The verdict in three sentences
A manufacturer website with an LCP of 5.8 s and an INP of 450 ms is rated 'poor' by Google on two of the three Core Web Vitals, which hurts rankings and buyer patience. For a company with 50 to 250 employees in Germany, bringing it up to standard costs 4,000 to 20,000 EUR excluding VAT including the audit, and a full migration often exceeds 20,000 EUR. Sites that turn green frequently gain 15 to 35 % organic traffic over 6 months, provided real content work follows.
Where your site stands: 2026 thresholds
Google measures Core Web Vitals on real Chrome user data, at the 75th percentile. Here are the thresholds and the typical situation of a 2019 manufacturing WordPress site.
| Metric | 'Good' threshold | 'Poor' threshold | Typical 2019 SME site | Common cause |
|---|---|---|---|---|
| LCP (main content display) | 2.5 s or less | over 4 s | 5.8 s | 3 to 8 MB homepage slider |
| INP (interaction responsiveness) | 200 ms or less | over 500 ms | 450 ms | Page builder, 30 plugins |
| CLS (visual stability) | 0.1 or less | over 0.25 | 0.18 | Cookie banner, late fonts |
| Homepage weight | under 1.5 MB | over 4 MB | 6.2 MB | Uncompressed images, videos |
| Server response (TTFB) | under 0.8 s | over 1.8 s | 1.4 s | Entry-level shared hosting |
| Third-party JavaScript requests | under 10 | over 25 | 32 | Chat, trackers, maps, embedded videos |
An INP of 450 ms is visible in practice: the product range menu or configurator lags, and the buyer assumes the site is broken.
The cost of fixing it in Berlin
Three scenarios depending on the site's condition. Excluding VAT, 2026 order-of-magnitude estimates from German agencies and freelancers.
| Scenario | Content | Budget (ex VAT) | Timeline | Typical organic gain at 6 months |
|---|---|---|---|---|
| Audit only | Field data, prioritised report | 2,000 to 5,000 EUR | 1 to 2 weeks | None without fixes |
| Targeted fixes | Images, caching, plugins, fonts, CDN | 4,000 to 15,000 EUR | 3 to 6 weeks | +15 to 25 % |
| Full migration | New technical stack, content transfer and redirects | 20,000 to 40,000 EUR | 2 to 4 months | +20 to 35 % |
| Kolonell SEO Essentiel package | Technical monitoring, monthly optimisation | 100,000 FCFA per month (about 150 EUR) | Ongoing | Depends on content |
| Kolonell SEO Growth package | Technical, content, internal linking, reports | 200,000 FCFA per month (about 300 EUR) | Ongoing | Depends on content and competition |
| Kolonell Premium rebuild | New optimised site, in-depth SEO | 2,000,000 to 3,500,000 FCFA (3,050 to 5,340 EUR) | 4 to 8 weeks | Depends on starting point |
The decision rule is simple: if more than 20 plugins are active and the theme relies on a heavy page builder, targeted fixes plateau quickly. A rebuild on a modern stack then costs less over three years than successive patches.
Afterwards, a Kolonell monthly SEO package at the Growth level, 200,000 FCFA per month (about 300 EUR), covers Core Web Vitals monitoring, technical optimisation and product page production. Over 12 months that is about 3,600 EUR, less than a single round of one-off fixes from a local agency.
What to demand in the audit report
- field data (CrUX or Search Console), not just a lab Lighthouse score;
- a list of fixes ranked by impact and effort, costed in days;
- pages that generate quote requests handled first;
- a 301 redirect plan if any URLs change, so history is not lost.
Mini case study
Need a professional website?
Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
Hypothetical illustration: Stefan, sales director of a 140 employee manufacturer of precision components in Berlin-Adlershof. His site receives 3,000 organic visits a month and generates 12 quote requests.
He funds a 3,000 EUR audit and 9,000 EUR of fixes ex VAT. LCP drops to 2.1 s and INP to 160 ms. Cautious assumption: +20 % organic traffic with a stable conversion rate, i.e. 2.4 more requests a month. With 1 in 8 signed and an average margin of 6,000 EUR per order, that is about 21,600 EUR of margin a year for 12,000 EUR invested, a payback of roughly 7 months.
FAQ
How much does a Core Web Vitals audit cost in Germany?
Between 2,000 and 5,000 EUR ex VAT depending on the number of page templates and depth of analysis. An audit with no fix budget behind it produces no gain.
Do Core Web Vitals really affect Google rankings?
Yes, as one signal among others: with equivalent content, the faster page wins. The 15 to 35 % gains observed also come from better crawling and lower bounce rates.
Do we need to leave WordPress?
Not necessarily. A clean WordPress site with fewer than 15 plugins and a light theme can reach an LCP under 2.5 s. Beyond 25 plugins and a heavy builder, migration often becomes more cost-effective.
How long before results show?
Google's field data updates on a rolling 28 day window. Allow 1 to 2 months for metrics to turn green and 3 to 6 months for the traffic effect.
Does a monthly SEO package replace the audit?
It complements it. Kolonell's Growth package at 200,000 FCFA per month keeps performance up after the fixes, so the site does not slip back into the red with every new plugin.
