You've created your online shop. You've taken care of your product sheets, set up your payment methods and paid your delivery charges. And you're waiting. Visitors aren't coming, or not enough. You're wondering what's going wrong.
The answer is often where you don't look first. Not in your products. Not in your prices. In what Google sees when it analyses your site before deciding whether or not to send you customers.
Online sales SEO is not a subject reserved for developers or digital agencies. It is a set of concrete, documented and actionable criteria that any merchant can understand and improve. Here's what Google really looks at.
What Google does before your customers even arrive
Google is not a passive directory. It is an active system that constantly explores, analyses and classifies billions of pages. This process is called crawling and indexing. Automated robots called Googlebots regularly crawl your site to read its content, analyse its structure and assess its quality.
If your site is badly structured, too slow or technically deficient, these robots spend less time on your pages. They index less. And you lose positions in the search results before you even have a chance to be seen.
The first criterion that Google evaluates is your technical accessibility. Does your site load quickly? Is it readable on mobile phones? Are your pages well linked? These are the basic questions. Without a satisfactory answer to each of them, everything else is built on sand.
SEO online sales: loading speed, a criterion that costs sales
In 2021, Google has made official the integration of Core Web Vitals in its ranking algorithm. These indicators, published and documented publicly by Google Search Central, measure three dimensions of the user experience: the speed with which the main content is displayed, responsiveness to interactions and the visual stability of the page during loading.
For an online shop, these indicators are doubly important. They influence your positioning in search results. And they directly influence the behaviour of your visitors. Studies published by Google and Deloitte on the impact of mobile speed on conversions show that an improvement of just one second in loading time can increase conversions by up to 27% on certain types of site. e-commerce sites.
In other words, a slow site doesn't just lose Google positions. It loses customers who would have bought if the page had been displayed faster. Speed is not a technical detail. It's a direct commercial argument.
Content: what Google reads and what it values
This is where many online merchants under-invest. They devote energy to their product photos and neglect their texts. Google doesn't see your photos. It reads your words.
A product page without a substantial text description is virtually invisible to search engines. Google can't guess what you're selling from an image. It needs text to understand what the page is about, assess its relevance to a given query and decide where to display it.
The concept of search intent is central to the way Google evaluates your content. For each query typed by an Internet user, Google seeks to identify what that person really wants. Buying a specific product, comparing options, getting information before making a decision. If your content responds exactly to this intention, you have a serious chance of appearing in a good position. If your content is generic, poorly targeted or insufficiently developed, you will be lost in the crowd.
For online sales SEO, this means that each product sheet must answer the real questions your potential buyers are asking. Not just describe the product. Anticipating objections, detailing uses, specifying features that make a difference.
The structure of your site: what Google uses to understand your world
Google does not read your site page by page in isolation. It understands your site as a coherent or incoherent whole, depending on how your pages are linked together.
Internal linking, i.e. the links you create between your own pages, plays a crucial role in the way Google distributes what is known as page authority across your site. A page that is well linked to other relevant pages in your shop receives more relevance signals. An isolated page, with no inbound links from the rest of your site, is much less valued.
For an online shop, this means that your categories should point to your product sheets, your blog posts should link to the relevant products, and your home page should clearly point to your main categories. This architecture is not only useful for Google. It also guides your visitors and reduces the abandonment rate.
SEO online sales: domain authority, what other sites say about you
Google doesn't just read your site. It also observes what the rest of the web is saying about you. Inbound links, known as backlinks, from other sites to yours are interpreted by Google as votes of confidence. The more these links come from recognised and relevant sites in your sector, the more they reinforce what SEO specialists call domain authority.
This concept, formalised in Moz and Ahrefs research on Google ranking factors, is one of the most powerful signals in the algorithm. A site with few pages but well referenced by outranked quality sources often has a large site but no serious inbound links.
For a start-up online shop, building this authority takes time. Effective strategies include publishing expert content that other sites will want to quote, being listed in recognised industry directories, partnering with relevant content creators in your field and digital press relations.
The mobile experience: Google's top priorities for 2019
Since Google's full roll-out of mobile first indexing in 2019, officially documented by Google Search Central, it is the mobile version of your site that serves as the main reference for indexing and ranking. Not the desktop version.
This means that if your online shop is perfectly optimised on a computer but difficult to navigate on a phone, you will be penalised in the search results, even for users searching for you from a computer. The logic may seem counter-intuitive. But it has been documented and confirmed for several years now.
Check that your buttons are large enough to be clicked with a finger, that your text is legible without zooming, that your order forms work without friction on a touch screen, and that your images don't slow down mobile loading. These are concrete adjustments that have a direct impact on your online SEO.
Structured data: speaking Google's language
This is one of the most underused levers for independent online merchants. Structured data are code tags, based on the Schema.org vocabulary supported by Google, Microsoft and Yahoo, which allow your site to communicate directly with search engines in a standardised language.
For an online shop, this data enables Google to display enriched information in the search results: the price of your product, its availability in stock, its average rating and customer reviews. These rich snippets significantly increase the click-through rate from Google results, even without any improvement in position.
A product displayed with its rating and price directly in the search results attracts more clicks than a simple blue link. And more clicks means more positive signals sent to Google, which can in turn improve your ranking.
SEO online sales: what you need to remember before taking action
The natural referencing of an online shop is not a one-off action. It's an ongoing, progressive process that produces lasting results if it's carried out methodically.
Google doesn't send you customers by chance. It sends them to you because your site responds better than others to what these customers are looking for, because it loads quickly, because it is technically sound, because it is cited by other trusted sources, and because it offers a fluid experience on all devices.
Each of these criteria can be improved. None requires an unlimited budget. All require consistency.

To take your strategy a step further, here are some themes to explore: Core Web Vitals Google Search Central, mobile first indexing Google, structured data Schema.org e-commerce, search intent SEO content, online shop internal linking, domain authority backlinks strategy, mobile loading speed e-commerce conversion, and technical SEO audit e-commerce site.
Online SEO is the most profitable investment you can make in your shop. Not because it's fast. Because it lasts. A customer who found you organically via Google cost you nothing in advertising. And if your site really is what they're looking for, they'll come back.
