A good brand has a clear focus and knows their target audience.
It is of my opinion that if we're going to change the name, it should be one of the following:
Webmasters - just stripping the "Pro"
Search Engine Optimization
The argument for Webmasters has been made very clearly already. Below I present an argument for Search Engine Optimization.
The primary argument against changing the name to Search Engine Optimization, or SEO, is that we cover a lot of other things outside of the discipline.
Looking the front page right now, however, I can't find a single question scrolling all the way down that isn’t about SEO, a Google product, or doing something else within the context of optimizing a site for search engines.
Here’s one that at face value might be about more than SEO:
Minify at the web server level or at CDN level?
The goal appears to be about optimize their website performance using WP Rocket plugin. They’re obviously looking to achieve sufficient Web Vitals for Google since that's a rankings factor now. This is what makes it on topic for our site, and why StackOverflow sent it to us.
In my experience, albeit limited compared to all of you, the questions that are not about SEO that get covered here belong on (or would be a better fit for) either ServerFault, AskUbuntu, or SuperUser.
Brief aside: Many of these get flagged and closed, and many do not because we answer them very well. That said though, I see no reason why those questions can't be migrated to one of the aforementioned sites after one of our own has gotten first dibs.
Looking at our guidelines:
What topics can I ask about here?
Pro Webmasters is a site for asking questions about operating and
managing your own website. Questions here are commonly about, but not
- Search engine optimization (SEO)
- Web and email hosting
- Internet marketing
- Website management (e.g., analytics, ads, URLs, etc…)
As far as branding goes, you could call the site "Search Engine Optimization” and get away with covering all of the other topics on that list. Someone that identifies as an “SEO” surely encounters all of them throughout the course of their career.
Overall, my argument is that if SEO is the majority of what we cover, then for all intensive purposes, we’re an SEO site.
Search Engine Optimization has a clear focus, clear target audience, and encompasses the vast majority of what people ask questions about on our site.
Webmasters is the easiest solution, considering we can't change our subdomain and/or logo.
Something to consider I thought of as finishing this answer:
Technical SEO I think is actually very fitting to the skillsets that most of us possess and questions we answer. Technical SEO is pretty much anything these days that requires any sort of code, or an understanding of networking, http protocol, etc.
Technical SEO is the process of ensuring that a website meets the technical requirements of modern search engines with the goal of improved organic rankings. Important elements of technical SEO include crawling, indexing, rendering, and website architecture.
There are also really not really any existing sites/communities focused on Technical SEO.
