Natural referencing in 2025-2026 is no longer guided by the same benchmarks as it was two years ago. The merging of the Helpful Content system into core updates, the replacement of FID by INP in Core Web Vitals, and the growing importance of E-E-A-T are changing the hierarchy of technical and editorial priorities. Here we detail the levers that truly matter for a successful SEO strategy, setting aside the generalities that everyone repeats.
INP and Core Web Vitals: the technical signal that most audits underestimate
Since March 12, 2024, Google has officially replaced First Input Delay (FID) with Interaction to Next Paint (INP) as the responsiveness metric in Core Web Vitals. The difference is not cosmetic: FID only measured the delay of the first interaction, while INP assesses the latency of all user interactions during the session.
In practice, a site could easily pass FID thresholds while providing a degraded experience on subsequent clicks (opening a menu, adding to cart, navigating between tabs). INP penalizes these hidden slowdowns.
We recommend prioritizing the INP audit before any content optimization. A poor INP score degrades ranking ability even on editorially strong pages. Heavy JavaScript frameworks (non-optimized React, Angular with full hydration) are the main culprits. Reducing the workload on the main thread and deferring non-critical scripts remains the most direct way to bring INP below the recommended threshold.
When relying on the SEO offered by Belgium Référencement, this type of technical audit systematically precedes keyword work, because a failing technical foundation neutralizes editorial efforts.

Helpful Content merged into core updates: adapting the editorial cycle
Google no longer publishes a separate Helpful Content Update. Since the March 2024 core update, the evaluation system for helpful content is integrated into the core of the ranking algorithm. The practical consequences are significant.
Before this merger, a site penalized by a Helpful Content Update could hope to recover during the next update of the same system, sometimes within weeks. This is no longer the case. Recovery now only occurs at the pace of core updates, which happen a few times a year.
- Content cleaning strategies (removing or no-indexing low-value pages) must be deployed ahead of an anticipated core update, not in reaction afterward.
- Monitoring in Search Console must distinguish drops related to a core update from normal daily fluctuations, to avoid correcting what is not a problem.
- An editorial plan aligned with continuous improvement cycles (quarterly audits, updating existing content, removing outdated content) becomes more cost-effective than publishing volume.
Publishing less but better, and especially updating what already exists: this algorithmic change justifies this strategic shift, not a simple editorial preference.
E-E-A-T and authority signals: structuring credibility at the page level
The acronym E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness) is not a direct ranking factor in the algorithmic sense. But Google’s quality raters use it to evaluate results, and core updates incorporate signals that are correlated with it.
We observe that pages that clearly display the author, their qualifications, and the update date perform better during core updates than anonymous content, even with equivalent content. It is not a matter of schema.org markup (although that helps), but of overall coherence.
Concrete signals to implement
A dedicated author page with biography, links to verifiable professional profiles, and a list of publications on the site. YMYL pages (health, finance, legal) are particularly scrutinized, but we see a positive effect across all sectors.
AI-generated content without visible expert review is the typical profile that loses visibility during recent core updates. Adding a layer of verifiable human expertise (proofreading, citing sources, mentioning field experience) constitutes a measurable differentiator.

SEO keyword strategy: targeting intent rather than volume
The historical reflex is to aim for high search volume queries. This approach generates direct competition with high-authority domains, and conversion rates are often low.
We recommend structuring keyword research around search intent rather than raw volume. A moderately voluminous transactional or navigational query converts significantly better than a generic high-volume informational query.
- Group keywords by thematic cluster, with a pillar page and related satellite content linked by internal linking.
- Prioritize queries where the SERP still displays results from domains with authority comparable to yours (analyze page 1 before writing).
- Integrate long-tail variations into H2 and H3 rather than creating a page for each variant, which dilutes domain authority.
Internal linking between pages of the same cluster sends a strong thematic signal to search engines. Each internal link should use a descriptive anchor containing the target keyword of the destination page, not a generic “click here”.
Existing content versus new content
Updating an existing well-indexed page produces faster results than publishing new content on the same topic. Google retains crawl history and accumulated popularity signals. The targeted rewriting of aging content outperforms the creation from scratch in the majority of cases we handle.
An effective SEO strategy in 2025-2026 relies on three concrete technical pillars: a performance foundation measured by INP, an editorial cycle aligned with core updates, and verifiable authority signals page by page. Content volume is no longer a competitive advantage if quality and maintenance do not follow.
