Meta Tags Checker
Meta tags are the first thing search engines read on your page. A missing title, a truncated description, a broken canonical — each one costs you rankings or clicks. A meta tags checker validates them all systematically.
What a Meta Tags Checker Validates
A comprehensive meta tags checker validates every SEO-relevant tag in your HTML head: title tags (length, uniqueness, presence), meta descriptions (length, uniqueness), canonical URLs (presence, correct format), robots directives (index/noindex, follow/nofollow), and viewport settings.
Beyond basic presence checks, a good checker validates correctness: is the title under 60 characters? Is the description between 120 and 160 characters? Does the canonical URL match the page URL? Are there conflicting robots directives between meta tags and HTTP headers?
Indxel checks all of these in a single npx indxel check command. It crawls your site, extracts meta tags from every page, validates against 15+ rules, and reports issues with the specific page URL and the failing value.
Common Meta Tag Mistakes
The most common mistake is missing meta descriptions on inner pages. Developers set up the homepage metadata carefully but forget category pages, blog posts, or dynamically generated routes. Each missing description is a missed opportunity to control your SERP snippet.
Duplicate titles across pages confuse search engines about which page to rank for a query. This happens when a layout sets a static title and pages do not override it, or when a template generates pages with identical titles.
Broken canonical URLs — pointing to non-existent pages, using relative URLs instead of absolute, or having multiple canonical tags on one page — send conflicting signals to Google. The wrong URL may get indexed while the right one gets ignored.
Browser Extensions vs CLI Tools
Browser extensions like SEO Meta in 1 Click or META SEO Inspector show meta tags for the current page. They are useful for spot-checking individual pages, but they cannot validate an entire site at once.
CLI tools like Indxel crawl your entire site and check every page against the same rules. This scales from 10 pages to 10,000 pages. The output is machine-readable, so it integrates with CI/CD pipelines and automated workflows.
The tradeoff is immediate visual feedback (extensions) versus systematic coverage (CLI). For development, use both: the extension for quick checks during development, the CLI for comprehensive validation before deploy.
Automating Meta Tag Validation
Manual checking does not scale. Every new page, every content update, every code refactor can introduce meta tag issues. Automation ensures every deploy meets your SEO standards.
Add npx indxel check --ci to your build command. It runs the full meta tag validation suite and exits with a non-zero code if critical issues are found. This blocks the deploy, just like a failing test suite. No broken meta tags reach production.
For continuous monitoring, schedule regular crawls that compare current meta tags against previous baselines. Any changes — intentional or accidental — get flagged for review. This catches CMS-driven changes, A/B testing side effects, and package updates that break metadata generation.
Frequently asked questions
How many meta tags should a page have?
At minimum: title, meta description, canonical URL, viewport, and og:title/og:description/og:image. Optional but recommended: twitter:card, robots directive, and hreflang for multi-language sites.
Can meta tags hurt SEO?
Yes. An accidental noindex tag removes a page from Google entirely. A canonical pointing to the wrong URL consolidates ranking signals to the wrong page. Duplicate titles and descriptions dilute ranking signals across pages.
Does Indxel check meta tags on live sites or local builds?
Both. npx indxel check crawls a live URL or localhost. Use it locally during development, in CI against a preview deployment, or against your production site for ongoing monitoring.

Meta Description Checker
Meta descriptions appear as the snippet in search results. Too long and they get truncated. Too short and they waste SERP real estate. Missing entirely and Google writes its own. A checker catches all three problems.
OG Tags Checker
When someone shares your link on Twitter, LinkedIn, or Slack, Open Graph tags control the preview card. Broken OG tags mean broken previews — no image, wrong title, or a generic fallback. An OG tags checker catches these before your content goes viral with a broken card.
Next.js SEO Meta Tags
Meta tags are the foundation of on-page SEO. Next.js App Router replaces the old Head component with a typed metadata API that merges across layouts and pages. Here is how to use it correctly.
