The Modern Google SERP
The Google Search Engine Results Page (SERP) has evolved dramatically from its original format of ten blue links. Today's SERP is a complex, query-specific assembly of different result types — each designed to satisfy a different user intent more efficiently than traditional organic results alone.
Research from SparkToro and Rand Fishkin (2024) found that a significant proportion of Google searches now result in zero clicks — users receive their answer directly from SERP features without visiting any website. This makes understanding SERP features essential for any SEO strategy: appearing in the right features can be more valuable than ranking #1 in organic results for some queries, while for others, the presence of certain features (like AI Overviews) dramatically reduces the click potential even for top-ranking pages.

Featured Snippets
A Featured Snippet (sometimes called "Position 0") is an extracted answer box that appears above the standard organic results for certain informational queries. Google pulls a passage, table, or list from a ranking page and displays it directly in the SERP alongside the page's title, URL, and a thumbnail image.
Google selects Featured Snippet content automatically from pages already ranking in the top 10 for a query. There is no direct submission mechanism — eligibility comes from ranking well and formatting content clearly.
Three content formats earn Featured Snippets:
- Paragraph snippets — the most common type; a 40–60 word direct answer to a question. Triggered by "what is", "how does", "why is" queries. Write a clear, direct answer in the first sentence after an H2 heading that matches the query.
- List snippets — ordered or unordered lists of steps, items, or points. Triggered by "how to", "steps to", "ways to" queries. Use proper HTML
<ol>or<ul>tags with descriptive item text. - Table snippets — structured comparative or data tables. Use proper HTML
<table>elements with descriptive headers. Triggered by comparison queries or queries seeking data in tabular form.
To optimise for Featured Snippets: Target question-form queries already ranking in positions 2–10 (position 1 is rarely displaced). Structure content with the direct answer immediately after the question-form heading. Keep paragraph answers concise (under 60 words). Use Google Search Console to identify queries where you already rank but don't have the snippet.
Earning a Featured Snippet does not always increase traffic. For "Know Simple" queries where the snippet fully answers the question, many users do not click through. However, for process or how-to queries where the snippet shows only part of the answer, earning the snippet typically increases clicks. Evaluate snippet value by query type, not by snippet presence alone.
AI Overviews
AI Overviews (formerly Search Generative Experience or SGE) are AI-generated summaries that appear at the top of the SERP for a growing proportion of queries. Powered by Google's Gemini model, AI Overviews synthesise information from multiple sources into a single narrative answer, with inline citations linking to source pages.
Google rolled out AI Overviews globally in May 2024. As of 2026, they appear for a significant proportion of informational and some commercial investigation queries, particularly complex multi-part questions and queries where a synthesised answer adds more value than a list of individual links.
There is no direct mechanism to request inclusion in AI Overviews. Google selects sources based on the same E-E-A-T signals used for organic ranking — authoritative, accurate, well-structured content from trusted sources is more likely to be cited.
Impact on organic traffic: Research from multiple sources following the global rollout indicates that AI Overviews reduce clicks for navigational and simple informational queries, but can drive citation traffic to highly authoritative sources for complex queries. Pages cited within AI Overviews often receive a visible credibility signal even if direct clicks are modest.
Optimisation approach: Ensure pages are structured clearly with direct factual statements, cite authoritative sources, demonstrate E-E-A-T signals prominently (author credentials, publication dates, source citations), and use clear heading hierarchy that allows Google to identify specific answerable passages.
Google continues to adjust which queries trigger AI Overviews, how sources are cited, and how the feature interacts with organic results. Monitor Google Search Console's performance data and keep track of AI Overview prevalence for your key queries using tools or manual SERP checks. Official guidance is available at Google Search Central.
People Also Ask
People Also Ask boxes display expandable questions related to the original query. Each question, when expanded, shows a Featured Snippet-style answer extracted from a web page. PAA boxes are dynamic — expanding one question generates additional related questions, creating an infinite scroll of related queries.
Why PAA matters for SEO: PAA boxes appear in a large proportion of Google SERPs (research from Semrush and other tools suggests 40–60% of SERPs contain a PAA box). They reveal the sub-intents and adjacent questions users have around a topic — invaluable for content planning and topical authority building.
How to earn PAA positions: The same optimisation approach as Featured Snippets applies — question-form H2/H3 headings with direct, concise paragraph answers below them. PAA boxes often pull from pages that are not necessarily ranking in the top 3 for the original query, making them accessible even for pages ranking positions 4–10.
Knowledge Panels
Knowledge Panels appear on the right side of desktop SERPs (or above mobile results) for searches about specific entities — people, organisations, places, concepts. They draw data primarily from Google's Knowledge Graph, which is populated from sources including Wikipedia, Wikidata, official websites, and structured data markup.
For businesses and brands: A Business Knowledge Panel is generated when Google has enough entity signals to create one. These are different from Google Business Profiles (which power Local Pack results). A Knowledge Panel signals to Google that your brand is a recognised entity — important for E-E-A-T and brand searches.
How to build entity presence:
- Create and maintain a Wikipedia page (if eligible — Wikipedia has strict notability requirements)
- Create and maintain a Wikidata entry for your brand or person
- Use Organisation or Person schema markup on your website
- Ensure consistent NAP (Name, Address, Phone) information across all web properties
- Build brand mentions and citations on authoritative domains
- Claim your Knowledge Panel once it appears via Google's verification process
Local Pack
The Local Pack (also called the Map Pack) displays a map and typically three local business listings for queries with local intent — "near me" searches, city-qualified service queries, and implicitly local queries (e.g. "dentist", "plumber", "pizza delivery").
Local Pack results are driven by Google Business Profile (formerly Google My Business), not by website SEO alone. A business must have a verified, complete Google Business Profile to be eligible.
Local Pack ranking factors (confirmed by Google):
- Relevance — how well the business profile matches the query
- Distance — how close the business is to the searcher's location
- Prominence — how well known the business is online (reviews, citations, website authority)
To optimise for Local Pack: Complete all fields in Google Business Profile, maintain consistent NAP data across all directories, accumulate genuine customer reviews, ensure your business category is precise, and add regular posts and photos to your Business Profile.
Rich Results
Rich Results are enhanced organic listings that display additional visual elements — star ratings, pricing, availability, event dates, recipe images — directly in the SERP. They are enabled by implementing structured data (Schema.org markup) in the correct format on your web pages.
Rich Results do not improve ranking position directly, but they significantly enhance the appearance of a listing in the SERP, which typically increases click-through rates for pages that earn them.
| Schema Type | Rich Result Displayed | Typical CTR Impact |
|---|---|---|
| Review / AggregateRating | Star ratings and review count | High — visual trust signal |
| Product | Price, availability, ratings | High — purchase intent queries |
| Recipe | Image, cook time, ratings, calories | High — dominant in recipe SERPs |
| FAQPage | Expandable Q&A below main listing | Moderate — increased real estate |
| HowTo | Numbered steps with images | Moderate to high |
| Event | Date, location, availability | High for event searches |
| Article / NewsArticle | Author, publication date, publisher logo | Moderate — enables Top Stories |
| Video | Thumbnail, duration, upload date | High — visual differentiator |
| BreadcrumbList | Breadcrumb path instead of URL | Low-moderate — improves readability |
Google's Rich Results Test
Google provides a free Rich Results Test tool at search.google.com/test/rich-results that validates your structured data markup and shows which rich result types your page is eligible for. Use it after implementing any new Schema.org markup to verify it is correctly formatted before Google next crawls the page.
Shopping Results (Product Listing Ads)
Shopping results (Product Listing Ads, or PLAs) appear as a carousel of product images, prices, and merchant names at the top or right side of the SERP for product-related transactional queries. They are primarily a paid advertising feature requiring a Google Ads account and a Google Merchant Center product feed.
However, Google also shows free organic shopping results (enabled through Google Merchant Center without a paid campaign) in some SERPs. To access both paid and free shopping placements, you need: a Google Merchant Center account, a valid and optimised product feed (title, description, GTIN, price, availability), and — for paid placement — a Google Shopping campaign in Google Ads.
Shopping results dominate the SERP for high-commercial-intent product queries. For e-commerce sites, optimising product feed titles and descriptions for Shopping is often higher ROI than on-page SEO for transactional product queries.
Building a SERP Feature Strategy
Rather than attempting to win every SERP feature for every query, an effective SERP feature strategy focuses on identifying which features appear for your target queries, assessing whether those features present an opportunity or a threat to organic clicks, and prioritising effort accordingly.
Step 1 — Audit your key queries for SERP feature presence
For every priority query in your content strategy, manually check what SERP features appear. Does a Featured Snippet already exist? Is there an AI Overview? A Local Pack? This tells you both the competition and the opportunity. Google Search Console does not directly show SERP features, but third-party tools such as Semrush's Position Tracking include SERP feature tracking.
Step 2 — Prioritise features by CTR impact for your query type
Not all SERP features reduce organic clicks. Rich Results (reviews, FAQ) typically increase CTR for the page that earns them. Featured Snippets have mixed CTR impact depending on query type. AI Overviews tend to reduce clicks for simple queries but can drive citation value for complex ones. Local Pack results are additive for local businesses. Understand the click-dynamic of each feature before investing optimisation effort.
Step 3 — Match content formatting to feature requirements
Each feature has specific content format requirements. Featured Snippets require clear question-answer formatting. Rich Results require Schema.org structured data. Knowledge Panels require entity establishment. Local Pack requires a complete Google Business Profile. Map your content production and technical implementation plan to these specific requirements rather than generic "SEO optimisation."
The SERP features present for a query are one of the most reliable signals of the intent Google has assigned to it. A SERP dominated by a Featured Snippet and PAA boxes signals strong informational intent. A SERP with Shopping results signals transactional intent. A SERP with a Local Pack signals local transactional intent. Use SERP feature analysis as part of every keyword research and content planning process.
