Resources & User Guide

Auditing a website takes three steps: enter the full URL (including https://) into the address bar at the top of the dashboard, optionally open Crawler Configuration to tune limits, then press Launch. The crawler discovers your sitemap, traverses the internal link graph, validates every response, and streams results into the dashboard in real time.

• Discovery & Validation: the top status cards show how many URLs were discovered, how many were successfully validated (with a live percentage), any anomalies encountered, and the average server latency in milliseconds.
• Crawl limits: the engine is optimised as a dedicated technical crawler and scales from quick 10-page spot checks to full 10,000-page deep audits. The crawler respects robots.txt automatically.
• Wait times: deep scans of large domains take several minutes — every page is parsed for titles, meta tags, headings, scripts, structured data, HTTP headers and indexability signals.
• Session controls: use Erase Data to clear the current crawl, the filter box to narrow any table instantly, and the export buttons to download reports.

Before launching, click the gear icon next to the Launch button to fine-tune extraction behavior and traversal limits. Saved settings apply to every future crawl.

The Rendering Engine section controls how pages are fetched and parsed, so both server-rendered and JavaScript-heavy sites can be audited accurately. Click Save Configuration to apply.

As soon as a crawl completes, the main dashboard gives you a single-screen picture of your website's technical health:

• Technical Health gauge: a composite score (0–100%) combining on-page, performance and security signals, with sub-scores for HTTPS security and a breakdown of assessed categories.
• Crawled Pages breakdown: every crawled URL classified as Healthy, Broken, Have Issues, Redirects or Blocked, with a colour-coded progress bar.
• Errors & Warnings trend: distribution charts of critical errors and warnings across the crawl so you can see whether problems cluster in one section of the site.
• Toolbar: filter results instantly, generate an AI Summary, erase crawl data, or export the report.

Modern search happens in AI assistants as much as in classic search engines. The Blocked from AI Search (robots.txt) panel parses your robots.txt and reports, bot by bot, whether the crawlers that power AI answers can access your site:

• ChatGPT-User — the agent used when ChatGPT browses on a user's behalf.
• OAI-SearchBot — OpenAI's search indexing crawler.
• Googlebot — Google's classic search crawler.
• Google-Extended — the token controlling use of your content in Google's AI models.

Each bot shows an All Good badge when allowed, or a warning when your robots.txt is silently blocking it — a bot access policy to review against your intended settings; this does not establish AI-answer visibility.

The Critical Diagnostics panel ranks every detected problem into High Impact and Medium Impact priority bands, each tagged as an SEO or Performance issue with the number of affected pages and a How to fix guide:

• SEO issues: duplicate titles, missing meta descriptions, duplicate meta descriptions, titles too long or too short.
• Performance issues: slow responses, large resource payloads and compression checks.

Click any page count to jump straight into the affected URLs, or View All Issues to open the full Diagnostic Issue Log.

The Diagnostic Issue Log is the master audit view: a total error counter, a pages-with-issues counter, a one-click Summarize with AI button, and every check organized by category. Each issue card shows its impact level (Critical, High, Medium or Low) and how many pages are affected:

Alpha Crawler works in both directions — from issue to pages, and from page to issues:

• Click an issue and the Affected URLs subtab opens with the matching pages and resources, with a removable "Filtered by" chip at the top.
• Click a page and its Automated Diagnostic Data expands, listing every issue found on that page as red badges — for example Not in Sitemap, Title Too Long, Duplicate Meta Description, H1 Balance Mismatch, Render Blocking Resources, Unused JS Execution and Large JS Payload Size.
• Click Full Page Details to open the complete URL Diagnostic Insights report for that single URL.

The Full Page Details view is a complete technical X-ray of one URL, organized into four zones:

A fifth zone — the Structured Schema Engine — validates the page's structured data and is covered in Schema Analysis.

Understand how your website is structured — and how deep your content is buried — with two complementary views:

• Directory List: every crawled URL grouped by directory level (Level 0, Level 1, Level 2…), each row showing the HTTP status code, full URL, indexability badge and word count. Click any page to jump into its page-level diagnostics.
• Horizontal Tree: an interactive node graph of the entire site — domain → folders → pages — with the status code on every node. Pan and zoom freely, and use Graph Settings to adjust level spacing, node spacing, text size and link/background/text colours, or restore initial settings with one click.

The Internal Pages table is the full inventory of every HTML page discovered in the crawl, in one sortable, filterable, exportable grid. Columns include:

• Address & Status: the full URL with its HTTP response code and indexability verdict.
• Metadata: Title 1 with title length, Meta Description 1 with description length, and H1 with H1 length — spot truncation and duplication instantly.
• Content signals: word count and text-to-HTML ratio per page.
• Link equity: inlinks and outlinks counts for every URL.
• Speed: per-page response time (load time) in milliseconds.

Columns are resizable, the filter box narrows the table live, and the whole grid exports to CSV.

Beyond HTML pages, the crawler inventories every supporting resource your website loads — JavaScript files, stylesheets, images and other assets — each listed with its own HTTP status code, so broken scripts, missing images and dead CSS references surface immediately instead of silently degrading pages.

• Filter assets instantly and export the full inventory for your dev team.
• Combine with the Unused JS Execution check to find scripts loaded across the site that never run.
• The same Discovery / Validation / Anomalies / Latency status cards track the asset crawl in real time.

The Analytics view condenses the whole crawl into site-wide statistics:

• Internal Connectivity: total internal link edges — the strength of your internal linking graph.
• Semantic Density: average words per page across the site.
• Infrastructure Health: the 200 OK success rate across all requests.
• Protocol Coverage: percentage of SSL/TLS-verified nodes.
• Depth Distribution: a bar chart of how many pages sit at crawl depth 0, 1, 2, 3… — deep-buried content is harder for users and crawlers to reach.
• Status Codes Mix: a donut chart of every HTTP status code returned across pages and internal assets.

Structured data powers rich results and helps AI engines understand your content. Alpha Crawler analyzes schema markup at two levels:

• Site-level Schema Distribution: a website-wide structural footprint — a donut chart of every schema type detected across all pages (WebPage, WebSite, Organization, BreadcrumbList, ImageObject, Article, Person, CollectionPage and more) with the total analyzed page count.
• Page-level schema list: under All Analyzed HTML Pages, filter by URL and see badges of every schema type implemented on each individual page — instantly spot pages missing Article or Breadcrumb markup.
• Structured Schema Engine (per URL): inside Full Page Details, every JSON-LD entity on the page is expanded property by property — @type, @id, url, name, publisher, itemListElement and the rest — with an error counter per entity, so you validate your markup exactly as a search engine parses it.

The Source Code Distribution report is a whole-website footprint analysis: a donut chart of the total asset count broken down by type — HTML, CSS, JavaScript, Images and Other — with the overall total in the center.

An image-heavy or JS-heavy footprint is an early warning for page-weight and Core Web Vitals problems; pair this chart with the Large JS Payload and Scripts & Assets reports to find exactly which files to optimize.

Connect your chosen provider to reveal AI Summary in the crawl toolbar. Summaries explain aggregate technical evidence and the order of fixes. Without a connection, the summary control stays hidden.

• AI summaries convert raw crawl data into a plain-language, prioritized action plan: what's broken, why it matters, and what to fix first.
• Connect your chosen provider in AI Connections. OpenAI, Gemini, Claude and compatible APIs are supported; the summary button appears after a successful connection.
• Summaries are generated on demand — nothing is sent to the AI until you click the button.

Export filtered URL tables as CSV and the audit action plan as PDF using the export button on each panel — Internal Pages, Scripts & Assets, the Diagnostic Issue Log, filtered issue views, analytics and schema reports.

• Exports respect the current filter — filter to one issue, export only those URLs.
• CSV can be opened in Excel or Google Sheets. PDF action plans contain the prioritised audit findings.
• Hand a filtered export to a developer as a ready-made fix list, or archive full crawls for before/after comparisons.

Connect Google Search Console to enrich your crawl with real-world search performance — clicks, impressions and ranking data for every page. Connect using your own Google account:

• Sign in to your Alpha Crawler account and click Connect Google.
• Choose a Google account with access to your Search Console and GA4 properties.
• Approve read-only access, choose a property and click Load report.

Google access lasts for the current session until the token expires. Saved account reports may include analytics snapshots; scheduled crawls do not refresh Google metrics in the background.
