Eight practical SEO checks to run before publishing
Fix the technical signals that most often split relevance: international URLs, search listings, canonicals, and the links that move readers to the next page.
International SEO Audit
Paste one localized page's rendered HTML and check its language, hreflang, canonical, and fallback signals before international pages split their relevance across regions.
Open toolHreflang Generator
Paste your language/region URLs and get valid hreflang tags back, link elements for the <head>, plus an hreflang sitemap, with the x-default and return links Google requires.
Open toolSearch Listing Preview
See exactly how your page will appear as a Google search listing, an X card, and a Facebook or LinkedIn share, with pixel-width warnings before your title gets truncated.
Open toolCanonical URL Checker
Paste a page's HTML to check its canonical link, or enter a URL to generate a canonical tag in your browser. Find missing, duplicate, relative, or conflicting canonical URLs before they confuse search engines.
Open toolSEO Title Checker
Check an SEO title tag or headline before you publish: score length, keyword placement, clarity, and click potential, with fixes you can apply straight away.
Open toolKeyword Clustering Tool
Use a free keyword clustering tool and keyword grouping software to group related SEO keywords before assigning pages, briefs, or articles to them.
Open toolInternal Linking Tool
Paste a source-page topic and a small page inventory to get explainable internal-link suggestions with matched terms, anchors, and ready-to-review HTML.
Open toolSEO Report Template
Generate a practical SEO report template for client reviews: equal comparison windows, Search Console metrics, page and query movement, evidence, owners, and next actions.
Open toolSEO Roadmap Template
Generate a practical 90-day SEO roadmap that turns Search Console evidence, technical checks, content revisions, and conversion goals into an owned weekly plan.
Open toolContent Strategy
HTML to Markdown
Paste HTML and get clean Markdown — headings, links, lists, code blocks and GitHub-flavoured tables preserved. Nothing is fetched and nothing is stored.
AI Visibility Checker
Use a free AI visibility checker to see whether Perplexity or ChatGPT cites your site for a buyer question, compare repeat checks over time, and see which sites they cite instead.
LLM SEO Checker
Use an LLM SEO checker and analysis tool to audit a draft for direct answers, useful evidence, clear structure, examples, and readable length before publishing. The browser check does not claim to predict rankings.
SEO Content Brief Generator
Create an AI-assisted SEO content brief with search intent, angle, headings, questions, and optimization notes. Hand the output straight to a writer, freelance or in-house, so briefing takes minutes instead of a back-and-forth call.
Outline Generator
Build an SEO-friendly outline with sections, key points, examples, and FAQs. Give it a topic and get back an H2 structure a writer can follow directly, instead of starting outline-planning from scratch.
Content Idea Generator
Generate blog, social, newsletter, and product-led content ideas from one topic. Useful when a content calendar runs dry, it surfaces angles across formats instead of just more blog-post titles.
SEO Article Generator
Use a free SEO article generator to create an AI-assisted draft with a headline, intro, sections, conclusion, and FAQs. Edit and expand it before publishing; use it to clear a blank page or test an angle before committing writer time.
SEO Roadmap Template
Generate a practical 90-day SEO roadmap that turns Search Console evidence, technical checks, content revisions, and conversion goals into an owned weekly plan.
SEO Report Template
Generate a practical SEO report template for client reviews: equal comparison windows, Search Console metrics, page and query movement, evidence, owners, and next actions.
Internal Linking Tool
Paste a source-page topic and a small page inventory to get explainable internal-link suggestions with matched terms, anchors, and ready-to-review HTML.
Conversion
AI CTA Generator
Create short call-to-action options for landing pages, ads, emails, and product prompts.
Headline Generator
Create punchy on-page headline ideas for blog posts, ads, newsletters, and social campaigns, not the search-result title tag. Generate a batch of options and test the strongest ones instead of publishing your first draft headline.
Keyword Research
LSI Keyword Tool
Generate semantically related keywords, entities, modifiers, and question patterns for any seed term, so a page covers the topic the way search engines expect. Feed the output into an outline or brief so a page reads as comprehensive to readers and search engines alike, not just keyword-matched.
Keyword Density Analyzer
Analyze how often a keyword appears in text and compare it with top repeated terms. Use it as a sanity check before publishing, to confirm a target keyword shows up often enough without tipping into keyword stuffing.
Keyword Clustering Tool
Use a free keyword clustering tool and keyword grouping software to group related SEO keywords before assigning pages, briefs, or articles to them.
Low-Hanging Fruit Finder
Paste a Google Search Console query export and find keywords that already earn impressions but need a focused refresh to move closer to page one.
Keyword Combiner
Paste two or three keyword lists and get every combination back, the fast way to build a long-tail keyword set or a paid-search keyword matrix without doing it by hand in a spreadsheet.
SERP Optimization
SEO Title Generator
Generate SEO title tags for search results, with keyword relevance, clear promises, and click-through appeal. Also called SEO headlines, these are the titles searchers click before they reach your page.
Meta Description Generator
Write concise meta descriptions that summarize the page and invite searchers to click. Generate a few angles for the same page and pick the one most likely to earn the click in a crowded results page.
SEO Title Checker
Check an SEO title tag or headline before you publish: score length, keyword placement, clarity, and click potential, with fixes you can apply straight away.
Search Listing Preview
See exactly how your page will appear as a Google search listing, an X card, and a Facebook or LinkedIn share, with pixel-width warnings before your title gets truncated.
Etsy Title Generator
Build an Etsy listing title that uses all 140 characters well, primary keyword first, long-tail phrases after, no repetition, plus the 13 tags to match.
Technical SEO
Image Extractor
Enter a page URL and get every image it references — img tags, responsive srcset variants and the Open Graph image — as a plain list of direct links.
Favicon Downloader
Enter a site and get every icon it declares — favicon, apple-touch-icon, mask-icon and each declared size — as direct links you can open or save.
Canonical URL Checker
Paste a page's HTML to check its canonical link, or enter a URL to generate a canonical tag in your browser. Find missing, duplicate, relative, or conflicting canonical URLs before they confuse search engines.
Slug Generator
Turn any title into a clean, lowercase, hyphenated URL slug, stop words stripped, length checked, ready to paste into WordPress, Webflow, or whatever runs your site.
Robots.txt Generator
Generate a robots.txt file with crawl rules, sitemap location, and optional blocked paths.
Snippet Generator
Create JSON-LD schema snippets for articles, FAQs, products, and local business pages.
SEO Checker
Run an instant on-page SEO check: title length, meta description length, keyword presence, and heading structure, no crawler, no signup.
UTM Builder
Build a UTM-tagged URL for campaign tracking, source, medium, campaign, term, and content, all in one clean link. Keeps tagging consistent across a team, so campaign reporting in analytics doesn't fragment into near-duplicate source/medium combinations.
SEO Audit Template
Generate a practical SEO audit template and technical SEO checklist for crawlability, indexation, canonical URLs, page delivery, structured data, and measurement. Copy the worksheet into an audit report and 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
Paste one localized page's rendered HTML and check its language, hreflang, canonical, and fallback signals before international pages split their relevance across regions.
Googlebot Simulator
Paste rendered HTML and inspect the title, robots directive, canonical, headings, links, and visible text a crawler can receive without pretending to fetch or render the live page.
Hreflang Generator
Paste your language/region URLs and get valid hreflang tags back, link elements for the <head>, plus an hreflang sitemap, with the x-default and return links Google requires.
Shopify SEO Audit
Paste rendered Shopify HTML and check the technical signals that affect product and collection visibility: indexability, canonicals, metadata, headings, product schema, and Open Graph tags.
Product Listing Schema Generator
Generate valid Product, FAQPage, or Review JSON-LD for visible offers, questions, ratings, and answers, with additional formats for organizations, local businesses, articles, and breadcrumbs.
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.
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.
