Technical SEO Checklist
Use a practical technical SEO checklist for 2026 and printable audit template for crawlability, indexation, canonical URLs, page delivery, structured data, and measurement. Attach evidence to every check.
SEO Audit Tool
Get a narrative SEO audit for a page: strengths, gaps, and prioritized fixes based on the URL, target keyword, and context you provide. A deeper, written review, not the instant pass/fail checks from the SEO Checker. Best used early in a project, before an outline is written, so structural or on-page gaps are cheaper to fix now than after publishing.
Broken Link Checker
Paste a list of URLs and check which ones are dead. Each link is checked live for its HTTP status so you can find and fix 404s before they cost you traffic or trust. Run it before a big content push or after a site migration, when stale outbound links are most likely to have crept in.
Google Search Console Backlink Checker
Paste a Google Search Console Links export and summarize linking domains, target pages, anchor text, and reported link counts in your browser. No live crawl or backlink-index subscription is required.
International SEO Audit

Anchor Text Generator
Build a natural anchor text mix for internal links and outreach, exact match, partial, branded, and long-tail variants in the ratio that looks earned rather than built.
Alt Text Generator
Turn a messy image filename into clean, accessible alt text, and get told when your alt text is too long, redundant, keyword-stuffed, or should be empty entirely.
llms.txt Generator
Paste your site's pages, one per line, and generate a properly formatted llms.txt file — the emerging standard that tells AI crawlers and LLMs which pages on your site matter and what they're about.
GBP Audit Tool
Answer a few questions about your Google Business Profile (formerly Google My Business) and get a scored checklist of what's missing, weak, or worth fixing before your next local-search push.
Meta Tag Checker
Paste rendered page HTML to check title tag, meta description, meta robots, and canonical tag length and content before you publish, or while auditing an existing page.
Duplicate Content Checker
Paste two blocks of text to see a similarity score and exactly which sentences overlap, so you can tell whether a rewrite is different enough or still reads as duplicate content to Google.
Indexability Checker
Paste rendered page HTML (and robots.txt, if you have it) to check whether Google is technically allowed to index the page — noindex tags, canonical mismatches, and robots.txt blocks, all in one pass.
Writing
Article Summarizer
Condense long text into a short summary, key takeaways, and suggested headline. Paste in a long article, report, or transcript and get the gist back in seconds, handy for skimming research before you write, or turning a long post into a shareable recap.
Passive Voice Checker
Scan a draft for passive-voice sentences so you can tighten the writing before you publish. Especially useful for content headed for search, active-voice writing tends to read clearer and hold attention longer.
