Paris SEO Meetup 2023<\/a>).\n<\/p>\n<\/p>\n
On-Page optimisation of Category Pages<\/h2>\nPrimary and secondary keywords<\/h3>\n
\nOn a category page, the raw density of keywords n![\"E-commerce](\"https:\/\/www.france-webdesign.com\/wp-content\/uploads\/2025\/06\/Optimisation-des-Images-Reduire-la-Taille-des-Fichiers-sans-Perdre-en-Qualite-1.jpg\" "\\"SEO")
has not been a lever since Panda (2011).
\nOn the other hand, the integration of thematic co-occurrences remains decisive.
\nThe tool NLP<\/abbr> from Google (Cloud Natural Language API) often reveals lexical fields
\nwhich we naturally have to inject: trail material + anti-slip + low shank + gore-tex.
\nThe e-retailer Alltricks, by working with these entities, has gained +41 % of traffic on its Trail Shoes category between 2021 and 2022.\n<\/p>\nShort, descriptive URL structure<\/h3>\n
\n\/men\/mens-trail-running-shoes\/ is explicit, feature-oriented and can be reused in internationalisation (\/en\/mens-trail-running-shoes\/).
\nAvoid parameter chains ?id=129&sort=4<\/code> - they dilute relevance and undermine social sharing.
\nThe URL rewriting carried out by IKEA in 2019 (deletion of doubled \/en\/ and ?storeId=... parameter) has reduced by 30 %
\nthe rate of pages excluded from the crawl.\n<\/p>\nTop of Category content: between editorial and conversion<\/h3>\n
\nThe dilemma is well known: too much text is detrimental to the user experience; too little and Google struggles to understand.
\nThe modular approach resolves this conflict:
\n1) a succinct intro block above the listing (less than 120 words) to reassure you about the expertise;
\n2) an accordion or Tips tab under the fold (400 - 600 words) which targets related informational queries.
\nAt La Redoute, this content has been enriched with more clearly defined \"See\" anchors <h2><\/code> dynamic,
\nreducing pogo-sticking by 12 %.\n<\/p>\nPagination, facets and filters<\/h3>\n
\nFilters (size, colour, brand) generate thousands of combinations; without control, they create duplicate content.
\nThe cleanest technical option is to index only those facets that are in high demand (volume > 500 searches\/month).
\nand noindex,follow<\/code> the others. Zalando applies this principle: the red facet is indexable,
\nbut rust isn't. Combined with infinite scroll pagination based on the History API,
\nThis system preserves the discoverability and performance of Core Web Vitals.\n<\/p>\n<\/p>\n
On-Page Optimisation of Product Pages<\/h2>\nConversion-oriented Title and Meta Description tags<\/h3>\n
\nThe Title tag must combine \"keyword\", \"model\" and \"value proposition\".
\nExample : Salomon X Ultra 3 GTX Women 37 \u2153 - Waterproof hiking boots | 24h delivery.
\nA\/B tests carried out by Cdiscount on 5,000 listings showed that the mention of 24-hour delivery in Title increased CTR by 4.7 %.
\nThe meta description, while not ranking, has a strong influence on SERP traffic:
\nTake advantage of -15 % with the code TREK15. Free 30-day returns.
\nAccording to Sistrix, a CTR on mobile moving from 3 % to 4 % is often equivalent to an organic \"gain\" of two positions in visibility.\n<\/p>\n
Schema.org structured data Product<\/h3>\n
\nEnhanced snippets (price, stock, reviews) boost the SERP surface area occupied.
\nHowever, Google requires consistency between schema.org\/Offer<\/code> and visible content.
\nIn 2022, Adidas suffered a manual penalty Misleading notices for displaying 5\u2605
\non a product that no longer had any reviews. Moral: feed the tagging directly via the internal API (stock, promotional price, average rating).
\nand schedule an automated weekly test with the Search Console Product Improvement Report.\n<\/p>\nUnique content and product storytelling<\/h3>\n
\nCopying the supplier description is no longer acceptable.
\nBacklinko has shown that content produced > 300 words generates 53 % more backlinks than content < 100 words.
\nFrench retailer Snowleader is writing a Freeride vibe paragraph telling the story of each brand.
\nResult: +28 % SEO impressions on their Jones Snowboards listings in winter 2022.
\nStorytelling also nurtures emotional connection, which is indirectly correlated with the conversion rate (CRO).\n<\/p>\n
Optimised images and videos<\/h3>\n
\nWebP images, named salomon-x-ultra-3-gtx-femme.jpg, compressed to 100 Kb,
\nand accompanied by attributes alt<\/code> improve visibility in Google Images.
\nA study by SEMrush (2023) indicates that 38 % of e-commerce searches now go through the images tab.
\nThe addition of a 360\u00b0 video hosted on a CDN and pre-loaded (<\/code>)
\nhas boosted the average time on page by 15 % at Fnac.
\nMore importantly: the tag loading=\"lazy\"<\/code> on off-screen images speeds up Largest Contentful Paint (LCP) - Core Web Vitals criterion.\n<\/p>\nDynamic stock, prices and availability<\/h3>\n
\nA product that is out of stock for months ruins the budget crawl.
\nThe giants (Amazon, eBay) redirect visitors in 302 to the category or to an equivalent.
\nFor smaller sites, automatically recommend three alternatives (similar high-margin products)
\nreduces the SEO bounce rate. The in-stock monitor Python script coupled with the GSC API
\nallows noindex<\/code> records without stock in order to preserve the quality of the indexing.\n<\/p>\n<\/p>\n
Internal linking and PageRank liquefaction<\/h2>\n
\nInternal linking refers to the art of distributing PageRank, but also semantic context.
\nSuggesting a They also bought module was primarily aimed at achieving an average shopping basket;
\nit proves to be an SEO asset. According to a Botify analysis of 25 fashion sites,
\nproduct sheets with at least five contextualised internal links generate 20 % additional organic sessions.
\nTo go further, mini-clusters (category buying guide products)
\nin the form of a contextualised footer reinforce the thematic density.
\nThe result at Boulanger: the Coffee Bean Machines cluster has doubled its traffic YoY 2022\/2023 ;
\nGoogle detects a topic authority in the middle of a roll-out.\n<\/p>\n
<\/p>\n
Technical SEO and Core Web Vitals: performance as a lever<\/h2>\n
\nIn e-commerce, every 100 ms of delay is detrimental to conversion (Akamai data).
\nSince Web Vitals, Google has combined speed and ranking.
\nLighthouse recommends an LCP < 2.5 s and a CLS < 0.1.
\nPerformance Gates (#perfmatters) at Vercel has demonstrated that the transition from a monolithic Magento stack
\nto a React + Next.js + headless API front end reduces Time to First Byte by 800 ms.
\nAs far as images are concerned, the Cloudinary server-less solution automatically adapts the resolution to the viewport.
\nMore technical, the Critical CSS inlined and the pre-rendering (server-side rendering<\/em>) improve First Input Delay (FID) - soon Interaction to Next Paint (INP).\n<\/p>\n<\/p>\n
Internationalisation and multilingual e-commerce<\/h2>\n
\nThe tags hreflang<\/code> avoid cannibalisation between versions, but when used incorrectly they fragment authority.
\nIn 2017, ASOS deployed hreflang=\"en-us\"<\/code> on pages... UK!
\nResult: 17 % fall in US traffic until corrected.
\nToday, we recommend the x-default approach for the country selection page
\nand folder-based URLs (\/es\/, \/de\/...) to simplify GSC reporting.
\nNote that the content must remain culturally localised (EU vs US size, currencies, promotions).
\nShopify Markets automates certain rules, but requires an audit of the slugs to preserve the \"URL history\" signal.\n<\/p>\n<\/p>\n
Duplicate content: product variants, reviews and filters<\/h2>\n
\nVariants (colour, size) pose the headache of one URL per variant or one parameter?
\nGoogle recommends a canonical<\/code> to the parent version + JS management of image\/stock changes.
\nFnac uses this approach: the IPhone 14 128GB parent sheet is canonical;
\nthe purple version remains available for optional indexing if the volume of searches justifies it (iphone 14 violet).
\nAs for User Generated Content (UGC) - customer reviews - this can trigger near-duplicate if it is repeated elsewhere.
\nThe trick is to index the first 150 characters and then load the rest using Ajax, so that the main content retains its originality.\n<\/p>\n<\/p>\n
CRO and SEO: combining informational and transactional intent<\/h2>\n
\nSEO attracts, Conversion Rate Optimisation transforms.
\nBaymard studies show that adding reassurance icons (secure payment, free returns)
\ndirectly into the <\/code> increases the basket rate from 2 to 4 %.
\nLikewise, dynamic call-to-actions (Add to basket - Only 2 copies available!).
\ncan improve user responsiveness, but care must be taken not to interfere with Web Vitals signals.
\nShopify's Shop-Pay loads a third-party script; if deferred incorrectly, it will degrade your FID.\n<\/p>\n<\/p>\n
Case studies: Zalando, ManoMano, IKEA<\/h2>\n
\nZalando<\/strong> The 2020 overhaul of its categories introduced an 80-word text + an Influencers Choice carousel.
\nWith the Searchmetrics A\/B test, Zalando observed +7 average positions on 1,400 dress keywords in 3 months.
\nThe determining factor: the combination of internal mesh > lookbook guide > products.\n<\/p>\n\nManoMano<\/strong> The faceted Help with Choice 2021 project used machine learning to identify
\nhighly sought-after filters (power, blade length for chainsaws).
\nOnly 12 % facets are indexable;
\nyet this core captures 78 % of organic category traffic.
\nThe operation prevents the index from exploding: 240,000 superfluous URLs deleted.\n<\/p>\n\nIKEA<\/strong> Migrating from Ikea.com\/en to Ikea.fr required 620 301 redirect rules.
\nAn Anchor Text Recovery plan recovered 5 million historical internal backlinks.
\nThe gain: +25 % of top 3 keywords in France, coupled with less exo-netlinking (marketing budget preserved).\n<\/p>\n<\/p>\n
Measure, test, iterate: essential tools and KPIs<\/h2>\n
\nE-commerce SEO is a marathon.
\nPriority KPIs: organic sessions, click-through rate (CTR), conversion rate, average basket, revenue, as well as crawler metrics:
\nratio of indexed pages to total pages, average URL depth, orphan pages.
\nThe tools :
\n- Google Data Studio (Looker) for cross-referencing Search Console + GA4 ;
\n- Botify, OnCrawl or Screaming Frog for mesh auditing;
\n- Hotjar or Contentsquare to overlay the heatmap on SEO elements (e.g. position of editorial content on categories).
\nThe test and learn principle is applied: we isolate 10 % category URLs and change the length of the text,
\nwe observe for three weeks, we extend if the signal is positive.
\nAt Leroy Merlin, this method boosted SEO sales by 6 % in six months (SEO by Night 2022 conference).\n<\/p>\n
<\/p>\n
Anticipating the future: visual search, generative AI, voice commerce<\/h2>\n
\nGoogle Lens and Pinterest Lens are starting a revolution: images are becoming queries.
\nOptimise the attribute alt<\/code> is no longer enough; we need to enrich EXIF<\/code> and distribute dedicated image sitemaps.
\nAt the same time, generative AI (Bard, ChatGPT) is summarising product sheets in the SERPs.
\nThis means that the content must be structured, concise and differentiating if it is to remain clickable.
\nFinally, voice commerce is making headway via Alexa and Google Assistant.
\nVoice queries are long and conversational;
\nmark out the FAQ products (schema.org\/FAQPage<\/code>) maximises the chance of being read by the assistant.
\nAccording to OC&C Strategy, voice shopping will account for 40 G$ in 2024 in the USA; a non-visible e-retailer will not participate.\n<\/p>\n<\/p>\n
Express operational checklist<\/h2>\n
\n- Keyword research = mapping by intention (info \/ comm \/ transac).
\n- Silo structure + short URLs + depth < 3.
\n- Category: text 80 - 120 words top, 400 - 600 under-the-fold; prioritised facets and SEO-friendly pagination.
\n- Product: Title \u2264 60 car, USP + keyword; up-to-date Product Schema; unique 300-word content; WebP + images alt<\/code> 360\u00b0 lazy-load video.
\n- Internal link: mini-clusters + at least 5 contextual links per page.
\n- Core Web Vitals LCP < 2.5 s, CLS < 0.1, INP < 200 ms.
\n- International : hreflang<\/code> folder-based + x-default.
\n- Duplicate: canonical to parent, noindex<\/code> weak filters.
\n- Measurement: Search Console + Analytics + crawler, A\/B test 10 %.
\n- Future: image search, voice, AI; adapting content and mark-up.\n<\/p>\n
