Most Magento stores leave significant revenue on the table not because of traffic problems but because of conversion problems. At 5MS we have audited hundreds of Magento and Adobe Commerce stores. The same seven issues appear repeatedly. Fix them and the numbers move — we have seen +32% conversion rate improvement and +74% increase in completed purchases on stores that have run through this checklist properly.
To improve your Magento conversion rate, fix these seven things in order: (1) site search that returns no results or bad results, (2) product page hierarchy that buries the add-to-cart button, (3) a checkout with unnecessary steps, (4) mobile navigation that requires too many taps, (5) faceted navigation filters that do not narrow correctly, (6) page speed above three seconds on mobile, and (7) missing trust signals at point of purchase decision. Each fix has a measurable impact within 30 days of implementation.

Visitors who use site search convert at two to three times the rate of those who browse. In every Magento audit 5MS runs, site search is where we find the biggest conversion gap — not because visitors are not searching but because the search results are broken.
- Searches for product names that exist in the catalogue returning zero results because native Magento search matches on exact attribute values only
- No autocomplete or search suggestions — visitors type a partial term and get no guidance, resulting in abandonment
- Results ranked by default Magento sort rather than by commercial relevance — bestsellers, margin, stock availability
- No synonym mapping — a search for “jacket” returns no results on a store whose products are categorised as “coats”
Replace the native Magento search with Elasticsearch (included in Adobe Commerce, available via extension on Open Source) or a purpose-built solution such as Algolia, Klevu, or Searchanise. Configure synonym libraries, autocomplete, commercial ranking, and a zero-results page that never dead-ends the visitor.
5MS audit finding: on a UK B2B Magento store audited in Q1 2026, 23% of site search queries were returning zero results. Fixing synonym mapping alone increased search-to-cart conversion by 31% within four weeks without any other changes.
The default Magento product page layout is not conversion-optimised. On mobile, the add-to-cart button frequently sits below the fold after images, description, and attribute selectors. Every scroll required between arriving on the page and seeing the buy button is a conversion leak.
- Add-to-cart below the fold on mobile
- Price not prominent — same size as surrounding copy
- No delivery or stock signal near the buy button
- Button colour blending with the theme
- Sticky add-to-cart bar on mobile scroll
- Price displayed at 1.5× body text size minimum
- “In stock — ships in 2 days” adjacent to the button
- Button colour contrasting strongly with background
The Hyva theme ships with a performance-first product page layout that resolves most hierarchy problems by default. 5MS clients who migrated from Luma to Hyva saw an average 18% add-to-cart rate improvement without any custom layout work.
The native Magento checkout is two-step which is reasonable. The problem is what gets added over time: account registration gates, redundant address fields, prominent coupon code fields that send visitors away to hunt for discounts, and payment method screens that display ten options in a confusing grid.
Enable guest checkout unconditionally. Offer account creation after the order confirmation. Never require it before. This single change typically improves checkout completion by 10 to 20%.
Hide the coupon field behind a collapsed link (“Have a discount code?”) rather than displaying the input prominently. This alone reduces checkout abandonment caused by discount code hunting.
Add a postcode-based shipping estimator to the basket page. Price surprises at payment cause the highest abandonment rate of any checkout event.
Display your top two to three payment methods prominently. Fold remaining options into a “More payment options” selector. The goal is one clear, obvious payment path.
Google’s data shows bounce rate increases by 32% when page load time goes from one second to three seconds, and by 123% when it goes from one second to ten seconds. Magento on Luma with accumulated extensions frequently loads in five to eight seconds on mobile.
| Issue | Common cause | Fix |
|---|---|---|
| Slow LCP | Hero image not preloaded, served uncompressed | Add fetchpriority="high" to LCP image, serve WebP via Cloudinary or Fastly IO |
| JavaScript bloat | Every extension adds JS. Accumulated over years it becomes unmanageable. | JS audit — remove unused scripts, defer non-critical JS, bundle aggressively |
| No CDN | Static assets served from origin, no edge caching | Cloudflare or Fastly CDN. Adobe Commerce Cloud includes Fastly by default. |
| Slow TTFB | Server not warmed, no full-page cache, database queries unoptimised | Enable Varnish FPC, Redis for session and cache, review slow query log |
| Render-blocking CSS | Luma’s CSS bundle is large and loads synchronously | Migrate to Hyva theme — CSS-in-component architecture reducing stylesheet size by 90% |
The Hyva threshold: if your Magento store is on Luma and has a PageSpeed Insights mobile score below 50, the fastest path to a significant speed improvement is migrating to the Hyva theme. 5MS Hyva migrations average a mobile PageSpeed improvement from 32 to 78. The speed improvement alone pays for the migration within the first trading quarter on stores above £100k monthly revenue.
A visitor who has found the right product at the right price still needs reassurance that the transaction is safe, the delivery is reliable, and the returns policy is fair. Missing trust signals at the point of purchase decision cause significant late-stage abandonment — the most expensive kind because you have already paid for the traffic.
Secure checkout badge, free returns policy, delivery promise — these must appear directly beside or below the add-to-cart button. Not in the footer. Not on a separate trust page. At the moment of decision.
Display the average star rating and number of reviews near the top of the product page — not buried below the fold. Schema markup on reviews also earns rich result stars in Google search results, improving click-through rate before the visitor arrives.
Display the logos of accepted payment methods on the basket page and at checkout entry — not just on the payment step. Seeing familiar payment logos earlier reduces anxiety and drop-off.
“Free returns within 30 days, no questions asked — just print the label and drop at any Post Office” is better than “Free returns”. Specific, process-level copy reduces anxiety because it makes the worst-case scenario feel manageable.

- Site search is your highest-priority fix. Visitors who use search convert at two to three times the rate of browsers. If 20%+ of your search queries return zero results, fix synonyms first before anything else.
- The add-to-cart button must be above the fold on mobile. Add a sticky bottom bar for mobile product pages. Every scroll required before seeing the buy button is a conversion leak.
- Remove the account creation gate. Enable guest checkout. This is the single highest-impact checkout change available on any Magento store that still requires login before purchase.
- Page speed above three seconds on mobile is a conversion tax. If your Luma-based store scores below 50 on PageSpeed Insights mobile, a Hyva theme migration will pay for itself within the first quarter on any meaningful revenue base.
- Trust signals must sit at the point of decision. Secure checkout badges and returns policy copy in the footer do not reduce abandonment. They need to sit directly beside the add-to-cart button and at checkout entry.
5MS runs Magento CRO audits every week. We will walk through your store, identify which of these seven issues are affecting your conversion rate, and give you a prioritised fix list with estimated impact for each. No obligation.
To improve your Magento conversion rate, audit and fix these seven areas in order: (1) fix site search zero-result queries with synonym mapping and Elasticsearch; (2) restructure the product page to put price and add-to-cart above the fold with a sticky bar on mobile; (3) enable guest checkout, collapse the coupon field, and reveal shipping costs on the basket page; (4) redesign mobile navigation for maximum two taps to category with persistent search; (5) implement AJAX faceted navigation with product counts and no zero-result combinations; (6) bring mobile PageSpeed above 60 — migrate to Hyva if on Luma; (7) place trust signals, reviews, and delivery promise directly beside the add-to-cart button. 5MS achieved +32% CVR and +74% completed purchases on stores that ran through this full checklist.
