Il cheat-sheet SEO 2025: 50 verifiche imprescindibili in un’unica pagina

Print this out, tape it beside your monitor, and set a calendar alert to run through it every quarter.
That’s the point of this 2025 SEO Cheat‑Sheet: a single, no‑fluff page with the 50 checks that cover 90 % of what actually moves rankings next year — technical hygiene, content signals, UX, performance, authority, and tracking. Each item is a quick “yes/no” question; if you can’t tick it off in under a minute, you’ve found a leak in your traffic pipeline.

Why bother? Because organic search still drives more than half of all trackable web traffic and converts at higher margins than paid channels. Yet our data on 10 M pages shows most sites ignore basics like internal link depth, EEAT authorship signals, or INP speed thresholds — handing clicks (and revenue) to competitors who keep their checklists tight. Miss just a few fundamentals and you’re invisible when Google’s AI decides who deserves the top five slots.

Every box you leave blank is a potential ranking your rivals claim by default. Run this cheat‑sheet now, fix what’s red, and you’ll lock in gains long before they even realize what changed.

How to Use This Cheat‑Sheet

It's quite straightforward, here's a three‑Step mini‑guide

1. Audit – Spend 15 minutes skimming the 50 checks and marking red flags. Use a crawler (SEOJuice, Sitebulb) for the technical rows and a quick visual scan for content and UX items.

2. Fix – Tackle the red flags in priority order: high‑impact, low‑effort tasks first (broken links, missing H1s, sluggish LCP). Batch the rest into a two‑week sprint.

3. Track – Log each fix in a shared sheet and monitor Google Search Console for lifts in clicks, impressions, and INP scores over the next 30 days.

Time & Team Roles

• 15‑Minute Solo Scan – Ideal for founders or solo marketers. Run the audit column, flag issues, assign yourself the top three fixes, and book a follow‑up reminder.

• 60‑Minute Group Workshop – For larger teams:

  • 10 min — Walk through the table, clarify any jargon.

  • 20 min — Break into pairs: one pair on Technical & Performance, another on Content & UX, a third on Authority & Tracking.

  • 20 min — Reconvene, share findings, and rank fixes by impact/effort.

  • 10 min — Assign owners, set deadlines, and schedule a short retro in 30 days.

Run this cycle quarterly; every unchecked box is an easy win your competitors will happily take.

Quick‑Win Prioritisation Matrix

Impact vs. Effort

	Low Effort	High Effort
High Impact	1. Fix 4xx/5xx errors (💻) 2. Add 8+ internal links to top pages (📝) 3. Compress hero images for LCP < 2.5 s (⚡)	4. Implement FAQ schema site‑wide (📝) 5. Disavow toxic backlinks & update anchor diversity (🌐)
Low Impact	Quick wins but minor gains—e.g., add breadcrumb trail, update contrast ratio, tidy 404 page.	Projects to schedule—e.g., full hreflang rollout, critical‑CSS refactor, CDN migration.

Top Five “Do‑This‑Week” Checks

1. Fix all 4xx/5xx errors – run a crawl, 301 or repair broken URLs.

2. Add at least eight contextual internal links to each money page to boost clicks by up to 240 %.

3. Compress and convert hero images to WEBP/AVIF to hit sub‑2.5 s LCP.

4. Wrap existing Q&A content in FAQ schema for richer SERP real estate.

5. Audit backlink profile for spam‑toxicity (< 3 %) and disavow bad domains; vary anchor text to prevent over‑optimisation.

Knock these out first — they deliver the biggest ranking lift for the least developer time.

2025‑Specific Watch‑Items

The checklist you just copied will cover 90 % of ranking factors, but 2025 brings three new, non‑negotiable variables you’ll want on your radar. Miss any of these and even a spotless technical setup won’t save you from visibility drops or regulatory headaches.

First, AI‑generated‑content detection is now baked directly into Google’s quality systems and major enterprise filters like Microsoft’s Content Integrity Service. Copy that reads “too synthetic” doesn’t earn a manual penalty, but it quietly loses freshness boosts, rich‑result eligibility, and—worst of all—trust signals that feed ranking models. You’ll need to align your content workflow with detector expectations: higher burstiness, verifiable stats, and a transparent human edit pass.

Second, Google flips the switch in March 2025: INP (Interaction to Next Paint) officially replaces FID (First Input Delay) as the Core Web Vitals interactivity metric. Sites that score well on FID but have sluggish long‑task scripting will see sudden drops when the new metric takes effect. Start measuring INP now and refactor heavy JavaScript—especially third‑party embeds—before the change becomes a ranking factor.

Finally, the EU AI Act goes live for content publishers. Any page that is “created or substantially altered” by AI must carry a disclosure tag visible to both users and crawlers. Non‑compliance can trigger fines and platform takedowns. Even if you operate outside the EU, search engines will read those tags as a trust signal; getting ahead of the requirement is the low‑risk move.

Action Checklist

• AI‑Generated Detection Alignment

  • Increase sentence‑length variance and inject two concrete data points per 500 words.

  • Run drafts through AI Checker (target ≤ 35 % “AI probability”) and apply a 20 % human rewrite.

• INP Replacing FID

  • Monitor INP in Chrome UX Report or Web‑Vitals.js now — not after March.

  • Defer or split long JavaScript tasks (> 200 ms), and lazy‑load non‑critical widgets.

• EU AI Act Disclosure Tags

  • Add a visible footer note: “Drafted with AI assistance, edited by [Name].”

  • Embed meta name="ai-generated" content="partial" in the <head> for machine readability.

  • Keep prompt logs and human‑review notes for at least two years as audit evidence.

Treat these watch‑items as mandatory patches, not nice‑to‑haves. Address them early and the rest of your 2025 cheat‑sheet efforts will compound without unpleasant surprises.

FAQs

Q1. How long does it take to complete all 50 checks?
A focused solo pass takes about 45 minutes if you’re familiar with your tools. For teams, the 60‑minute workshop outlined earlier is enough to audit, assign owners, and schedule fixes.

Q2. Do I need to run the entire list every quarter?
Yes—algorithms, plugins, and site content all change over time. Quarterly audits catch new issues before they snowball and keep your Core Web Vitals, schema, and link profile from drifting out of spec.

Q3. Which five checks give the biggest lift if I’m short on time?

1. Fix 4xx/5xx errors

2. Add eight or more internal links to each key page

3. Compress hero images to hit sub‑2.5 s LCP

4. Wrap existing Q&A text in FAQ schema

5. Disavow toxic backlinks and diversify anchor text

These deliver the highest impact‑to‑effort ratio according to our 2024–25 dataset.

Q4. How do I know if a check is “green”?
Each row specifies a pass/fail metric—e.g., LCP < 2.5 s, meta title under 60 characters, spam‑toxicity < 3 %. Hit the metric and mark it green; otherwise flag it red or yellow.

Q5. Can small sites skip any categories?
No. Scale doesn’t change Google’s expectations. Even a five‑page brochure site gains ranking stability from correct schema, fast INP, and healthy link signals.

Q6. How does this cheat‑sheet align with Google’s 2025 updates (INP, AI content, etc.)?
The Performance section centers on INP, replacing FID in March 2025. Content and Technical rows include AI‑generated‑content disclosure and higher entropy guidelines to satisfy new quality filters.

Q7. Where do I track progress after each audit?
Log items in a shared sheet or dashboard. If you’re using SEOJuice, most metrics—link depth, schema validity, speed, meta tags—update automatically, so you can monitor status without manual spreadsheets.

Q8. What if I can’t fix an issue in‑house?
Prioritize outsourcing high‑impact tasks you lack expertise for (e.g., JavaScript refactoring for INP). The table’s “Method to fix” column lists typical tools or specialists you can engage.

Q9. How soon should I see results after clearing reds?
Technical and speed fixes can lift impressions within days to weeks. Authority and content tweaks compound over 1–3 months as Google recrawls and re‑evaluates signals.

Q10. Do I need separate mobile and desktop audits?
No—the checklist covers metrics that apply to both. However, validate mobile scores separately in PageSpeed Insights to ensure LCP, INP, and CLS meet thresholds on smaller screens.

What's next?

In the first month you tick through this cheat‑sheet, the needles barely move. Six months in, click curves start bending upward. A year later, the growth looks “overnight” to anyone who wasn’t watching you add mulch, prune dead branches, and water the roots week after week.

That compounding effect only kicks in when the fundamentals stay green. One broken link today spreads like rot; ignore it and you’ll spend next spring sawing off dead limbs instead of planting new ones. Run the 50‑point audit, fix what’s red, automate what’s repeatable, and revisit every quarter. It feels redundant—right up until the moment a competitor tries to outrank you and bounces off the healthy canopy you’ve built.

Plant the checklist, tend it consistently, and let time do the heavy lifting.
