| Core function | Plerdy (plerdy.com) is a conversion rate optimisation (CRO) and SEO tool that combines user behaviour analytics with a built-in SEO checker. Core capabilities: (1) **Heatmaps** — click heatmaps, scroll heatmaps, and move heatmaps showing how users interact with specific page elements. Segment heatmaps by traffic source (organic, paid, direct), device type, and date range. (2) **Session recordings (Smart Scroll)** — video recordings of individual user sessions capturing mouse movement, clicks, scrolls, and form interactions. Filter recordings by traffic source, entry page, country, and device. (3) **SEO checker** — Plerdy's built-in SEO checker crawls the site and flags on-page issues: missing or duplicate title tags, missing meta descriptions, H1 issues, image alt text gaps, broken links, and canonical tag issues. The SEO checker integrates with Plerdy's user behaviour data to show which pages have SEO issues and low engagement simultaneously. (4) **Pop-up forms** — smart pop-up builder for lead capture, surveys, and exit-intent offers. Segment display rules by traffic source, scroll depth, time on page, and URL. (5) **Funnel analysis** — visual conversion funnel tracking showing drop-off at each step of a defined multi-step process (e.g., landing page → product page → cart → checkout → confirmation). (6) **Event tracking** — track specific UI element interactions (button clicks, form submissions, link clicks) as events without additional code — Plerdy's tracking script auto-tracks clicks by CSS selector. | A crawl-based technical SEO and AI visibility auditor. Validates all structured data against Google's Rich Results specifications with property-level error detail, measures Core Web Vitals from real CrUX field data (not Lighthouse lab estimates), detects JavaScript rendering gaps, checks robots.txt and sitemap configuration, and scores GEO signals across five AI visibility criteria. Free with no signup. No heatmaps, session recordings, or CRO features. |

| Heatmaps and user behaviour analytics | Plerdy's heatmap and session recording capabilities are its primary differentiator. Click heatmaps reveal which page elements users interact with most — identifying which CTAs get attention and which are ignored. Scroll heatmaps show how far users scroll before leaving — revealing content below the fold that most users never see. Session recordings provide qualitative context for quantitative heatmap data: watch exactly how a user navigated a page, where they hesitated, and where they abandoned. This combination — quantitative heatmap + qualitative session replay — is the core Plerdy CRO workflow for identifying conversion friction on high-traffic pages. Segmentation by traffic source (organic vs paid) allows comparing how SEO-driven users behave differently from paid traffic on the same landing pages. | No heatmaps, session recordings, or behavioural analytics. DeepSEOAnalysis audits the technical SEO implementation — structured data, crawl configuration, Core Web Vitals — not user behaviour. For understanding how organic search users interact with landing pages after arriving, Plerdy provides the behaviour data layer; DeepSEOAnalysis provides the technical readiness audit. |

| SEO checker and on-page audit | Plerdy's integrated SEO checker crawls the site and performs standard on-page checks: meta title and description coverage and length, H1 presence and duplication, image alt text gaps, broken internal links, and canonical tag presence. What makes Plerdy's SEO checker distinctive is its integration with user behaviour data: you can see which pages have both SEO issues and low engagement rates — prioritising fixes where technical gaps and user experience problems overlap. The SEO checker also tracks changes over time (comparing crawl snapshots) to monitor whether fixes have been implemented. | Technical audit at greater depth than Plerdy's SEO checker: property-level JSON-LD validation with corrected markup (detecting exactly which required property is missing in Article, FAQPage, Product, LocalBusiness structured data), real CrUX field data for Core Web Vitals (actual Chrome user experience, not Lighthouse lab estimates), JavaScript rendering gap detection (content visible in rendered DOM but absent from initial HTML — a common issue Plerdy's checker doesn't detect), and AI visibility scoring across five GEO signals — free with no signup. |

| Conversion funnel and CRO analytics | Plerdy's funnel analysis maps the conversion path from landing to goal completion, showing drop-off percentage at each step and absolute visitor counts. Combined with session recordings filtered to users who dropped off at a specific funnel step, this enables qualitative diagnosis of conversion friction — seeing exactly what users do before abandoning a checkout flow or lead form. The pop-up form builder allows testing lead capture approaches without development resources. Plerdy positions itself as a complete CRO suite for marketing teams: identify the problem (heatmaps + funnel), understand the problem (session recordings), test a solution (pop-up forms + A/B testing), and measure improvement (funnel conversion rates). | No conversion funnel analysis or CRO features. If the goal is understanding and improving conversion rates on SEO landing pages, Plerdy is the right tool for that workflow. DeepSEOAnalysis identifies the technical issues that may prevent pages from ranking in the first place — structured data gaps, Core Web Vitals failures, AI visibility — which are upstream of the CRO work Plerdy enables. |
|---|
| Structured data and AI visibility | Plerdy's SEO checker detects whether structured data is present on crawled pages. It does not perform property-level validation against Google's Rich Results specifications, does not verify structured data values match visible page content, and does not score AI visibility signals (robots.txt AI crawler access, llms.txt, FAQPage JSON-LD in server-rendered HTML vs GTM-injected, question-heading ratio, content chunkability). | Full GEO score across all five AI visibility signals with property-level structured data validation: identifies specifically whether `datePublished` is missing from Article JSON-LD, whether `acceptedAnswer.text` is empty in FAQPage, whether Product `price` is formatted as a string with currency symbol rather than a numeric value — with corrected JSON-LD markup shown for each error. This depth exceeds Plerdy's SEO checker capabilities. |
|---|
| Core Web Vitals | Plerdy reports page load speed metrics (LCP, CLS, FID/INP) from Lighthouse-based lab testing integrated into the SEO checker. Lab-based Core Web Vitals provide diagnostic direction but may not reflect real-world user experience — actual CrUX field data from Chrome users visiting the live site is what Google uses for ranking, and can differ significantly from lab measurements on the same page. | Core Web Vitals from real CrUX field data — the Chrome User Experience Report aggregates actual performance data from real Chrome users visiting the page. This is what Google uses for the Page Experience ranking signal. CrUX LCP, INP, and CLS percentile values for the specific URL (or origin) are fetched and compared against Google's published Good/Needs Improvement/Poor thresholds — not a Lighthouse simulation. |
|---|
| Best fit | Plerdy is best for marketing and CRO teams that need to understand post-click user behaviour on landing pages: which page elements drive engagement, where users drop off in conversion funnels, how organic vs paid traffic behaves differently on the same pages, and what UX changes improve conversion rates. The combination of heatmaps, session recordings, and funnel analytics in one tool is particularly valuable for teams that need qualitative and quantitative CRO data without adding multiple separate tools. | Best as the technical SEO layer that precedes and informs Plerdy CRO work: ensuring pages are technically sound (correct structured data, passing Core Web Vitals, AI visibility) before investing in CRO experimentation on pages that may have ranking-limiting technical issues. Natural workflow: DeepSEOAnalysis for technical audit at site launch and after major changes → Plerdy for ongoing CRO optimisation of pages that are ranking and receiving organic traffic. |
