This map shows the path customers take through a website. A funnel also lets you see if something on your site is a roadblock to purchase. If a large portion of your visitors take a particular path and none of them are converted to customers, you need to study that path. What is it about that journey that doesn’t lead them to purchase?
Website Sales Funnel Secrets to Triple Your Profits
I agree with you that Pulse CMS offers an interesting way to go, without databases. Before moving all my sites to WP over the past two years, I had always felt reluctant to use databases: but testing WP had convinced me to go ahead. Although I do not use it at this point (I played a little bit with previous versions), I bought a Pulse CMS license, if only in order to support that interesting project. I do not rule out using it for a site some day, at least experimentally.
Imagine just letting your website sit around for a year without ever editing its content. After a year, the WordPress CMS version is old and probably susceptible to hacking. Most website builders, on the other hand, are silently updated and maintained behind the scenes by the provider. As long as your password is secure, you have almost nothing to fear.
Although not so popular among the users, Craft CMS is an effective content management system. Some major examples of this are Netflix and Salesforce websites. It is a much more complex and developer friendly CMS platform that provides exclusive back-ends for your websites. Unlike WordPress, it does not provide front-end themes that you can use. Instead, you can use their templating system that is powered by Twig to design it yourself.
I’ve made some use of Kirby CMS. It’s a really well put together flat file CMS. It takes some coding out of the box to get it set up as desired, but then it’s a pleasure to use. Advantages of not having a database include simpler setup, and the ease of version control of the whole site. Statamic is a similar option, though I’ve not spent any significant time using it.
