Getting Started

Choose A Question, Then Choose A Tool

Start in the Toolbox, select the tool that matches the question you need to answer, and provide only the input that tool requests. Depending on the tool, the input may be a domain such as example.com, a complete public URL such as https://example.com/page, an IP address such as 192.0.2.10, a keyword, text, code, DNS details, or a supported CSV sample. These are illustrative examples, not live measurements.

  1. Open the tool from the directory below or from the Toolbox.
  2. Read the format note above its form. Do not add a URL scheme to a domain-only field, and do not paste unrelated material into a text field.
  3. Submit the form and wait for the result or an explicit validation message.
  4. Check the timestamp, source, signal, and limitation notes before acting.
  5. Make changes only after confirming them against your own website or authoritative provider, then rerun the relevant check.

Never submit passwords, API secrets, session cookies, private customer information, confidential URLs, or any data the selected feature does not explicitly and securely require.

SEO Audit

Website SEO Audit

Review the public page title, descriptions, headings, links, images, indexability signals, and response metadata.

What It Checks: On-page SEO signals for one submitted website page. This specific tool: Review the public page title, descriptions, headings, links, images, indexability signals, and response metadata.

When To Use It: Use this tool when the question described above matches the issue you are investigating. If you need a different measurement, choose a related tool below rather than treating this result as a substitute.

Input: Use a complete HTTP or HTTPS address, for example https://example.com/page. The server rejects unsafe destinations and may reject sites that cannot be reached.

Access: This tool is public by default. A browser session can run three free tool tests before registration is requested; administrators can change access settings.

How To Use It

  1. Open Website SEO Audit.
  2. Enter the requested public website url in the form. Use only the fields shown by the tool.
  3. Submit the form. If it rejects the input, follow the message and correct the format before retrying.
  4. Review the returned values, findings, warnings, and source notes. Compare them with the real page, file, or DNS zone.

Illustrative Example: https://example.com/. This demonstrates input formatting only; it is not a live result or a claim about any website.

Understanding Results: A pass applies only to the specific signal checked. A warning is a prompt to verify context, not proof of harm; an error can indicate a retrieval or input problem rather than a defect in the target site.

Common Next Step: If the URL is rejected or times out, confirm its scheme, spelling, public availability, and redirect destination. Recheck from a browser before changing server or indexing settings.

Limitations: The audit is limited to the submitted public page and checks supported by the current release; it is not a complete site crawl. A result is an observation or local computation, not a guarantee of indexing, ranking, security, business performance, or legal compliance.

Understanding Results: The output describes the submitted text or code. It does not establish search demand, audience response, or production behavior unless the tool explicitly performs that check.

Common Next Step: If input validation fails, remove unrelated text and follow the form's stated format. If the output is incomplete, reduce the sample and retry; do not infer missing measurements.

Limitations: The timing reflects a server-side request from this application, not the full visual experience or user-perceived performance in every browser and location. A result is an observation or local computation, not a guarantee of indexing, ranking, security, business performance, or legal compliance.

Common Next Step: If the URL is rejected or times out, confirm its scheme, spelling, public availability, and redirect destination. Recheck from a browser before changing server or indexing settings.

Limitations: This tool evaluates only the public website url and data source described on its page. It does not replace a full-site review, an authoritative source check, or professional judgment for high-impact changes. A result is an observation or local computation, not a guarantee of indexing, ranking, security, business performance, or legal compliance.

What It Checks: A targeted validation of the selected input or public page, not a complete certification. This specific tool: Check domain age checker using the data and technical sources available to this deployment.

When To Use It: Use this tool when the question described above matches the issue you are investigating. If you need a different measurement, choose a related tool below rather than treating this result as a substitute.

Input: Enter a hostname without a path, such as example.com. Do not enter a URL scheme unless the tool specifically requests one.

Access: This tool is public by default. A browser session can run three free tool tests before registration is requested; administrators can change access settings.

How To Use It

  1. Open Domain Age Checker.
  2. Enter the requested domain name in the form. Use only the fields shown by the tool.
  3. Submit the form. If it rejects the input, follow the message and correct the format before retrying.
  4. Review the returned values, findings, warnings, and source notes. Compare them with the real page, file, or DNS zone.

Illustrative Example: example.com. This demonstrates input formatting only; it is not a live result or a claim about any website.

Understanding Results: Treat returned records and timestamps as a snapshot from the named source or resolver. An absent field can mean unavailable data; it is not proof that a record or service does not exist.

Common Next Step: If no answer appears, confirm the exact hostname and record type, then compare with the authoritative zone or registrar. DNS caches and registry coverage can differ.

Limitations: Domain age is derived from public RDAP registration events when available. Registries may omit, redact, or format dates differently. A result is an observation or local computation, not a guarantee of indexing, ranking, security, business performance, or legal compliance.

Interpretation

Understanding Results, Scores, Warnings, And Errors

A result applies to the individual signal the tool checked. “Pass” means that signal met the tool's stated condition at the time of the request; it does not certify the full website. “Warning” means that context or a possible issue deserves review. “Error” can mean invalid input, a blocked or unavailable destination, an external provider failure, or a failed check. Read the explanation and source information before drawing a conclusion.

Compare like with like: the same URL, record type, tool, and approximate conditions. DNS answers can differ by resolver and cache. A page can respond differently to browsers, networks, or user agents. A missing RDAP field can be redacted or unsupported. A generated snippet is output to inspect, not a change already applied to your site.

Accounts

Registration And Access Requirements

Most tools are public by default. A browser session has three free tool tests before the site asks the visitor to register. The current registration form accepts valid Gmail, Yahoo, Hotmail, Outlook, and iCloud addresses and requires email verification. The account-only tools in the directory are Rank Tracking and Saved SEO Reports; both have implementation limits explained in their own guides. An administrator can also change tool visibility, guest access, verification requirements, or quotas.

Account screens, projects, reports, email verification, and CMS administration require PostgreSQL and working email delivery where a flow sends a message. SMTP is not configured in this environment, so email verification and password reset delivery are not operational until the site owner sets up and tests a mail provider. Do not rely on an account feature unless the page confirms that it succeeded.

Use the registration page only with an email address you control. Keep the password private and do not share one-time verification or reset links.

Persistence

Saving, Reviewing, And Exporting Results

Projects, audit history, and saved reports depend on the account database. A tool result displayed in the browser is not necessarily saved. Use the account page only after the application has confirmed a save. The Saved SEO Reports tool is account-only and requires a configured database; its description should be read alongside the current tool status.

There is no general export-to-PDF or bulk-report export feature documented as available in this release. Some generators return text or markup that you can copy for review. A copied result is not a stored report. Keep your own secure record of any important output and avoid storing confidential data in a tool response.

Core Concepts

SEO Fundamentals That Help Interpret Checks

  • Crawlability and indexability: Crawlers need to reach a page; a reachable page is not automatically eligible for indexing. Robots directives are not access control.
  • HTTP status and redirects: Status codes describe the response. Redirects tell clients to request another URL; a single final response is not always a full redirect-chain analysis.
  • Canonical URLs: A canonical tag is a signal about a preferred equivalent page, not an absolute command to a search engine.
  • Titles and descriptions: Metadata can help describe a page, but character guidance is not a ranking guarantee and search engines may display different text.
  • Headings and alt text: Headings organize visible content; alternative text provides an equivalent for meaningful images. Neither should be filled with repetitive keywords.
  • Sitemaps and robots.txt: Sitemaps list URLs that a site wants discovered; robots.txt guides cooperative crawlers and does not secure private pages.
  • Structured data: Valid JSON does not guarantee eligibility for a rich result. Search engines apply separate policies and may choose not to show enhanced results.
  • DNS and TTL: DNS resolvers cache record answers for a time-to-live. Different answers can reflect caching or configuration; there is no single global propagation switch.
  • Search demand and rankings: Local keyword suggestions do not supply search-volume data. Manual rank notes are not live ranking measurements.
  • Backlinks and field performance: A user-provided CSV is not a complete backlink index. Lab or field Core Web Vitals require a real measurement source that is not configured in this release.
  • Social previews and crawler directives: Open Graph and X card tags describe sharing metadata. AI crawler checks inspect published directives rather than measuring AI search presence.

Troubleshooting

Common Problems And What To Try

  • Invalid URL or domain: Check the spelling and use the format requested. Add https:// for a URL field; omit it for a domain-only field.
  • Invalid IP: Remove spaces and punctuation that are not part of the address. Use a public target you are authorized to check.
  • Website unavailable or timeout: Open the URL in a browser, confirm redirects and access controls, then retry later. A timeout does not prove the site is down for everyone.
  • DNS record missing: Confirm the exact hostname and record type, then compare with the authoritative zone and a public resolver. A cached answer can persist until its TTL expires.
  • TLS error: Check hostname coverage, validity dates, chain configuration, DNS, and system time. Do not disable certificate validation to make a warning disappear.
  • HTTP error or redirect loop: Review the final URL and response status and inspect the site's own redirect configuration. The tool may not show every intermediate hop.
  • robots.txt or sitemap unavailable: Check the exact public path, response status, content type, and server rules. A robots directive does not protect confidential content.
  • Metadata or schema warning: View the source returned to the tool, validate the relevant markup, and compare it with visible page content. A syntactically valid schema is not a search result guarantee.
  • Unsupported or malformed CSV: Use the documented text/CSV format, keep a header row if requested, and try a small sample before analyzing a larger file.
  • Empty result or external provider error: Confirm the input and source availability. RDAP coverage, DNS providers, and target servers may be temporarily unavailable or return limited data.
  • Rate limit or account error: Wait before retrying, sign in when required, and complete email verification. Email-dependent features will not work until SMTP delivery is configured.
  • Missing Core Web Vitals: The current release has no real browser or authorized field-data provider. It will not invent measurements.

Sources And Accuracy

Data Sources, Accuracy, And Tool Limitations

Some results are computed locally from supplied text or code. Website inspections fetch a public page and analyze the response available to the server. DNS lookup uses the configured resolver; DNS comparison samples Google Public DNS and Cloudflare Public DNS. RDAP/domain-age checks depend on the public RDAP service and registry records. These sources can be incomplete, cached, redacted, rate-limited, or temporarily unavailable.

There is no configured commercial keyword-volume, live ranking, backlink-index, competitor-ad-spend, payment, or browser field-data provider. No live values are fabricated for these missing sources. The client code has an optional event hook, but no third-party analytics service is configured by default. The site owner must disclose any provider added later.

The application does not currently save anonymous visitor IP addresses or country/region to its own database. Tool usage rows may store a tool identifier, account identifier when signed in, and timestamp if PostgreSQL is configured. Hosting and network providers may keep separate access logs under their own policies; their retention is not established by this page.

Security And Privacy

Use Tools Responsibly

Check only websites and systems you own or have permission to assess. The tools are for bounded public diagnostics, not port scanning, exploitation, internal network access, or bypassing access controls. The fetch layer applies public-address, redirect, timeout, response-size, and rate protections, but no control is a guarantee against all misuse. Review the Acceptable Use Policy, Security Policy, Privacy Policy, and Cookie Policy.

Cookie dismissal is remembered for thirty days but does not grant advertising consent. Ads are optional and not configured by default. A suitable consent mechanism is not currently integrated; the operator must address regional requirements before enabling ads for visitors who need prior consent.
