SEO expert presenting case studies by problem type

Cases are anonymized as experience samples, and impact is qualitative unless we have explicit approval and evidence for a specific figure.

20 visible cases
Stores · Multi‑category storeCASE 01

Filter page bloat and crawl budget drain

Problem

Filter combinations created thousands of crawlable URLs, while important commercial categories were discovered late.

Operational impact

Cleaner index and better allocation of crawl resources.

Open the diagnosis, solution method, and verification →

Diagnosis: Comparing crawl data with indexing reports confirmed that the root cause was the absence of rules defining what deserves a link and indexing.

Solution method: Classify filters into genuine demand pages, use‑case‑only views, and forbidden combinations, then adjust links and canonical URLs accordingly.

Verification: Trigger recrawling, audit URL samples, and monitor how Googlebot activity shifts toward key categories and products.

Stores · WooCommerceCASE 02

Slow product templates and plugin conflicts

Problem

Product and category pages loaded slowly and elements shifted during rendering due to many overlapping plugins.

Operational impact

More stable experience and a lower‑friction purchase journey.

Open the diagnosis, solution method, and verification →

Diagnosis: Template, network, and performance data tests separated server impact from JavaScript, images, and plugins.

Solution method: Remove duplicate functionalities, defer scripts, optimize images, and configure caching with an acceptance benchmark for each template.

Verification: Compare Core Web Vitals and test conversion and add‑to‑cart after each batch of changes.

Stores · ShopifyCASE 03

Collection pages competing for the same intent

Problem

Similar collections were targeting close variants of the same queries and swapping visibility instead of establishing one page per intent.

Operational impact

Clearer ownership of each topic and expansion without internal competition.

Open the diagnosis, solution method, and verification →

Diagnosis: A keyword, links, and headings map revealed conflicting signals being sent to multiple URLs.

Solution method: Assigning an owner page for each intent, merging weaker pages, and rewriting collections and internal links around the new structure.

Verification: Tracking queries per page and checking canonical URLs and links after publication.

Stores · ZidCASE 04

Out‑of‑stock products deleted and losing built‑up demand

Problem

Deleting unavailable products broke links and wasted signals from pages that still had demand or suitable alternatives.

Operational impact

Protect accumulated value and guide visitors to an in‑stock alternative.

Open the diagnosis, solution method, and verification →

Diagnosis: Inventory and link analysis proved the need for a different policy for temporary and permanent stockouts and for replaced products.

Solution method: Keep temporarily unavailable products with alternatives, redirect permanently unavailable ones to the closest equivalent, and clean out valueless products.

Verification: Checking HTTP status codes, redirect targets, user experience, and product visibility.

Stores · SallaCASE 05

Thin commercial categories that don’t explain why to choose them

Problem

Categories showed only a product grid with no context to differentiate them for customers or search engines.

Operational impact

Stronger, clearer commercial categories without hiding products.

Open the diagnosis, solution method, and verification →

Diagnosis: Intent and template analysis showed users needed short decision units, not long filler content.

Solution method: Adding benefits, selection criteria, and FAQs inside a template that keeps shopping simple.

Verification: Reviewing mobile experience, structured data, keyword coverage, and the path into product pages.

Technical · JavaScript platformCASE 06

Key content not visible in crawlable HTML

Problem

Users could see the page, but important links and text only appeared after interactions that crawlers might not trigger.

Operational impact

More consistent discovery and indexing of core pages.

Open the diagnosis, solution method, and verification →

Diagnosis: Comparing source code with the DOM and Google render snapshots revealed a gap between the browser experience and discoverable content.

Solution method: Moving core content and links to SSR or pre‑rendered HTML and fixing errors and metadata.

Verification: Testing HTML with JavaScript disabled, using URL Inspection, and recrawling after release.

Platforms · SaaSCASE 07

Overlap between features, solutions, and use‑case pages

Problem

Teams had created overlapping pages with no clear journey from problem to product experience.

Operational impact

A scalable structure that supports discovery and product experience.

Open the diagnosis, solution method, and verification →

Diagnosis: An entities–intent matrix exposed internal competition and gaps across decision stages.

Solution method: Defining the roles of feature, solution, and industry templates and building links and CTAs to the right next step.

Verification: Monitoring query ownership, CTA engagement, and coverage growth without duplication.

Technical · RedesignCASE 08

Migrating URLs without a complete redirect map

Problem

The new design changed URL paths, and redirects relied on an incomplete manual list.

Operational impact

Reducing the risk of losing organic assets.

Open the diagnosis, solution method, and verification →

Diagnosis: A crawl inventory plus Search Console, analytics, and backlink data uncovered valuable pages missing from the migration plan.

Solution method: A one‑to‑one redirect map based on intent, avoiding redirect chains and reviewing canonical URLs, XML sitemaps, and links.

Verification: Pre‑ and post‑launch crawls and monitoring 404s, indexing, and landing pages.

Technical · Service websiteCASE 09

Traffic drop that looks like a penalty but is actually a tracking issue

Problem

Analytics showed a drop after changing the lead form, while Google Search Console did not reflect any decline.

Operational impact

Avoiding costly decisions based on misreading the data.

Open the diagnosis, solution method, and verification →

Diagnosis: Comparing data sources and deployment logs showed that what changed was the conversion event and channel definitions, not organic visibility.

Solution method: Fixing events and attribution, documenting changes, and separating search indicators from internal performance metrics.

Verification: Form tests, DebugView, and comparing Google Search Console, GA4, and actual inquiries.

Local · Multi‑branch companyCASE 10

Inconsistent branch names and addresses across the web

Problem

Business details differed between the website, Google, and local directories, and branch pages did not clarify each location’s service area.

Operational impact

Stronger local trust signals and a clearer journey for nearby customers.

Open the diagnosis, solution method, and verification →

Diagnosis: A NAP audit and mapping each branch to its page revealed duplicates, outdated profiles, and conflicting location signals.

Solution method: Unifying the source of truth, updating profiles and directories, and improving branch pages and LocalBusiness schema.

Verification: Regular review of Maps presence, contact options, directions, and NAP consistency.

Content & entities · Medical clinicsCASE 11

Medical content with no visible review or expertise

Problem

Generic treatment pages that did not show who reviewed them, what their limits were, or how to book the service.

Operational impact

More trustworthy content without exaggerated medical claims.

Open the diagnosis, solution method, and verification →

Diagnosis: An E‑E‑A‑T and entities audit showed weak definition of doctors, reviewers, and update dates.

Solution method: A clinical review workflow, expert profile pages, appropriate sources, and connecting education content to consultations.

Verification: Logging approvals and reviewing schema, link accuracy, and CTAs after updates.

Content & entities · Law firmCASE 12

Legal services with no clear expert entity

Problem

The pages target competitive queries but don’t explain the team’s expertise or the scope of service.

Operational impact

Clearer authority and a stronger trust path for commercial searchers.

Open the diagnosis, solution method, and verification →

Diagnosis: The review revealed that lawyer profiles were disconnected from the services and articles they review.

Solution method: Linking experts to their specialties, improving firm profiles, and adding legal content review.

Verification: Auditing links, structured data, expert information consistency, and consultation request paths.

Content & entities · Travel and tourismCASE 13

Seasonal pages that expire and restart from zero every year

Problem

Creating a new URL every season diluted history and left a repetitive archive after each offer ended.

Operational impact

Retaining seasonal value and preparing earlier for the next cycle.

Open the diagnosis, solution method, and verification →

Diagnosis: Analyzing cyclical demand to separate evergreen topics from temporary offers.

Solution method: Always-on seasonal pages with continuous updates, structured archiving, and a publishing calendar before search peaks.

Verification: Monitoring discovery before the season, and the availability of offers and legacy pages.

Platforms · Logistics servicesCASE 14

Tracking and shipment-status pages entering the index

Problem

Status links and parameters generated low-value pages and could expose private information.

Operational impact

A cleaner index and lower privacy risk.

Open the diagnosis, solution method, and verification →

Diagnosis: The crawl showed that forms and links were opening unintended paths for bots.

Solution method: Restricting indexing, separating service pages from tracking, and adjusting parameters and links.

Verification: Testing permissions, robots directives, and Search Console samples.

Platforms · Classified adsCASE 15

Expired listings creating 404s or staying live with no value

Problem

When listings expired they produced errors or empty pages, while some still had demand that could be redirected.

Operational impact

Sustainable management of constantly changing inventory.

Open the diagnosis, solution method, and verification →

Diagnosis: Classifying age, demand, and alternatives showed that blanket deletion or retention was not suitable.

Solution method: Alternatives for valuable listings, 410 for those with no replacement, and blocking indexing of internal search.

Verification: Regular crawls, measuring transitions to alternatives, and monitoring soft 404s.

Platforms · Recruitment siteCASE 16

Expired jobs and unsynced JobPosting data

Problem

Job data remained active after closing, or the page was deleted with no useful destination.

Operational impact

Better compliance and a more useful experience for applicants.

Open the diagnosis, solution method, and verification →

Diagnosis: Comparing the jobs database with HTML and structured data revealed differences between system status and Google’s view.

Solution method: Syncing validThrough and status, suggesting nearby jobs, and cleaning up the XML sitemap.

Verification: Rich Results Test, crawling closed jobs, and monitoring Search Console enhancement reports.

Technical · Multilingual siteCASE 17

hreflang and canonical pointing to conflicting URLs

Problem

Language versions were sending incomplete signals, and some canonical tags pushed Google back to the primary language.

Operational impact

Cleaner language signals and a more suitable version per market.

Open the diagnosis, solution method, and verification →

Diagnosis: A bidirectional matrix exposed missing links and incorrect region codes.

Solution method: Standardizing URLs, building complete hreflang sets, and adjusting x-default and sitemaps.

Verification: Crawling the sets and monitoring Google’s chosen URL and language.

Content & entities · B2B manufacturerCASE 18

Product pages relying only on specification tables

Problem

The specs did not explain applications, selection criteria, or how to request a quote.

Operational impact

Pages that act as a sales tool and cover technical research.

Open the diagnosis, solution method, and verification →

Diagnosis: Queries and sales conversations exposed a gap between the catalog and buyers’ questions.

Solution method: Adding applications, materials, certifications, and technical FAQs, and linking products to industries.

Verification: Engineering review, tracking the brochure and quote request, and auditing Product structured data.

Content & entities · Digital brandCASE 19

Weak visibility in answers and AI-driven engines

Problem

The site did not define the entity, experts, methodology, and citable facts consistently.

Operational impact

Greater interpretability and citation potential, without guaranteeing appearance.

Open the diagnosis, solution method, and verification →

Diagnosis: The review showed dispersed naming and weak evidence and linking between author and service.

Solution method: Strengthening company, expert, methodology, and source pages, plus structured data and external consistency.

Verification: Regular question testing, documenting citations, and monitoring brand search.

Content & entities · Content and services siteCASE 20

Older pages declining despite high publishing volume

Problem

New articles kept increasing while strong pages lost freshness and links and started to overlap.

Operational impact

A smaller, higher-quality portfolio that better supports services.

Open the diagnosis, solution method, and verification →

Diagnosis: Decay analysis showed the issue was portfolio maintenance, not a lack of article count.

Solution method: Planned updating, merging and pruning, relinking, and refreshing examples and CTAs.

Verification: Before-and-after comparison, competitive review, and monitoring conversions, not just visits.
