Browser extension
The SmileLine Chrome extension puts a free on-page SEO report, link analysis and Google result positions one click away — and, signed in, your practice dialer.
The SmileLine extension for Chrome is a free SEO toolbar. Open it on any page — your own site, a competitor's, a directory listing — and it reads what search engines see. None of the toolbar features needs a SmileLine account, and while you are signed out the extension sends nothing about your browsing to SmileLine.
Signed in with the SEO & Ads add-on, one feature does talk to SmileLine: the domain-metrics overlay on Google results sends the visible result hostnames to your account to look up their authority scores (see Domain metrics). Nothing else about your browsing is sent.
Practices on SmileLine Voice can also sign the extension into their account and take calls straight from the toolbar — see the dialer below.
Install
Open the SmileLine listing on the Chrome Web Store and click Add to Chrome.
Click the puzzle-piece icon in the Chrome toolbar and pin SmileLine so it stays visible.
The on-page report
Open any page and click the SmileLine icon. The popup analyses the page in place:
- Findings — the same checks SmileLine's site audit runs: missing or badly sized titles and meta descriptions, missing or duplicate H1s, missing canonical, pages blocked from indexing, missing local business schema.
- On-page facts — title and meta description lengths, word count, heading structure, canonical URL, meta robots, robots.txt verdict for this page, structured-data types, and hreflang entries.
- Heading outline — every H1–H6 in order, indented by level.
The report reads the page as rendered in your tab. It cannot see the server's HTTP status or response headers, so those checks are left out rather than guessed.
Link analysis
The Links section counts internal, external, nofollow, sponsored and UGC links, and can highlight each kind directly on the page — click a category to outline every matching link, click again to turn it off.
Check internal links probes the page's same-origin links (up to 100) and lists any that return an error, feeding the broken-link finding in the report. External links can't be checked from inside the browser.
Google result positions
On google.com and google.co.uk searches, the extension numbers each organic result so you can read positions at a glance — useful when you're checking where your practice ranks for "dentist in ⟨your town⟩" without counting rows by hand.
Domain metrics (SEO & Ads add-on)
Signed in to a practice with the SEO & Ads add-on, each numbered result also shows the domain's authority metrics — domain rank (0–1000), backlinks, and referring domains — under its title. Lookups come out of your practice's monthly SEO allowance; results are cached for two weeks, so repeat searches are free. Without the add-on (or signed out) the numbering still works and nothing else is shown.
The dialer
With SmileLine Voice enabled for your practice, the extension is also a softphone that stays registered while Chrome is open.
Right-click the SmileLine icon and choose Options (or click Sign in in the popup). Pick your practice region and click Sign in to SmileLine — a SmileLine window asks you to approve the connection for your practice. Anyone whose role can use the dialer may connect.
Click Enable calling (microphone) and allow the microphone when Chrome asks. This is needed once per browser.
Once connected, the popup shows the dialer above the SEO report:
- Incoming calls ring with a Chrome notification — with the patient's name when SmileLine recognises the number — and can be answered or declined from the notification or the popup.
- Outbound calls start from the popup's dial pad, or by selecting a phone number on any web page, right-clicking it and choosing Call with SmileLine.
- In a call you can mute, hold, hang up and send key tones. Closing the popup does not end the call.
- DND pauses ringing on this browser without signing out; calls continue to ring your other SmileLine devices.
Signing out disconnects this browser's calling endpoint entirely — calls stop ringing here until you sign in again.
Calls on your phone
With SmileLine Voice the mobile app is a full practice phone — call leads over the practice line and run Power Dialer sessions from anywhere.
Desk phones
Ring a physical SIP handset directly on one of your numbers — even when SmileLine is unreachable — and understand exactly what that number gives up in return.
