SEO for online shops: the basics without the jargon

SEO has an industry around it that benefits from making it seem complex. It isn't simple - but the fundamentals that actually move the needle for a small ecommerce site are not complicated, and they don't require a monthly agency retainer to implement.

This guide covers what Google actually cares about for an online shop, what you can do during and after the build to establish good foundations, and what to be sceptical of when agencies pitch you on ongoing SEO services.

How Google sees your shop

Google's crawler visits your shop periodically, reads the content of your pages, and makes decisions about what those pages are about and how useful they'd be to someone searching for specific things. It then ranks your pages against other pages trying to rank for the same searches.

The factors Google weighs are broadly:

• Relevance - does the page actually answer the search query?
• Quality - is the content original, detailed, and trustworthy?
• Technical factors - is the page fast, mobile-friendly, and properly structured?
• Authority - do other reputable sites link to yours?

For most small ecommerce sites, the biggest gains come from getting the technical foundations right and writing genuinely useful, original product content. Authority (links from other sites) builds over time and is harder to accelerate.

Technical foundations

These are the non-negotiables. A shop with poor technical SEO will struggle regardless of how good its content is.

Page speed. Google uses speed as a ranking factor. More practically, a slow shop loses customers before they buy - research consistently shows that every extra second of load time reduces conversions measurably. Aim for pages that load in under 2 seconds. Platform-based shops (especially WordPress with many plugins) are often slow by default.

Mobile-friendly design. Google primarily indexes the mobile version of your shop. A shop that doesn't work well on a phone will rank poorly even for desktop searches. This should be built in from the start, not retrofitted.

Clean URL structure. URLs like `/antique-french-armoire-19th-century/` are better than `/products/12345/`. Descriptive URLs help Google understand what the page is about and appear in search results in a way that builds trust with users. Platform shops impose URL structures you can't always control.

Proper page titles and meta descriptions. Every page needs a unique, descriptive title tag - the text that appears in search results and browser tabs. Product pages in particular should have titles that reflect what someone would actually search for. "Handmade Oak Writing Desk - Free UK Delivery" is better than "Product 47".

Canonical tags. If the same product appears under multiple categories or with filter variations (colour, size), canonical tags tell Google which URL is the "main" version, preventing duplicate content penalties.

HTTPS. An SSL certificate is a basic requirement. Google flags non-HTTPS sites as insecure and ranks them lower. Any reputable hosting setup includes this.

Product page SEO

Product pages are where most ecommerce SEO is won or lost. They're also where most shops make the most easily avoidable mistakes.

Write your own descriptions. Copying supplier descriptions is the most common ecommerce SEO mistake. If 50 shops sell the same product with the same manufacturer description, Google has no reason to rank yours above the others. Original descriptions - even a few well-written sentences that say something genuine about the product - create unique content that differentiates your page.

Answer the questions customers ask. What dimensions is it? What material? How is it delivered? Will it fit through a standard door? The more completely a product page answers practical questions, the more useful it is - and useful pages rank better than thin ones.

Use descriptive image alt text. Search engines can't see images, but they read the alt text attribute. "Oak Writing Desk with Drawer - Side View" is more useful than "img_00473.jpg" for both Google and for visually impaired customers using screen readers.

Structured data. Adding product schema markup (price, availability, review rating) to product pages tells Google exactly what the page contains and can generate rich snippets in search results - star ratings, prices, and stock status shown directly in the search listing. This is a technical implementation, but a good bespoke build will include it.

Category pages

Category pages ("Antique French Furniture", "Handmade Ceramics") are often more valuable for SEO than individual product pages, because they match broader search queries that more people use. A well-written category page with a genuine introduction - not just a grid of products - performs significantly better than a blank filter page.

Most platform shops generate empty category pages automatically. Writing genuine introductory content for your main categories is one of the highest-return SEO tasks a shop owner can do themselves.

Local SEO

If your business has a physical location or serves a specific area, local SEO matters. Key actions:

• Claim and complete your Google Business Profile (formerly Google My Business)
• Ensure your business name, address and phone number are consistent across your website, Google Business, and any directories
• Include your location naturally in page content where relevant ("handmade ceramics from Cornwall")
• Encourage customers to leave Google reviews - review quantity and quality affect local rankings

Content as an SEO strategy

Guides, how-to articles, and informational content attract links and build topical authority over time. A ceramics shop that publishes detailed guides on caring for handmade pottery will, over months and years, attract links from other sites that reference those guides. Those links boost the entire domain's authority - including the product pages.

This is a long-term strategy, not a quick fix. But it's one of the few SEO approaches that genuinely compounds over time and doesn't require ongoing agency fees.

What to be sceptical of

Ranking guarantees. No one can guarantee a Google ranking. Google's algorithm is not for sale. Any agency promising specific rankings is either lying or planning to use tactics that will eventually harm your site.

"We'll submit your site to 500 directories." Directory submissions were relevant in 2005. They're not a meaningful SEO signal now and can do more harm than good if the directories are low quality.

Monthly retainers before the foundations are right. There's no point paying for ongoing content marketing if the technical foundations are broken, your product descriptions are copied from suppliers, and your pages load in six seconds. Fix the basics first.

Keyword density obsession. The idea that you need to mention a keyword a specific number of times per page is outdated. Google understands natural language. Write clearly and helpfully; the keywords will take care of themselves.
