Catalog pipelines, payment reconciliation, marketplace listings, auth, technical SEO. Some are written up from systems that shipped, including the parts that went wrong first. The rest are reference for decisions that keep coming up.
Freight is billed on chargeable weight, a calculated figure that depends on your box as much as your product. Here is how the calculation works, where the surprises come from, and how to dispute a weight you can prove.
7 min readIndian checkouts lose orders at five predictable points: the COD decision, a UPI option buried under card fields, a pincode check that arrives too late, an address form built for another country, and an OTP in the wrong place. What each one looks like from the buyer's side, and the fix for it.
7 min readTwo channels with completely different mechanics, one shared customer list, and a set of operational rules that decide whether either keeps working. How to think about consent, segmentation, order-status messaging and measurement without borrowing someone else's benchmark.
7 min readMerchant Center disapprovals name a feed field, but the cause is usually on the landing page. What each check compares, why GST-inclusive pricing and INR trip Indian stores, which image and identifier mistakes fail on the first crawl, and how to build the feed from the catalog export you already have.
7 min readA SKU is the one product identifier you fully control, so a careless scheme is expensive to unwind and nobody else will fix it for you. What to encode, what to leave out, and why boring sequential numbers beat clever abbreviations.
6 min readYou cannot invent one, and the cheap barcode resellers sell numbers that marketplaces increasingly refuse. What a GTIN is, where a real one comes from, and the cases where you don't need one at all.
5 min readShopify decides part of your URL structure for you, so every product and category URL on an existing store is going to move. The redirect map is the artefact that decides whether the rankings move with them.
7 min readTitles, prices and images move between Shopify and WooCommerce in an afternoon. Variants, collections, metafields and URLs do not, and the redirects have to exist before DNS changes. What maps, what has to be rebuilt, and the order to do it in.
7 min readAmazon, Flipkart, Google Shopping and your own theme each cut a title off at a different point and reward a different order of words. Where each surface truncates, what a buyer scans for, and how to keep one attribute source that generates every version.
6 min readA QR code on a parcel insert, a receipt or a shop counter is a traffic source, and it goes unmeasured when it points at the homepage with no tags. Where to send the scan, why a redirect you control beats encoding the destination, and how to make a code scan from a metre away on a cheap phone.
7 min readA returned COD parcel costs you freight in both directions, the packaging, the handling and days of stock nobody can sell. Here is where those returns come from and which lever moves each cause.
7 min readThe strongest signal that a COD order will come back is written on the shipping label, and your own delivery history for that pincode comes second. Which signals carry weight, which ones are noise or discriminatory, and why a false positive costs more than it looks.
7 min readA slow store loses orders at specific moments: the product image that has not appeared, the add-to-cart tap that does nothing for a second, the checkout that stalls on 4G. What to measure on the pages where buying happens, what to ignore, and the order in which to fix the usual causes.
7 min readA buyer decides on a product page by answering six questions: when it arrives, whether it is in stock, what happens if it is wrong, what it costs in full, what it looks like up close, and what other buyers found. How to present each answer, and what to take off the page to make room.
7 min readCampaign links get tagged in a hurry by four different people and the report comes out unreadable. Here is what each parameter is for, the failure modes that split one campaign into nine rows, and the convention worth agreeing before anything goes out.
7 min readOn a hosted platform the usual performance advice has nowhere to land. The weight comes from apps, marketing tags, theme features nobody uses and images uploaded at the wrong size, all of it running in the visitor's browser.
7 min readBackground removal, alt text, auto-tagging and upscaling each break in a different place, and marketplace image rules are mechanical enough to catch every one. What each does reliably, where it fails, and what a product alt text needs to contain.
7 min readA store that felt quick at 200 products can crawl at 20,000. The cause is usually the storage model underneath WordPress, not the server it runs on.
7 min readThe CSV importer does exactly what the file tells it, which is the problem. How variations, SKUs, images and timeouts behave, and how to make an import you can safely run twice.
7 min readPermalink bases, category indexing, product schema ownership and filtered URLs are settled early on a WooCommerce store and expensive to change once indexed. Which decisions those are, how to make them, and what an SEO plugin leaves for you to do.
7 min readA variable product that shows out of stock while its sizes have units on the shelf is a modelling mistake, not a bug. How attributes, terms and variations relate, where the SKU and the stock count belong, and the CSV shape that builds it correctly.
7 min readA language model fills any gap in a product row with a plausible material, dimension or certification, and each one becomes a return or a compliance notice. How to feed it structured attributes only, keep variants from collapsing into duplicates, and review per product line instead of per SKU.
7 min readGoogle rewrites a large share of title tags and most meta descriptions before showing them. Here's what still makes both worth doing well, and how to write ones Google is more likely to keep.
6 min readHTTPS is a confirmed ranking signal. Most security headers aren't. But a botched HTTP-to-HTTPS setup, mixed content, or a redirect chain can quietly cost you indexing and referral data.
6 min readReadable URLs are a small ranking signal and a real usability one. The bigger SEO risk is changing URLs without redirects, letting filter parameters sprawl, and baking dates into paths.
6 min readThese three get used interchangeably, and they do completely different things. Here's which one to reach for when you want a page gone from Google, and why the wrong choice usually makes it stick around.
6 min readA language-model API is another third-party dependency, except this one is non-deterministic, priced per token, and occasionally confidently wrong. Here's the checklist we'd apply before shipping one into a product that already works.
6 min readIf your integration only handles a rate limit when it gets a 429, the limit is running your architecture. Treating it as a known constraint from the start changes how you queue, schedule, and prioritise work.
6 min readA webhook endpoint that assumes each event arrives once, in order, and only once is an endpoint that corrupts data on the first busy day. Here's what a receiver actually has to handle.
6 min readThe same SKU listed on ten marketplaces will oversell the moment two of them sell the last unit before the others hear about it. Here's the small set of rules that keeps stock counts honest across channels.
7 min readAI support chatbots get pitched as a blanket solution. In practice they're excellent at a narrow band of tickets and actively harmful outside it. Here's how we scope them so they help instead of adding a layer customers have to fight through.
6 min readJSON-LD is easy to add and easy to add wrong. Here's what schema markup genuinely influences in search results, what it never touches, and the mistakes that quietly invalidate it.
6 min readA landing page that performs well with your team and a small beta group can still quietly underperform once real ad traffic hits it. Here's where that gap usually comes from, and what to check before blaming the offer.
6 min readMost technical SEO audits produce a fifty-item checklist and no clear priority. Here are the five checks that, in our experience, correlate with ranking and traffic movement, and why the rest can usually wait.
6 min readStock-exchange disclosure requirements don't map cleanly onto a generic blog or page builder. Here's how we structured an investor-relations hub for a listed manufacturer that a compliance team could actually maintain.
5 min readNot every recurring-revenue business fits Stripe Billing's assumptions cleanly. Here's how we handled tiered memberships, mid-cycle changes, and pauses for a subscription rental library on plain payment-gateway primitives.
6 min readCategory and brand filtering feels simple with ten products. At real catalog size, naive facet counting turns every filter click into a full table scan. Here's how we kept multi-facet search fast for a niche-gadget storefront.
5 min readBuilding a multi-tenant Link-in-Bio product can quickly lead to complex hosting setups. Here is how we managed multiple tiers on one shared backend.
5 min readOne-time-password login looks simple until real users start mistyping codes, hammering resend, and hitting it from three cities at once. Here's how we kept OTP sign-up fast and abuse-resistant across a multi-city launch.
5 min readLocation-based discovery doesn't require a metered maps platform for every query. Here is how we built geo-search for a multi-city rental marketplace on a fixed hosting cost.
5 min readBuilding a high-volume digital e-commerce store requires robust multi-gateway failovers and automated provider integrations. Here is how we scaled a digital game recharge platform.
5 min readA supplier API answered every request with HTTP 200. During throttling, the body came back empty. Status codes alone told us everything was fine while records quietly went missing.
7 min readProcessing real-time stock and crypto markets data feeds requires robust aggregation pipelines. Here is how we engineered a stock compliance screening engine.
5 min readIntegrating Shopify inventory with custom sales channels like Temu, Allegro, or Onbuy is best handled directly in the admin dashboard. Here is how we decoupled our core marketplace synchronization engine.
5 min readHow we structured a vendor feed of 7M+ products into a staged pipeline (ingest, enrich, categorise, distribute) so a full refresh and a four-hourly price sync could run without manual intervention.
7 min readBuilding automated identity verification engines for international compliance requires robust encryption and sandboxed processing. Here is how we built an enterprise-grade document validation engine.
