What we check
Missing Open Graph tags mean broken social previews. No favicon looks sloppy. Missing contact info and privacy policies hurt trust with both visitors and search engines. These small details add up and shape how people see your site.
Trust signals tell visitors and search engines that your site is real and run by real people. A missing privacy policy or contact page raises red flags. These are easy to add but easy to forget.
Checks for a favicon link in the page head. Sites without one look unfinished in browser tabs.
Social Sharing Tags (Open Graph)
Verifies og:title and og:description are set. Without them, shared links look broken on social media.
Checks for an og:image meta tag. A good preview image makes shared links stand out.
Verifies the twitter:card meta tag is set. This controls how your link looks when shared on X.
Checks that the page links to other pages on the same site. Internal links help both users and crawlers.
Spots links that return 404 or other errors. Broken links frustrate visitors and waste crawl budget.
Checks for contact info or a link to a contact page. Visitors and search engines both look for this.
Verifies a link to a privacy policy exists. Most ad networks and app stores require one.
Checks for a link to an about page. This builds trust and helps search engines understand your site.
Verifies a link to terms of service. This protects both you and your users.
These 10 checks cover technical health: markup quality and trust indicators. Together, they shape how your site looks when shared and how much people trust it. Run a scan to find gaps and get clear fix steps.
Social sharing tags control what people see when they share your link on social media. Trust indicators like contact info and privacy pages tell both visitors and search engines that your site is legitimate.
What to fix first
- Favicon: Checks for a favicon link in the page head. Sites without one look unfinished in browser tabs.
- Social Sharing Tags (Open Graph): Verifies og:title and og:description are set. Without them, shared links look broken on social media.
- Social Sharing Image: Checks for an og:image meta tag. A good preview image makes shared links stand out.
How to use this audit
- Run the scan and identify which warnings appear across several pages, not just one template.
- Fix the problems that affect visibility, trust, or conversion first, then move on to polish items.
- Re-scan after each batch of changes so you can confirm the issue count actually drops.
Why this matters in the full scan
This category is most useful when you review it alongside the other six. A site can look good in one area and still lose traffic or trust because another area is weak. SiteCurl keeps these checks together so teams can work from one prioritized report instead of juggling separate tools.

Frequently asked questions
What does the technical health check cover?
It checks 10 issues in two areas: markup (favicon, Open Graph, Twitter cards, links) and trust signals (contact info, privacy, about page, terms). Both matter for search and user trust.
Why does SiteCurl check trust signals?
Search engines use trust signals like contact pages and privacy links as quality hints. Visitors also look for these before giving you their time or money.
Does SiteCurl check page speed?
Speed checks are a separate type. The technical health check focuses on markup and trust signals. Run a full audit to see all seven types.
Can I scan more than one page?
The free audit checks your home page. With a paid plan, you can scan up to 100 pages per site and track technical health over time.
What are Open Graph tags?
Open Graph tags control how your link looks when shared on Facebook, LinkedIn, and other social sites. Without them, shared links show a blank preview or wrong text.
Why is a privacy policy important?
Many ad networks and app stores require one. Visitors also expect to see it. Search engines use its presence as a trust signal when ranking your pages.
