Small business guide
What this tool helps you do
Use this free website SEO checker to audit any page's technical foundations in about ten seconds: title and meta description, mobile viewport, headings, image alt coverage, canonical and robots directives, Open Graph and Twitter tags, structured data, robots.txt, sitemap, HTTPS, response time, and content depth — each reported as pass, warn, or fail with a plain-language fix.
Two honest notes before you run it. First, every check here is deterministic — real rules checked against your real HTML, not an AI's opinion of your website. Second, a single-page HTML audit has limits, and the tool tells you what they are (it can't render JavaScript, measure Core Web Vitals in real browsers, or crawl your whole site). What it can do is catch the basics that quietly sabotage small business sites — a noindex left on after launch, a missing title, no mobile viewport — and those basics are the correct first hour of SEO work.
How to use this tool
- 1
Enter your page URL — the homepage is a good start, but check your key service and product pages too.
- 2
Read the score, then jump to the red fails: those are the items actively costing you.
- 3
Work through the yellow warnings next — each comes with the specific fix.
- 4
Re-run after fixing to confirm the score moves; repeat for your most important pages.
- 5
Read "what this check can't see" and set up Google Search Console for the parts beyond any instant checker.
Examples
The invisible services page
A plumber's services page gets no search traffic despite good reviews.
Inputs
- URL: reyesplumbing.com/services
Result
Score 41/100. Fails: meta robots contains noindex (left over from the site rebuild), no meta description, no H1. Warnings: title is 78 characters, no sitemap.xml.
The noindex alone explains the missing traffic — the page was politely asking Google not to list it. That's the kind of invisible, catastrophic detail an audit surfaces in seconds and no amount of content writing would have fixed.
A decent site with sharable gaps
A bakery checks its homepage before a local press mention.
Inputs
- URL: hobokenbread.com
Result
Score 82/100. Passes across meta, headings, HTTPS, robots. Warnings: missing og:image (shares show no photo), 2 of 9 images weak on alt text, no structured data.
Nothing was broken, but the og:image gap mattered that week — a news article's link to the bakery would have rendered without a photo. Five minutes with the Meta Tags Generator fixed it before the story ran.
Key terms
Technical SEO
The plumbing under your content: tags, directives, and files that determine whether search engines can find, read, and correctly display your pages. Content decides how well you rank; technical SEO decides whether you're in the race.
noindex
A meta robots value that tells search engines to leave the page out of results. Useful on purpose (thank-you pages), devastating by accident — it's checked first for a reason.
Canonical URL
The tag declaring a page's one official address, so duplicates (www vs non-www, tracking parameters) don't split your ranking signals.
Structured data (JSON-LD)
Machine-readable facts about your page — business type, FAQs, products — that make you eligible for richer search listings. The checker reports which types it found and whether they parse.
How to interpret the result
Fails first, then warnings, then move on
The score weights every check equally-ish, but your attention shouldn't: a noindex or a missing title is worth more than every warning combined. Clear the fails today, schedule the warnings, and don't chase 100 — a 90+ page with strong content beats a technically perfect page with thin content every time.
An instant audit is a floor, not a ceiling
This checker reads one page's HTML, once, the way a crawler's first pass does. It cannot see how fast the page feels on a phone (Core Web Vitals), content that JavaScript builds after load, sitewide crawl issues, or backlinks. That's why the results panel names its blind spots and points to Google Search Console and PageSpeed Insights — free tools that cover exactly those. Passing here means the foundations are right; it doesn't mean the work is finished.
Common mistakes
- Auditing only the homepage — service and product pages earn the money and hide the worst issues.
- Fixing the score instead of the business: obsessing over an info-level item while a fail sits unaddressed.
- Leaving launch-day settings live: noindex from the staging site is the classic silent killer.
- Running the check once and never again — every redesign, plugin, and "quick edit" can regress the basics.
- Treating a good technical score as an SEO strategy; it's the prerequisite, not the plan. Content targeting real searches is the plan.
Frequently asked questions
Is this website SEO checker really free?+
Yes — free, no signup, no report emailed to you (it's on your screen), nothing stored. We fetch the page once, run the checks, and discard everything.
How is the score calculated?+
Deterministically: each check passes (1 point), warns (half), or fails (0), and the score is the percentage across all scored checks. Info-level items don't count. Same page, same result — no AI judgment involved, so you can re-run after a fix and trust the delta.
Why does my page score differently from other SEO tools?+
Every tool checks a different list with different weights, and many blend in estimated metrics or AI commentary. Ignore cross-tool comparisons; use any one tool consistently and watch your own trend. Ours tells you exactly which checks moved.
Can it check my whole website?+
No — one page per run, by design. Check your handful of money pages individually; if all of them share an issue (missing descriptions, weak alts), it's almost always a template fix that resolves the whole site at once.
What about page speed and Core Web Vitals?+
We report server response time and HTML size — real but partial speed signals. Full Core Web Vitals need real-browser measurement: use PageSpeed Insights (free) for that, and treat its field data as the truth. The results panel links the gap honestly rather than guessing.
My site is built with Wix/Squarespace/Shopify — can I fix these issues?+
Almost all of them, yes. Titles, descriptions, alt text, and social images are editable in every major builder's page settings; canonical tags and sitemaps are usually automatic. If a fail points at something your builder controls (like HTTPS), it's typically a one-toggle or support-ticket fix.
