Which tool for each task

Pick the job you need to finish first. Each card lists trade-offs and links straight to the Utilnivo tool—free, no account required unless a tool page notes temporary server processing.

Draft title and meta description tags

Use Meta Tag Generator or Meta Tag Preview.

Pros

  • Produces starter title, description, and social tags from your copy.
  • Pairs with preview tools before deploy.
  • No account required.

Cons

  • Each important URL needs unique tags—one block is not enough for a whole site.
  • Google may rewrite titles in search results.

When to choose this: Generate tags for homepage, blog template, and landing pages before launch.

Open Meta Tag Generator

Preview search and social snippets

Use SERP Snippet Preview or Meta Tag Preview, Open Graph Preview.

Pros

  • SERP Snippet Preview approximates Google title/description length.
  • Open Graph Preview checks share-card image and text.
  • Catch truncation before publishing campaigns.

Cons

  • Platforms crop differently—verify live URLs after deploy.
  • Previews use text you paste, not cached crawler data.

When to choose this: Run previews after Meta Tag Generator and before sharing marketing links.

Create and validate XML sitemaps

Use Sitemap Generator or Sitemap Validator.

Pros

  • Builds sitemap XML from URL lists you supply.
  • Validator catches syntax errors before Search Console upload.
  • Speeds up static-site launches.

Cons

  • You must keep URLs current when pages are added or removed.
  • Very large sites may need index sitemaps or CMS automation.

When to choose this: Use when launching a hand-coded or small business site without a CMS sitemap.

Write and test robots.txt

Use Robots.txt Generator or Robots.txt Tester.

Pros

  • Drafts allow/disallow rules and sitemap references.
  • Tester checks live robots.txt responses.
  • Catches typos that block entire sites.

Cons

  • Robots.txt is not access control—use auth for private areas.
  • Blocking CSS or JS can hurt rendering.

When to choose this: Generate robots.txt on day one of launch, then test after DNS goes live.

Open Robots.txt Generator

Find broken links before launch

Use Broken Link Checker or Link Extractor, HTTP Status Checker.

Pros

  • Scans anchors in HTML you provide for 404 and error responses.
  • Link Extractor lists outbound URLs to audit in batches.
  • HTTP Status Checker validates important paths quickly.

Cons

  • Does not crawl your entire domain automatically—you supply pages or HTML.
  • Some partner URLs block bots with 403.

When to choose this: Run on homepage, blog template, and footer-heavy pages after migrations.

Open Broken Link Checker

Inspect HTTP headers and redirects

Use HTTP Header Checker or Redirect Checker, Canonical Tag Checker.

Pros

  • Confirms HTTPS, cache, and status codes on live URLs.
  • Redirect Checker counts hops on chained URLs.
  • Canonical Tag Checker flags missing or duplicate canonicals.

Cons

  • Live fetches may differ from localhost staging.
  • CDN caching can mask recent header changes briefly.

When to choose this: Use after deploy when Search Console shows redirect or indexing issues.

Open HTTP Header Checker

Validate structured data (JSON-LD)

Use Schema Validator or Schema Markup Generator.

Pros

  • Syntax-checks JSON-LD before you ship rich results.
  • Generator drafts common schema types to paste into pages.
  • Reduces Search Console structured-data errors.

Cons

  • Valid syntax does not guarantee rich-result eligibility.
  • Match schema type to visible on-page content.

When to choose this: Validate every template that uses FAQ, Product, or Organization schema.

Open Schema Validator

Build trackable campaign URLs

Use UTM Builder or URL Slug Generator.

Pros

  • Adds consistent UTM parameters for analytics reporting.
  • URL Slug Generator helps readable paths for new landing pages.
  • Pairs with QR Code Generator for print campaigns.

Cons

  • UTMs do not replace good on-page SEO.
  • Inconsistent naming breaks campaign reports.

When to choose this: Create UTMs before newsletter, ad, or social launches—keep a naming spreadsheet.

Open UTM Builder

Overview

The best free SEO tools depend on whether you are launching a site, fixing crawl errors, or prepping a campaign link. This search-intent guide compares Utilnivo’s SEO utilities task by task instead of dumping a directory list.

Generators and previews run on text you enter locally. URL checkers fetch live pages—do not test private admin URLs. These tools complement Google Search Console; they do not replace it.

Follow the SEO launch checklist workflow for the core pre-launch order: headers, meta tags, robots.txt, and sitemap.

How to choose

  • Draft tags → Meta Tag Generator.
  • Snippet preview → SERP Snippet Preview.
  • Sitemap → Sitemap Generator.
  • Crawl rules → Robots.txt Generator.
  • Broken links → Broken Link Checker.
  • Headers and redirects → HTTP Header Checker.
  • JSON-LD → Schema Validator.
  • Campaign URL → UTM Builder.

Frequently asked questions

Do these tools crawl my whole site?

Most check URLs or HTML you supply. Start with key templates, then expand.

Will previews match Google exactly?

No. They use common length heuristics; Google may rewrite titles.

Are live URL checks server-side?

Yes for fetch-based checkers. Read each tool page before testing staging credentials.
