Built a free Chrome extension that shows you how a page will actually look when it's shared on Facebook, LinkedIn, or X - the meta tags and the real preview card, in one click, no separate site, no waiting on a scan.

Click the icon, it reads the page you're on, nothing else, nothing stored, no account needed.

Free if it's useful to you too:

Backlinks are the internet's version of 'word of mouth'.

Every real site that links to yours is telling Google "this one's legit." Ten solid recommendations from respected neighbors beat a thousand from strangers nobody trusts - which is why buying 5,000 spam links does the opposite of what the guy selling them promised. Link-spam isn’t helpful.

It's the least visible part of SEO and one of the most decisive. Nobody sees your backlink profile. Google sees nothing else quite as clearly.

Slow, boring, compounding…. Like most things that work.

A page is not a website.

I know it feels like one. It's got your hours, your photos, your reviews, people can message you (hopefully!). For a lot of businesses it's the only thing they've got.

Here's the problem. You don't own any of it.

You don't own the URL. You don't own the audience. You can't install tracking, you can't control how it shows up in search, and you can't do a thing when the algorithm decides your posts reach 4% (if you're lucky) of your followers instead of 40%.

And when someone searches for what you actually do, Google isn't handing them your page. It's handing them whoever has a real site.

Google shut down the free Business Profile websites in 2024 and took millions of them offline overnight. Everyone using one as their website found out the hard way that renting isn't owning.

Facebook's a great place to be found. It's a bad place to live.

Kept opening a separate site every time I needed to check a page's schema markup, so I finally built myself a Chrome extension that does it in one click instead.

It's called Schema Inspector. Click the icon, it shows you the structured data already on the page - what Google (and now AI search) actually sees when it looks at your site. Free, no account needed, and it only reads the page you're currently on.

Made it public in case it's useful to anyone else who works on websites:

I homebrew and sideload a lot of small utility Chrome extensions for myself, made this one public. Schema Inspector. Simple, does one job.

See the schema.org structured data (JSON-LD and microdata) on any page in one click. Free tool from Yellowfin Development available in the Google Chrome Web Store.

Most schema checkers make you copy a URL into a separate site, wait for it to load, then dig through a wall of results to find out what is actually on the page.

Schema Inspector skips that step. Click the icon and it reads the JSON-LD and microdata already sitting in the page you are looking at: what entities are declared, what type each one is, and whether the JSON is even valid. Grouped, readable, and copyable in one click.

It's not a new idea, there are already a few of these. But look at what most of them ask for when you install: full access to every site you visit, all the time. I didn't love that for a tool I'd be running constantly, so I built mine differently.

Mine only asks for "activeTab." It sees the page you're on, only for the second you click the icon. No standing access. Nothing running in the background. Nothing leaves your browser.

Built for anyone who works with SEO or web development day to day - checking your own markup before it ships, auditing a client's site, or just curious what a page is telling Google about itself.

Everything happens locally in your browser. Nothing is collected, stored, or sent anywhere.

If there's something you'd want it to do that it doesn't yet, tell me. Might build it.

"Can you look at this and tell me if it's any good?"

A client asked me to review a competitor's ad proposal. The top-performing line in the report turned out to be their own brand name - people who already knew the company - boxed out with a white block so it wouldn't stand out.

I ran the numbers with the brand campaign pulled back out. The real cost per conversion was 45% higher than what the report showed.

Here's the full breakdown, and the one question worth asking whoever runs your ads:

Somebody sold you SEO. The reports look busy. The phone still isn't ringing.

Here's a thing most people never get told: the four types of SEO aren't equal, and doing them in the wrong order is how budgets disappear.

We scanned 230 small business sites last month. 70% had at least one technical problem - the kind where you could write a hundred perfect pages and nobody would ever see them.

Fix the foundation first. Then the listings. Then the content. Links last.

Full guide with a cost and timeline table for each:
