Most conversations about SEO start with keywords. Which ones you're going for, how competitive they are, whether you've got a realistic shot at ranking. But before you get into that next keyword-focused conversation, there's another question worth answering first: how strong are your credibility signals?
Website credibility basically boils down to whether a person (or search engine or LLM) landing on your site can work out who you are, what you do and if you know what you're talking about.
TL;DR
Credibility signals are the things that tell a reader (and a search engine) who's behind your content and if you're trustworthy.
Five of the easiest credibility signals to address: author information, internal links, homepage clarity, your about page and structured data.
Google's own guidance for content creators asks whether it's obvious who authored your content. It's a stated expectation, not an SEO theory.
Fix these and you improve how people, search engines and AI tools read your site, all at once.
Why website credibility is a search problem, not just a brand one
Google's guidance for content creators asks site owners to consider the Who, How and Why.
The Who is the one that matters most. Is it obvious to your visitors who wrote your content? Do your pages carry a byline where a reader would expect one? Does that byline lead anywhere useful? Google's self-assessment questions specifically name author pages and about pages as the places people go looking for background.
None of that is a ranking factor you can tick off. It's a description of how a trustworthy site behaves.
It's also doing double duty now. The same signals that help a reader decide if you're legit help an LLM decide if you're worth quoting. If ChatGPT can't work out who's behind a claim on your site, it's got no good reason to repeat it.
Here's where to start.
1. Tell people who wrote it
Anonymous content is the most common credibility gap I see, and it's almost always accidental. The blog gets set up, the theme doesn't display an author by default, nobody notices and three years of posts go live with nobody attached to them.
The more established your brand, the more likely you are to get away with this, but crediting your authors is best practice.
The fix:
If your content genuinely is a team effort, say so, and name whoever reviewed it for accuracy. A named reviewer beats "our experts" every time.
One thing: if you're going to have bios, keep them current. A bio referencing a job someone left in 2021 is worse than no bio at all.
2. Fix the links that go nowhere
Broken internal links make a site feel neglected. Nothing's wrong with your content, but people start wondering how long it's been like that.
They pile up quietly. A page gets renamed, a service is retired, an old post is deleted and every link pointing at it starts throwing a 404. Your visitors hit a dead end and draw their own conclusions.
To find them:
While you're updating your internal links, have a look at your anchor text. "Click here" and "read more" say nothing. Descriptive anchor text helps your readers and search engines and is one of the levers for fixing keyword cannibalisation.
3. Make it obvious who you are on the homepage
Try this. Ask someone who knows nothing about your business to look at your homepage for five seconds, then close the laptop and tell you what you do.
A lot of homepages fail this. They open with a value proposition so abstract it could belong to a fintech, a hardware store or a yoga studio. "Empowering ambitious teams to unlock what's next" sounds good, says nothing.
What needs to be obvious, fast:
I get the instinct to be aspirational in your hero copy. Just get the specifics on the page too, ideally before anyone has to scroll.
4. Give your about page a job to do
Your about page is visited more often than you’d expect. It’s the first page a journalist, a potential hire or a Google quality rater goes looking for. On most sites it's three sentences about being passionate, generic mission and values, and a photo of the last team offsite.That's a wasted asset.
Give it something to do:
Write it like someone's deciding whether to trust you with a serious budget.
5. Add structured data (less technical than it sounds)
This is the one people skip because it sounds like a developer job.
Structured data (or schema) is a standard way of labelling what's on a page so machines don't have to guess. Google calls it giving "explicit clues about the meaning of a page". You're not adding new information. You're tagging what's there so it can be read properly.
What you want:
FAQ schema is no longer worth adding. Google stopped showing FAQ rich results in May 2026 and dropped support from the Rich Results Test in June, so it won't change how you appear in search.
On WordPress, an SEO plugin like Rank Math or Yoast handles most of your schema through a settings panel. Shopify, Squarespace and Wix output basic structured data by default, with apps for the rest. Google's own documentation points CMS users to plugins rather than editing HTML. If the free version of your plugin only lets you add one schema to a page that needs two, ask Claude Code or ChatGPT to write you the JSON-LD, then add it as an HTML snippet in the page head with something like WPCode.
