Summary
Why use free tools to analyze your store's SEO?
SEO is not always complicated or expensive. Many tasks can be done in-house with free tools that analyze aspects of your site to help you resolve problems or errors. It is an accessible approach, even for small online stores.
By using these tools, you maintain control over your SEO strategy without depending on expensive agencies. You can quickly identify the weak points of your pages and correct them yourself, which improves your visibility on search engines.
However, it is important to know that not all problems can be detected with free tools. Some require technical expertise, but for most cases, these solutions are more than enough. Furthermore, these tools allow you to understand the basics of SEO, which is a valuable asset for your entire team. By integrating them into your routine, you develop an internal SEO culture that benefits your store in the long term.

How does Google Search Console reveal your site's errors?
Google Search Console is an essential tool for any online merchant. It provides an incredible amount of information about the health and performance of your site, including:
Rankings: the queries that drive traffic to your site.
Load times: the speed of your pages and their mobile-friendliness.
Traffic drops: drops in rankings and organic traffic.
Inbound links: backlinks to your site along with their anchor text.
Manual actions: warnings or penalties from Google.
However, Search Console has its limitations: it only retains 16 months of data, and the links report is inaccurate. For a complete analysis, combine it with other tools. For example, use the performance report to spot pages that are losing clicks, then cross-reference this data with Lighthouse results to identify technical causes. This approach allows you to prioritize the most impactful fixes.
Which tool should you use to compare your pages with those of your competitors?
Comparing your pages with those of your competitors is an excellent way to identify your weaknesses. The Page Comparison tool from Webmaster World highlights the differences at a glance, including:
Word count: compare the length of your content.
Keywords: spot two- or three-word phrases that your competitors are focusing on.
HTML tags: compare the structure of your pages.
Internal and external links: see which links are present on each page.
The Spider Test tool from SEO Book offers a similar analysis, but for only one page at a time. Open multiple tabs to easily compare. By analyzing your competitors' pages, you can discover keyword opportunities you hadn't considered. For example, if a competitor uses specific terms in their title tags, you can integrate them into your own strategy to stay competitive.
How does the Google cache help in understanding the interpretation of your pages?
Google cache is the easiest way to understand how Google interprets a page. It displays a text-only version, where images appear as alt text, and JavaScript and CSS are removed.
This gives you a clear view of your page, revealing:
Invisible elements: content generated by JavaScript that Google cannot index.
Alt texts: image descriptions that make no sense.
Check the Google cache for any page, your own or a competitor's, as long as the site has not blocked Google's access. This check is quick and can reveal major issues, such as important content not being indexed. By fixing these points, you improve the visibility of your pages and avoid losing valuable traffic.
Which extension can be used to detect broken links on your pages?
Broken links and redirects harm the user experience and send bad signals to Google. It is therefore crucial to regularly check all the links on your pages. Several free tools can analyze and fix these issues.
Check My Links, a Chrome extension, is an effective example. It colors the links on a page:
Green: active links.
Light green: valid redirects.
Red: broken links to fix.
LinkMiner is a similar extension. For WordPress, Broken Link Checker is a free plugin that identifies and fixes broken links and redirects. By regularly cleaning up your links, you improve your visitors' experience and avoid Google penalties. Remember to also check internal links, as they play a key role in your site's internal linking structure.
How does Google Lighthouse identify technical issues?
The previous tools mainly identify issues that are easy to fix. Google Lighthouse, although free, can identify problems that likely require an expert. It is part of Chrome's development tools.
Lighthouse evaluates a page on several aspects:
Performance: a Core Web Vitals test that evaluates load times and mobile functionality.
Accessibility: highlights elements that are difficult to read or use for people with disabilities.
SEO: checks meta tags, structured data, and more.
Use Lighthouse to get a complete diagnosis of your pages and prioritize fixes. For example, if the performance score is low, you can optimize images or reduce script weight. These technical improvements have a direct impact on your ranking and your users' experience.
What are the benefits of free SEO tools?
Free tools offer many benefits for e-commerce merchants. They allow you to perform regular analyses without impacting your marketing budget. This way, you can continuously monitor the health of your site.
In addition, these tools are often simple to use, even for beginners. They provide clear and actionable data, allowing you to make informed decisions to improve your SEO.
Finally, they help you remain independent. You don't need to call in an expert for every minor issue, saving you time and money. By using them regularly, you develop internal expertise that makes you more responsive to algorithm changes and new SEO trends.
How to integrate these tools into your overall SEO strategy?
To get the most out of these tools, integrate them into a regular routine. For example, start with Google Search Console to monitor performance, then use Page Comparison to analyze your competitors.
Next, check the Google cache to understand how your pages are interpreted, and use Check My Links to detect broken links. Finally, run Lighthouse for a complete technical audit.
By combining these tools, you get a comprehensive overview of your SEO and can prioritize the actions to take. This allows you to gradually improve your visibility and attract more qualified traffic. Schedule these analyses every month to track your site's progress and adjust your strategy accordingly.
What are the limitations of free SEO tools?
Although very useful, free tools have limitations. For example, Google Search Console only retains 16 months of data, which limits historical analysis. Furthermore, the link report is inaccurate, requiring third-party tools for a complete view.
Some tools only work on one page at a time, which can be tedious for large sites. Finally, complex issues, such as those related to custom code, often require the intervention of an expert.
It is therefore important to know when to use these tools and when to call on a professional to avoid wasting time. By knowing their limits, you can better plan your actions and avoid relying solely on incomplete data.
How to know if you need to hire an SEO expert?
Not all SEO problems can be identified or fixed in-house. Many can, especially for small and medium-sized online stores. However, larger sites, with custom code and complex features, usually require professional help.
If you notice recurring technical issues that free tools do not resolve, or if your organic traffic is stagnating despite your efforts, it may be time to consult an expert.
An expert will be able to perform an in-depth audit and implement tailored solutions to improve your SEO. They can also advise you on long-term best practices, such as creating quality content or optimizing your internal linking.
How does Qstomy help improve your store's SEO?
Qstomy, the Shopify AI agent, does not just improve the shopping experience. By guiding visitors to the right products and optimizing the cart, it increases the time spent on your site and reduces bounce rates, two positive signals for Google.
In addition, Qstomy helps with conversion by recommending complementary products, which increases the average order value. A site that converts well is often better positioned, as Google sees this as a quality user experience.

Set up Google Search Console: verify that your site is properly connected.
Compare your pages: use Page Comparison to identify gaps with your competitors.
Check the Google cache: verify how your pages are interpreted.
