Questions about the tools, answered.
Everything people ask about the audit, meta tags, sitemaps, robots.txt, and the rest — grouped by tool so you can jump straight to what you are using.
SEO Audit Report
Open the tool →What does the audit actually check?
It fetches your page and checks the title, meta description, headings, image alt text, canonical and robots tags, mobile viewport, language attribute, HTTPS, Open Graph and Twitter tags, JSON-LD structured data, word count, links, and page weight. Each finding comes with a plain-English recommendation.
What is a good audit score?
The score runs from 0 to 100. Above 90 means the basics are solid. Between 70 and 90 there are a few warnings worth fixing. Below 70 means real issues are hurting your visibility — start with the failing checks at the top of the report.
Why does the audit say it cannot reach my page?
Some sites block automated requests or require JavaScript to render. Make sure the URL starts with https://, loads in a private browser window, and is not behind a login. Pages that render entirely in JavaScript may report missing tags even when they exist.
Can I save the report?
Yes. Use the copy or download buttons on the report to get a Markdown file with every finding and recommendation, so you can attach it to a ticket or share it with a developer.
Meta Tag Generator
Open the tool →How long should my title and description be?
Keep titles around 50–60 characters and descriptions around 150–160 characters. The live counters warn you as you approach the limits where Google starts truncating.
Where do I paste the generated tags?
Copy the HTML output and paste it inside the <head> section of your page, before the closing </head> tag. Most website builders and CMSs have a dedicated SEO or head-code field for this.
Do I need Open Graph and Twitter tags too?
Yes if you share links on social media. Without them, platforms guess a title and image, often badly. The generator produces them from the same fields, so it costs you nothing extra.
SERP Snippet Preview
Open the tool →Does Google always show my title and description exactly?
No. Google rewrites snippets when it thinks another part of your page matches the search better. A clear, relevant title and description makes rewrites far less likely.
Why check both desktop and mobile?
Mobile results truncate sooner and show the URL differently. A title that fits on desktop can get cut on a phone, so preview both before publishing.
Open Graph Preview
Open the tool →What image size should I use for og:image?
1200×630 pixels is the widely supported standard. Use an absolute https URL — relative paths are ignored by most platforms.
I updated my tags but Facebook still shows the old card. Why?
Social platforms cache share cards aggressively. Paste your URL into the platform's sharing debugger to force a re-scrape after updating tags.
Schema Markup (JSON-LD)
Open the tool →What is schema markup and do I need it?
Schema markup is structured data that tells search engines exactly what your page is — an article, product, FAQ, local business, or breadcrumb trail. It can unlock rich results like star ratings, FAQ dropdowns, and breadcrumbs in search.
Where do I put the JSON-LD code?
Paste the generated <script type="application/ld+json"> block anywhere in your page's HTML — the <head> is the convention. Then test the URL in Google's Rich Results Test.
Does schema markup guarantee rich results?
No. Google decides whether to show rich results per query. Valid, accurate markup makes you eligible — inaccurate or spammy markup can get it ignored entirely.
XML Sitemap Generator
Open the tool →Where do I put the sitemap file?
Save the output as sitemap.xml in your site's root so it is reachable at yourdomain.com/sitemap.xml. Then reference it in robots.txt and submit it in Google Search Console.
What should I use for lastmod, changefreq, and priority?
lastmod is the date the page last changed. changefreq is a hint (weekly for most pages). priority ranges from 0.0 to 1.0 — give your homepage 1.0 and ordinary pages 0.5–0.8.
How many URLs can a sitemap have?
Up to 50,000 URLs or 50 MB per file. Most small sites fit comfortably in one sitemap.
Robots.txt Generator
Open the tool →Does robots.txt keep pages out of Google?
It stops crawling, not indexing. A blocked page can still appear in search without a description if other sites link to it. To truly keep a page out of search, use a noindex meta tag instead.
Should I block AI crawlers?
That is your call. The generator includes presets for common AI bots (GPTBot, ClaudeBot, and others) so you can block training crawlers without blocking search engines.
Where does robots.txt go?
In the site root at yourdomain.com/robots.txt. There is exactly one per domain.
Robots.txt Tester
Open the tool →What does the tester do?
It fetches your live robots.txt, parses every rule, and tells you whether Googlebot (or another crawler) is allowed to fetch a specific URL. It also extracts and validates your sitemap references.
Why does my robots.txt show rules I never wrote?
Many hosts and CMSs generate a default robots.txt. Test the live file before assuming yours is the one being served — and after any CDN or hosting change.
Hreflang Tag Generator
Open the tool →When do I need hreflang tags?
When the same content exists in multiple languages or regional versions — for example English for the US and UK, or a site in English and French. They tell Google which version to show each visitor.
What is x-default?
The fallback page shown to visitors whose language does not match any of your versions — usually your main international page. Every hreflang set should include one.
Keyword Density Analyzer
Open the tool →What keyword density should I aim for?
There is no magic number. If your main phrase reads naturally and appears a handful of times, you are fine. Density far above 2–3% usually reads as stuffing and can hurt rankings.
Why filter out stopwords?
Words like "the", "and", and "of" dominate every text and drown out the phrases that matter. The stopword filter removes them so you see your real keyword usage.
Readability Analyzer
Open the tool →What is a good Flesch Reading Ease score?
60–70 is the sweet spot for general web content — plain English a 13–15-year-old can read. Below 50 gets hard work; short sentences and common words are the fastest fix.
Does readability affect SEO?
Indirectly. Easier text keeps visitors on the page longer and helps them finish what they came to do, which correlates with better engagement signals.
UTM Campaign URL Builder
Open the tool →What are UTM parameters for?
They tag a link so your analytics knows exactly which campaign, source (newsletter, Twitter, ad), and medium (email, social, cpc) brought each visitor.
Why lowercase everything?
UTM values are case-sensitive in analytics tools — "Newsletter" and "newsletter" show up as two separate sources. Lowercase keeps your reports clean. The builder does this automatically.
