PageSpeed vs Competitors: Keyword In, App-Level Blame

PageSpeed vs Competitors: Keyword In, Ranking Pages Audited, App-Level Blame

This is the only Apify Store tool that takes a keyword in, audits the pages ranking for it, and names the apps that slow you down compared with the pages that outrank you.

Enter a keyword and your URL. We find Google's top organic pages (default 5, max 10), run Lighthouse on each of them and on your page in the same run with the same device, and return a verdict like:

Judge.me reviews costs you 410 ms of main-thread time and 180 KB, and 4 of the 5 faster pages don't load it.

The first row in the dataset is a per-keyword summary: that verdict, an Ask your developer list of the top 3 removable apps with estimated savings, and your scores versus the median of the pages that outrank you. Page rows follow, with performance / SEO / accessibility / best-practices scores, LCP, TBT, CLS, FCP, Speed Index, page weight, top fixes, and named third-party vendors.

A plain URL list mode is included for agencies and monitoring. It is not the pitch.

Failed audits, unresolved search results and empty keywords are never charged.

Who it's for

• Shopify, WooCommerce and Etsy-seller store owners: find out whether a reviews app, a pixel or a marketing script is the reason you lose to faster pages for a buying keyword.
• SEO and performance teams: stop pasting 5–10 URLs into PageSpeed Insights one by one. The ranking pages are found and audited for you.
• Agencies: one run per client keyword, with a short list you can hand to a developer.

What you get

• One summary row per keyword, first in the dataset: verdict, askYourDeveloper, your metrics vs the median of the pages that outrank you (lcpGapMs, tbtGapMs, perfGap), flagged vendors, and any failed or skipped results listed separately.
• One page row per audited URL: rank, scores (0–100), Core Web Vitals, page weight, request count, top 3 Lighthouse fixes, and named vendors (main-thread time and transfer size).
• Vendor names come from a maintained Shopify / Woo / Etsy-seller app map (Judge.me, Klaviyo, Hotjar, Meta Pixel and others) plus the open-source third-party-web dataset (MIT license, © Patrick Hulce).
• A noise guard: a vendor is flagged only when it adds at least 150 ms of main-thread time or at least 100 KB and is missing from most of the faster pages. Smaller amounts are labeled "within lab noise". The numbers are always shown.

This is lab data from one Lighthouse run per page. Scores drift from run to run. Google ranks on field data; speed is one ranking factor, not the explanation. Not affiliated with Google or Lighthouse.

Input

Field	What it does
keywords	Google keywords to compare (up to 20). This is the main mode.
yourUrl	Your page, compared with the pages that outrank it. Recommended.
topN	How many organic results to audit, 1–10. Default 5.
country	Google country edition used to find the ranking pages. Default United States.
language	Optional language code (en, de, fr…). Defaults to the country's main language.
device	mobile (default) or desktop. Every page in the run is audited with the same device.
urls	Bulk URL mode: a plain list of pages to audit, with no keyword comparison. Ignored when keywords is set. Up to 50.

{
  "keywords": ["custom t shirt printing"],
  "yourUrl": "https://www.printful.com/",
  "topN": 3,
  "country": "United States",
  "device": "mobile"
}

The prefilled input (one keyword, top 3, mobile, plus your URL) is sized to finish well inside 5 minutes.

Output

The first dataset row for each keyword is the summary. This one is from a real run on 12 Nov 2026 (America/New_York) for “custom t shirt printing” with https://www.printful.com/ as the example URL, top 3, mobile, United States (run A6r0UJgaAOyt3CKIt). Lab scores drift; a later run will not match these numbers.

{
  "type": "summary",
  "keyword": "custom t shirt printing",
  "verdict": "No single app cleared the lab-noise threshold (at least 150 ms of main-thread time or 100 KB, and missing from most faster pages). Your LCP is 4301 ms from the median of the pages that outrank you.",
  "askYourDeveloper": [],
  "yourUrl": "https://www.printful.com/",
  "yourPosition": null,
  "yourPerformance": 41,
  "medianPerformance": 50,
  "perfGap": -9,
  "yourLcpMs": 10422,
  "medianLcpMs": 6121,
  "lcpGapMs": 4301,
  "yourTbtMs": 803,
  "medianTbtMs": 846,
  "tbtGapMs": -43,
  "flaggedVendors": [],
  "failedAudits": [],
  "skippedResults": []
}

On that run Printful was not in the top 3, so all three ranking pages outranked it. Its vendors were named and labeled, but none were flagged: Google Tag Manager (35 ms, 198 KB, present on most faster pages), Riskified, Sift and CookieFirst (all within lab noise). Ranking Shopify and customizer apps were named too, including Zakeke, Code Black Belt and HulkApps.

When an app does clear the threshold and is missing from most faster pages, the verdict looks like: “Judge.me reviews costs you 410 ms of main-thread time and 180 KB, and 4 of the 5 faster pages don't load it.” That line is the shape of askYourDeveloper as well.

A page row includes position, isYours, outranksYou, url, performance, seo, lcpMs, tbtMs, cls, pageWeightKB, topFixes and vendors (each with name, mainThreadMs, transferKB, and a flagLabel on your page).

How ranking URLs are resolved

Google often wraps organic links as google.com/goto. This Actor never fetches Google (or any page) from Apify. It uses DataForSEO's standard-priority Google organic SERP, which returns the resolved landing URL. If a result is still a goto wrapper, that row is skipped, not charged, and the reason is written on the row. Breadcrumb and domain fields are not used as the audit URL, because they do not reliably include the full path of the ranking page.

Pricing

Pay per event, after Apify's start fee. Prices below are live.

Event	Price	When it is charged
Actor start	$0.005	Once per run (Apify's platform fee)
lighthouse-audit	$0.01	Each page Lighthouse successfully audited
keyword-compared	$0.02	Each keyword whose results were fetched and at least one ranking page was audited

Failed audits, unresolved results, empty keywords and summary rows are free.

A typical keyword run (top 5 ranking pages + your page) is $0.085 before Apify's share: $0.005 start + 6 × $0.01 + $0.02.

Data and licensing

Ranking pages and Lighthouse reports come from DataForSEO's licensed SERP and On-Page Lighthouse APIs. Lighthouse is Apache-2.0 open source. Vendor names also use the third-party-web dataset (MIT, © 2019 Patrick Hulce); the license is bundled in the Actor source. No personal data is collected. No Google API key is used.

Limits

• Lab data, not Chrome UX Report field data.
• One Lighthouse run per page; repeat runs will not match to the point.
• Up to 20 keywords or 50 URLs per run; at most 10 ranking pages per keyword.
• Some sites (or interstitial / bot-challenge pages) cannot be audited; those rows are free.
• Lighthouse runs on DataForSEO's lab infrastructure, not from a city-level location. The country setting applies to the Google results.
