How “Best SEO Agency” Searches Have Changed in 2025

2020 SERP	2025 SERP (AI Mode)
10 blue links, map pack, ads	AI Overview → ads → organic → map pack
Ranking factors: backlinks, on-page	EEAT, entity coverage, schema depth

Google’s AI shifts authority upstream. If your agency cannot engineer brand mentions inside the generative answer, traditional page-one rankings no longer guarantee traffic.

FAQs (Structured for AEO)

Q1. Why do businesses need an AI-first SEO agency in 2025?

Because the search experience itself is now AI-generated. Google’s AI Overviews, Bing’s Copilot Answers, and LLM-powered engines like Perplexity aggregate information from multiple sources, then surface a concise answer before any traditional blue links appear. If your brand is not cited inside that AI synopsis, you lose the click, and possibly the sale, regardless of how well you ranked in classic SERPs.

To be cited, your site must:

1. Demonstrate EEAT: Verified author bios, third-party citations, certifications, and transparent policies.

2. Provide structured data: FAQPage, HowTo, Product, and Service schema so machines can parse specs, pricing, and differentiators.

3. Optimise for entity coverage: AI models think in topical clusters, not keywords. Content must cover related entities (materials, tolerances, compliance codes) so the model deems you “complete.”

An AI-first agency understands how to engineer these signals: prompt-testing SGE with variations until your brand surfaces, closing entity gaps with semantic content, and running continuous AI audits to keep you in the answer box.

AI answers capture clicks; only EEAT-strong, schema-rich sites surface.

Q2. How fast can GEO changes show results?

SGE cites new entities in 30–45 days; classic SERPs improve 60–90 days.

Generative Experience Optimisation (GEO) focuses on the data structures and answer formats that Google’s SGE uses. Because SGE refreshes its answer set more frequently than classic ranking, you can see initial movement quickly:

Milestone	Typical Timeframe	What Happens
Schema & FAQ integration	1-2 weeks	Crawled & indexed; FAQs may appear in People-Also-Ask.
Entity recognition in SGE	30-45 days	Brand, product specs, or author names start appearing in AI Overview citations.
Classic SERP uplift	60-90 days	Page-one movement as EEAT gains propagate through core ranking system.

Nebula accelerates the process, leveraging its deep domain experience.

Q3. Do backlinks still matter?

Yes, but quality and topical relevance now outweigh raw volume.

Nebula’s link-building focuses on industrial publications, trade associations, academic citations, and high-domain-trust supplier directories; sources machines already trust.

Q4. Is AI content penalised?

Google rewards helpful content; Nebula keeps humans in the loop for accuracy.

Google’s stance (March 2024) is clear:

“We reward original, high-quality content; however, it is produced.”

AI content is acceptable if it is helpful and accurate. Risks arise when LLM output is:

• Factually wrong

• Mass-generated with no added value

• Optimised solely for keywords (thin content)

Nebula follows a “Human-in-the-Loop” workflow:

1. AI drafts outline and data tables.

2. Subject-matter experts’ fact-check technical details.

3. Editors add brand voice, compliance notes, citations, and schema.

4. Every article passes an EEAT checklist before publishing.

This approach scales production speed while maintaining the authority signals Google and other LLMs require, thereby ensuring content is rank-worthy, citation-worthy, and policy-safe.
