SEO & Website Tools by Web Aloha

Website Health Check

Pre-check one public page for performance, mobile markup, discoverability and security signals. Read plain-English findings, scope limits and the next step.

WordPress PHP Upgrade Checker

Review WordPress Site Health and plugin metadata against a target PHP version, flag stale or unknown dependencies, and build a safer staging plan.

Sitewide Duplicate Content Finder

Compare up to 50 same-host pages from a crawl or supplied inventory for exact and near-duplicate groups, canonical signals and exportable review recommendations.

SEO Migration Redirect Mapper

Match old and new URL inventories with explainable confidence, review conflicts, check live redirects and export draft rules for implementation review.

GSC Opportunity Analyzer

Analyze Search Console CSV exports for striking-distance queries, CTR opportunities, content decay, won and lost visibility, brand mix, and query-page overlap.

Local SEO Landing Page Audit

Audit a local landing page for service and location relevance, NAP evidence, LocalBusiness schema, trust signals, contact paths, metadata, and internal links.

WordPress to Astro Assessment

Assess whether a WordPress website suits a full Astro migration, a hybrid architecture, or staying on WordPress based on content, workflows, integrations, and dynamic features.

Hreflang Checker

Inspect HTML and HTTP hreflang declarations, code shapes, self-references and bounded return links. Optional x-default and registry validation need contextual review.

HTML Lang Attribute Checker

Inspect the HTML lang attribute and its syntax. This does not validate the full BCP 47 registry or detect the actual language of page content.

HTTP Header Viewer

Inspect headers on the final response, including caching and security-header presence. Use Redirect Checker to investigate individual hops.

IP Canonicalization Test

Check whether a direct HTTP request to the first resolved IPv4 address redirects to the hostname. Shared hosting and CDNs can fail this narrow routing test by design.

RSS Feed Validator

Free RSS and Atom feed validator. Parse any feed URL, preview items, and check for required elements, dates, and structure problems that break readers and AI crawlers.

Broken Image Checker

Test up to 40 unique image references discovered in one page’s server HTML. See request status and sampling limits; JavaScript and alternate srcset images may be missed.

WordPress Version Checker

Inspect public WordPress version clues in metadata, feeds, readme and asset URLs. Verify the installed version and update state in the authenticated dashboard.

XML-RPC Exposure Checker

Inspect WordPress XML-RPC reachability and supported-method signals. Review integration needs and authentication controls; exposure alone does not establish exploitability.

WP Login Exposure Checker

Check public reachability of wp-login.php and wp-admin and review response evidence. A reachable login is an exposure signal, not proof it is unprotected or vulnerable.

Email Privacy Checker

Free email privacy checker. Scan any page for plain-text email addresses exposed in the HTML or mailto links that spam bots harvest, and learn how to protect them.

Domain Hosting Checker

Inspect public DNS, the first IPv4 address and provider clues. A CDN or proxy can hide the origin host, so treat provider labels as evidence to verify.

DNSSEC Checker

Check DNSSEC record publication and sampled resolver validation evidence. Record presence alone does not confirm a valid chain of trust.

Readability Score Checker

Estimate English reading difficulty with six formulas and word, sentence and syllable counts. Use scores as editing prompts for your audience.

Reading Time Calculator

Free reading time calculator. Paste text to estimate reading and speaking time, word count, and characters, with adjustable words-per-minute for blogs, scripts, and speeches.

JSON-LD Formatter

Free JSON-LD formatter. Beautify, minify, and validate JSON-LD structured data syntax, with error reporting and a ready-to-paste script tag for schema markup.

HTML to Markdown Converter

Free HTML to Markdown converter. Paste HTML and convert it to clean Markdown for docs, README files, llms.txt, and AI content. Runs entirely in your browser.

Markdown to HTML Converter

Free Markdown to HTML converter. Turn Markdown into clean, semantic HTML with a live preview and copy-ready output. Great for blogs, emails, and documentation.

URL Encoder / Decoder

Free URL encoder and decoder. Percent-encode or decode URLs, query strings, and components instantly, with full and component modes. Private and browser-based.

HTML Entity Encoder / Decoder

Encode or decode named and numeric HTML entities locally. Choose output for the intended context; entity encoding is not a general HTML sanitizer or complete XSS defense.

Base64 Encoder / Decoder

Free Base64 encoder and decoder. Encode text to Base64 or decode it back instantly, with UTF-8 support and URL-safe mode. Runs locally in your browser, no upload.

Regex Tester

Free regex tester. Build and debug JavaScript regular expressions with live match highlighting, capture groups, flags, and a quick reference. Private, browser-based.

Cron Expression Generator

Build five-field Unix cron expressions and preview times in your browser time zone. Verify the target scheduler dialect; WP-Cron uses a different scheduling model.

SVG Optimizer

Free SVG optimizer. Clean and minify SVG code by stripping metadata, comments, and editor cruft to shrink file size for faster icons and logos. Runs in your browser.

CSS Clamp Generator

Free CSS clamp generator. Create fluid, responsive font sizes and spacing with clamp() based on your min and max viewport, with copy-ready CSS and a live preview.

CSS Minifier

Reduce CSS whitespace and comments locally with selectable text transformations. Review the result; this is not a full semantic CSS optimizer.

JavaScript Minifier

Minify JavaScript with Terser in your browser. Review compression options and test the output; this does not bundle dependencies or guarantee faster interactions.

HTML Minifier

Apply selected HTML whitespace and comment reductions in your browser. Review rendered output because text-based transformations can affect content spacing.

Open Graph Generator

Draft Open Graph and Twitter Card tags from your inputs, with representative social previews. Review page facts and image requirements before publishing.

.htaccess Generator

Free .htaccess generator. Build Apache rules for redirects, HTTPS forcing, www canonicalization, caching, compression, and security headers in seconds.

Free SEO-friendly URL slug generator. Convert any title into a clean, lowercase, hyphenated, stop-word-trimmed slug ready for blog posts, pages, and products.

Color Converter

Convert HEX and comma-separated RGB/RGBA or HSL/HSLA sRGB values in your browser, with a color preview and contrast hints.

Keyword Density Analyzer

Analyze pasted text for one-, two- and three-word frequency and density. Review repetition in context; there is no fixed safe SEO percentage.

Favicon Generator

Generate six PNG favicon sizes from a local image or letter, with draft link tags. No ICO, SVG, ZIP or complete manifest output.

Markdown Extractor for LLMs

Extract text from public server HTML as Markdown for LLM inputs, optional site-guide drafts and content audits. JavaScript-only content may be absent.

Image Compressor

Free image compressor and WebP converter. Compress JPG and PNG images and convert to WebP in your browser to cut page weight and boost Core Web Vitals. No upload.

wp-config.php Generator

Draft a WordPress configuration with database inputs, generated keys and optional constants. Review against the existing installation before deployment.

Core Web Vitals Checker

Request PageSpeed Insights lab diagnostics and available CrUX real-user LCP, INP and CLS. Field data can be unavailable for low-volume URLs.

GZIP / Brotli Test

Inspect Content-Encoding and estimate transfer savings when Content-Length is available. Missing or intermediary-modified sizes limit the estimate.

HTTP/3 & HTTPS Signals

Check HTTPS redirects and HTTP/3 Alt-Svc advertisements. The tool cannot confirm negotiated HTTP/2 or HTTP/3 connections.

Page Weight Checker

Estimate known transfer bytes from server HTML and a bounded resource sample, with request coverage and missing-size limits. Runtime requests are not included.

X-Robots-Tag Checker

Inspect noindex and other directives in response headers and server HTML. A result without noindex does not establish Google indexing eligibility.

Mixed Content Checker

Find HTTP resource references in returned HTTPS page markup. Verify browser upgrading or blocking in the Network panel; runtime and external CSS requests can be missed.

DNS Propagation Checker

Compare sampled DNS answers from Cloudflare, Google and AdGuard recursive resolvers. Agreement is not proof of worldwide propagation.

WP REST API Exposure Checker

Review public WordPress REST endpoint responses and published author or content exposure. Public data can be intentional; reachability alone is not a vulnerability.

Favicon Checker

Inspect declared icon links, size attributes and a web-manifest link. Preview icons; manifest JSON and image pixels are not validated.

Spider Simulator

Inspect server-returned HTML text, links, headings and metadata without rendering JavaScript. This is not the rendered view used by Googlebot.

Website Carbon Calculator

Free website carbon calculator. Estimate the CO2 emissions of any web page based on its data transfer and energy use, and learn how to make your site greener.

Font Self-Hosting Helper

Turn a Google Fonts CSS URL into local font-face CSS and a WOFF2 download list. Review licenses, subsets and loading behavior before comparing performance.

Online PHP Version Checker

Check whether a public response exposes a PHP version clue. Review the exact header or page signal, evidence strength, tested URL, request outcome, and official support status.

DNS Lookup Tool

Free online DNS lookup tool. Check A, AAAA, CNAME, MX, TXT, NS, SOA, SRV and CAA records for any domain instantly.

Inspect public WordPress clues, exact theme and plugin asset paths, child and parent theme candidates, exposed stylesheet metadata, plugin slugs, and evidence limits.

SSL Certificate Checker

Free online SSL certificate checker tool. Verify SSL/TLS certificates, check expiry dates, issuer details, protocol version, and HSTS status for any website.

Open Graph Checker & Preview

Inspect server-HTML Open Graph and Twitter Card tags with representative social sharing mockups. Live platform fetches, cache state and image pixels are not validated.

Schema Markup Validator

Find public clues about what a website is built with. Check its CMS or platform, frameworks, analytics, hosting, CDN, fonts, and ecommerce tools, with confidence labels and clear detection limits.

Broken Link Checker

Free online broken link checker tool. Scan any page for dead links, find 404 errors, server errors, and connection failures on both internal and external links.

Keyword Extractor

Extract multilingual one-, two-, and three-word terms from pasted text or a public HTML page. Distinguish exact frequency from importance, with stopword handling, page fields, and source snippets.

Keyword Generator

Free online keyword generator tool. Enter a seed keyword and instantly get 100+ long-tail keyword ideas, questions, modifiers, comparisons, and intent-based variations for SEO and content planning.

Heading Checker

Inspect server-returned H1-H6 and ARIA headings, accessible names, levels, IDs, landmarks, title-to-H1 alignment, hidden headings, and outline review items.

Website Font Checker

Find font declarations in public HTML and CSS, including families, sources, weights and stacks. Browser-rendered fonts and image-based font identification need separate checks.

Canonical URL Checker

Free online canonical URL checker tool. Validate canonical tags, detect issues like chains, loops, conflicts, cross-domain canonicals, and more.

WHOIS Domain Lookup

Free online WHOIS domain lookup tool. Check domain registration, expiration date, registrar, nameservers, domain age, DNSSEC status, and more.

Image SEO Checker

Free online image SEO checker. Scan any webpage for missing alt tags, modern image formats, lazy loading, dimensions, srcset, and filename SEO issues.

Accessibility Checker

Parse server HTML for selected alt, label, heading, language and landmark issues. An accessibility markup pre-check, not a rendered WCAG conformance audit.

Performance Checker

Inspect server response timing, HTML size, compression, caching and resource patterns. This single-fetch diagnostic does not measure a rendered browser load or Core Web Vitals.

SERP Preview Simulator

Draft approximate desktop and mobile search snippets with character counts, editable metadata and optional URL import. Actual Google results can differ.

Mobile-Friendly Checker

Pre-check mobile-readiness signals in server HTML, including viewport and markup patterns. Does not render layout, compute tap targets or measure mobile performance.

XML Sitemap Generator

Crawl up to 500 same-host HTML URLs or normalize a manual list, review redirect, response, canonical, meta robots, and X-Robots-Tag exclusions, then validate and export standards-based sitemap XML.

Duplicate Content Checker

Compare two public pages or pasted texts with shingle similarity, directional overlap, longest shared passage, and sentence-level evidence. URL mode analyzes server-returned HTML, not rendered JavaScript.

AI Search Visibility Checker

Run a free technical AI search visibility audit for crawler access, structured data, page structure, and discovery signals. Get a transparent readiness score and actionable checks; this is not citation tracking.
