Ads
Ads and embeds out of control
Ad tags, video players and social widgets can weigh more than the article content itself.
Control the quality of a site
that changes every day.
Monitor article weight, the impact of ads and embeds, technical SEO across the archive and changes after publishing. Insight organizes technical signals for editorial and implementation teams.
The Free plan covers one project — no credit card required.
A publisher site does not lose only from a lack of content.
Some editorial problems start technically — before they show up in traffic, ads or page weight.
CWV
CLS ruins reading
Late-loading ads shift the text — the reader loses their place and the page loses Core Web Vitals points.
SEO
An archive Google can’t see
Thousands of older articles with indexing problems and duplication are untapped traffic.
CO₂e
Transfer footprint without measurement
Publishers increasingly ask about transfer-related carbon estimates — hard to track without a disclosed model.
Insight modules
What can you check on a publisher site?
The modules that matter most on a publisher site — from article weight to transfer CO₂e estimates.
Core Web Vitals
LCP INP CLS
LCP, INP and CLS on the reader path — home, section, article and ads.
Performance
Core Web Vitals for article pages — with a breakdown of which resources (ads included) weigh the page down.

CometWeb Insight in action
Three situations where a publisher site gains the most from checking its technical quality.
Before ad season
Article pages ready for load
Check the impact of ads and embeds on CWV before traffic rises.
- Ad script audit
- CLS on key articles
- LCP and TTFB
Before redesign
Archive and SEO under control
Audit indexability and link structure before the template change.
- Archive crawl
- Canonicals and pagination
- Redirect map
Ecology
Site carbon footprint data
CO₂e estimate (SWDM) and green hosting — for like-for-like comparison and internal monitoring, not an ESG audit.
- CO₂e per page view
- Green hosting check
- Trend over time
Process
From a URL to a fix list.
Insight walks you through the audit step by step — without stitching results from several tools.
Paste the article or home page URL
You can check the home page, category, article, landing or any other publicly available page.
Run the analysis
Insight checks the main quality areas: performance, SEO, accessibility, security and ecology.
Get priorities
You do not need to stitch results from several tools yourself. Issues are ordered by impact and urgency.
Ship fixes and compare
After changes, run another analysis and verify whether the site actually improved.
Check home page and a representative article before the ad season.

After the audit
What can you hand to the team?
A concrete issue list for your developer, agency, newsroom or ad team — with priorities, not a raw data dump.
See Insight modulesWhich ad scripts and embeds weigh article pages down most.
Where CLS shifts content and how to fix it without turning ads off.
Which technical SEO elements may limit archive visibility.
Where accessibility barriers may appear in content and navigation.
Page transfer CO₂e estimate and green hosting status (SWDM model, not energy metering).
How the score changed after a redesign, campaign or template change.
The analysis shows which resources — including ad scripts and embeds — weigh the page down most and how that translates into metrics. Insight won’t turn ads off, but it gives you arguments for the conversation with the ad team.
You run the analysis for specific addresses — for example the home page, category pages and representative articles. The Crawl module helps review the site structure more broadly and find problem areas.
The Ecology module estimates emissions based on page weight and the SWDM model, and checks whether the hosting declares green energy. It is an estimate for comparisons and internal monitoring, not a meter reading.
Yes. Every measurement is saved in the project history, so results before and after a redesign can be compared on the same metrics. Regressions — for example in CLS — are immediately visible.
Yes. Content sites serve a very broad audience, and accessibility requirements — including the EAA — cover more and more digital services. Insight detects automatically measurable WCAG issues and flags areas for manual review.
Check your site —
article by article.
Before traffic rises or you change the template, check the technical problems that may slow the site down.
