Free Tools to Check Your Website’s SEO Health

A healthy website is easy for search engines to crawl, quick to load, useful on a mobile screen, and clear about what each page offers. You do not need an expensive software subscription to find many of the problems that reduce organic traffic. Several free SEO tools can reveal technical errors, slow pages, broken links, indexing issues, and content opportunities.

This guide focuses on practical tools for bloggers, small businesses, and website owners in Australia. Whether your audience is in Sydney, Melbourne, Brisbane, Perth, or regional areas, the same basic process applies: inspect the site, fix the highest-impact problems, and measure the results over time.

Start With Google Search Console

Google Search Console is the most important free resource for checking how your website appears in Google Search. After verifying your domain, open the Performance report to see clicks, impressions, average position, and click-through rate. Filtering by query, page, country, and device helps you understand whether your traffic comes from Australian searches, mobile users, or desktop visitors.

The Indexing reports show which pages Google has discovered, crawled, and excluded. Look for errors involving server responses, redirects, duplicate pages, or incorrect canonical URLs. The URL Inspection tool is useful when you publish an article and want to check whether Google can access it, whether the page is indexed, and which canonical address Google selected.

Search Console also reports Core Web Vitals using real user data. A page may perform well in a laboratory test but load slowly for visitors using mobile networks or older devices. This matters for users browsing during a commute in Sydney or Melbourne, or customers in regional Australia using less consistent connections.

Test Speed With PageSpeed Insights

PageSpeed Insights combines laboratory testing from Lighthouse with field data from the Chrome User Experience Report when enough data is available. Enter a page URL and review the scores for performance, accessibility, best practices, and SEO. Pay particular attention to Largest Contentful Paint, Interaction to Next Paint, and Cumulative Layout Shift.

The recommendations can identify oversized images, unused JavaScript, render-blocking files, and inefficient caching. A practical first step is to convert large photographs to WebP or AVIF, compress them before uploading, and serve appropriately sized images for mobile screens. A content delivery network and reliable Australian hosting can also help reduce delay for local visitors.

Do not treat a perfect score as the sole goal. A fast, readable page that earns enquiries is more valuable than a page that scores highly while offering a poor experience. Test important templates separately, including the home page, blog post, product page, contact page, and checkout screen.

Crawl Pages With Free Technical Auditors

Screaming Frog SEO Spider offers a free version that can crawl up to 500 URLs per website. It can find broken links, missing title tags, duplicate metadata, redirect chains, orphaned pages, oversized files, and pages blocked by robots.txt. This makes it especially useful for blogs that have accumulated years of articles and category pages.

Ahrefs Webmaster Tools is another useful option for verified websites. Its site audit checks crawlability, internal links, HTML tags, performance signals, and common technical SEO issues. The tool also provides a limited view of backlinks, which can reveal links from outdated pages or suspicious domains that deserve closer attention.

For a small WordPress website, run a crawl after a redesign, domain migration, or major plugin change. Review errors manually before making bulk edits. A page marked as a duplicate may be intentionally similar, while a redirected URL may be part of a carefully planned site structure.

Improve On-Page SEO and Content Quality

Google’s Rich Results Test checks whether a page contains structured data that Google can understand. It supports formats such as Article, Breadcrumb, Product, Event, and FAQ where the markup matches the visible content. Valid structured data does not guarantee a rich result, but errors can prevent eligible features from appearing.

Use Google Trends to compare search interest, related topics, and seasonal demand. Set the location to Australia when researching local services or consumer interests. Search behaviour for solar panels, air conditioning, school holidays, or tax-related services can vary by state and season, so national assumptions may produce weak content.

A free keyword tool can help generate ideas, but search results themselves are often more revealing. Examine the pages ranking for a target phrase and look for missing information, unclear explanations, or outdated advice. For Australian readers, use natural local language and spelling, such as “organisation” and “optimise”, while including relevant location terms only when they genuinely help the visitor.

Check Links, Security, and Mobile Experience

Broken internal links waste crawl resources and create frustrating dead ends for visitors. Google Search Console’s Links report shows which pages receive internal links, while a crawler can identify links returning 404 or 5xx responses. Link important guides from related articles using descriptive anchor text rather than generic phrases such as “click here”.

Run your site through Lighthouse in Chrome to review mobile usability, accessibility, and basic security practices. Check that text can be read without zooming, buttons have enough space, forms have clear labels, and images include useful alternative text. Test the website on an actual phone as well as a desktop computer because responsive layouts can fail at screen sizes that are not obvious in a browser window.

HTTPS is essential for trust and protects information submitted through forms. Website owners collecting names, email addresses, or customer details should also review their privacy practices under Australia’s Privacy Act. If a site sends promotional email or SMS, the Australian Spam Act 2003 requires consent and an appropriate unsubscribe process. Technical SEO should support lawful, transparent data handling rather than treating compliance as an afterthought.

Measure Local Search and Ongoing Progress

Google Business Profile is essential for businesses serving a particular area. Keep the business name, address, phone number, opening hours, services, and website URL consistent. Upload genuine photographs, respond to reviews professionally, and use the profile’s performance data to see which searches lead to calls, messages, or direction requests.

For a local business in Brisbane, Adelaide, or Hobart, create useful service pages that explain the areas served instead of producing dozens of near-identical pages with swapped suburb names. Include practical information such as delivery zones, appointment availability, parking, or regional service limits. Australian Consumer Law also makes accurate pricing, claims, guarantees, and testimonials important for trustworthy online marketing.

Use Search Console, Analytics, or a privacy-conscious alternative to establish a baseline before making changes. Record organic clicks, conversions, indexed pages, mobile performance, and important keyword positions once a month. A simple spreadsheet is enough. Compare similar periods because school holidays, weather, public holidays, and seasonal shopping can affect Australian traffic.

Run the same health check after publishing a large content batch, changing hosting, installing plugins, or redesigning navigation. Fix critical indexing and security problems first, then improve speed, internal linking, content depth, and conversion paths. This steady process produces clearer results than making many undocumented changes at once.

Use these free tools as a repeatable maintenance routine: inspect visibility in Search Console, test speed with PageSpeed Insights, crawl the site for technical errors, validate structured data, review local information, and track meaningful outcomes. Begin with the pages that attract visitors or generate revenue, apply the fixes carefully, and schedule a monthly check so small SEO problems do not become expensive traffic losses.
