What Does an SEO Specialist Do?

Estimated reading time: 9 minutes. Updated December 2025.

Ask most people what an SEO specialist does and the answers get vague quickly. Something about rankings. Keywords, probably. Maybe some technical stuff?

The role often gets reduced to "makes websites show up in search results," which is true but misses most of the picture. Search no longer happens in just one place - people look for information across traditional search engines, video platforms, social media, and forums. Unlike paid search campaigns with their centralised platforms and immediate adjustments, SEO involves ongoing work across multiple areas and formats.

Much of this work happens behind the scenes, which can make the results seem almost mysterious. But there's no mystery - just data analysis, strategic thinking, content work, and understanding how people search for information.

The role sits at the intersection of understanding search behaviour, what different platforms prioritise, and how to optimise content and presence accordingly.

This guide explains what SEO specialists actually do day-to-day. The practical work that helps businesses become visible when people search for what they offer.

 

Key Takeaways:

• Data-Driven Decision Making: SEO specialists spend significant time analysing data - from audience behaviours and competitor strategies to performance metrics and algorithm changes. In 2025, this includes understanding that search behaviour varies across platforms and that visibility doesn't always translate directly to website traffic.
• Multi-Format Content Strategy: The work extends across text, images, and video. Specialists ensure content performs well in traditional search engines while also considering how people discover information through video platforms, visual search, and social media.
• Beyond the Website: Success increasingly depends on presence and consistency across the places where people search, validate decisions, and discover brands - not just optimising a single website.

1. Data Analysis and Reporting

SEO specialists spend considerable time working with data. Tools like Google Analytics and Search Console provide crucial insights, but the work now extends to understanding how people discover businesses across different platforms and touchpoints.

This goes well beyond tracking rankings. The work involves analysing search behaviours, understanding how people find businesses, monitoring competitor strategies, and staying alert to algorithm changes. Google's multiple core updates in 2025 have been significant, though other platforms also regularly update how their search and discovery systems work.

The measurement landscape has shifted significantly. On Google alone, nearly 66% of searches now end without a click to any website. Meanwhile, younger audiences often start their searches on video or social platforms. This requires tracking brand mentions, citations, and how people move between platforms before making decisions - not just traditional traffic from a single source.

What this involves:

• Audience Insights: Understanding who's searching for services, what terms they use, and where they look. Search behaviour varies by demographic - younger audiences often start on video or social platforms, while others stick to traditional search engines.
• Competitor Analysis: Identifying where competitors show up across the search landscape and spotting opportunities.
• Performance Metrics: Tracking site speed and conversions alongside engagement across different platforms and formats.
• Algorithm Updates: Monitoring significant changes across major platforms that can impact visibility.
• Attribution and Journey Mapping: Understanding how discovery journeys fragment across multiple touchpoints before conversion.
• Goal Setting and KPIs: Establishing clear, measurable objectives that acknowledge multi-platform journeys and focus on outcomes like leads and conversions.
• Reporting: Presenting findings clearly to stakeholders, with context around how search behaviour is evolving.

 

2. Copywriting and Content Optimisation

While SEO specialists aren't traditional copywriters, they craft and refine content to perform well across search platforms. This involves understanding how different platforms prioritise content - from keyword-based search engines to recommendation algorithms on social platforms - and structuring content accordingly.

The approach to keywords has evolved significantly. Search algorithms have become sophisticated at detecting manipulation. The focus now sits on natural language that serves audiences first, regardless of where they're searching.

For Google specifically, the shift in 2025 is designing content for two distinct AI systems. AI Overviews favour tight, citable answers with precise headings. AI Mode prefers connected journeys - comprehensive content with related questions and interlinked information. Beyond Google, specialists also consider how content performs in video search, visual discovery platforms, and social feeds - each with different ranking factors.

What this involves:

• Keyword Research: Identifying valuable search terms, recognising that what people type into traditional search engines differs from how they search on video or social platforms.
• Content Structure: Creating content with clear headings and concise statements that work for traditional search while also serving visual and video discovery.
• Connected Content: Building comprehensive content with related topics linked together, anticipating follow-up queries.
• Format Adaptation: Ensuring core messages work across blog posts, video scripts, image captions, and social content - each optimised for its platform's characteristics.
• Structured Data: Adding schema markup and ensuring content metadata works across different platforms.
• AI Assistance with Oversight: Using AI tools to help with content generation while ensuring output sounds authentic and provides genuine value.

 

3. User Experience (UX) and Page Layout

Search algorithms increasingly prioritise user experience, and this principle extends beyond websites to how content performs on any platform. SEO specialists ensure websites are easy to navigate and enjoyable to use, but they also consider how content translates across mobile apps, video platforms, and social feeds.

This means adjusting page layouts, improving readability, adding strategic calls to action, and organising content thoughtfully. The work considers how pages are structured, whether they function well on mobile devices (where most browsing happens), and whether visitors can easily find what they need or take the next step.

What this involves:

• CMS Management: Creating and updating pages in content management systems while keeping both search engines and user experience in mind.
• Mobile-First Design: Ensuring content works seamlessly on mobile devices, which is how most people access both websites and social platforms.
• Improving Readability: Using formatting techniques that make content easy to digest - strategic white space, images to break up text, clear calls to action, and scannable layouts.
• Cross-Platform Experience: Considering how users move between platforms and ensuring the experience remains consistent whether they land on a website, watch a video, or interact on social media.
• Page Design: Structuring pages so important information is prominent, navigation is intuitive, and visitors can easily move through a site.

 

4. Imagery and Visual Content

Visual content has moved from supporting role to starring position. Visual search usage is up 65% year-on-year, and images are now how many products get discovered - through visual search tools, social platforms, and image-heavy shopping results.

Shopping queries on Google increasingly feature large images above the fold. Pinterest has become a search engine in its own right for many consumers. People can point their camera at products or circle items on their screen to identify and purchase them instantly.

SEO specialists ensure images work across these contexts. This includes technical optimisation for speed and accessibility, but also strategic decisions about what to show, how to present it, and how to make it discoverable through visual search.

What this involves:

• Visual Search Optimisation: Ensuring images work with visual discovery tools by using high-quality formats, clear product shots, and proper file structures.
• Platform-Specific Requirements: Understanding that different platforms have specific image specifications - aspect ratios, file sizes, and metadata requirements vary.
• Technical Optimisation: Compressing images for fast loading while maintaining quality, using modern formats, and ensuring images are properly indexed.
• Descriptive Metadata: Adding alt text, useful captions, and context that helps both search systems and people understand what images show.
• Consistency: Maintaining the same visual quality and product information across websites, shopping feeds, and business profiles.
• Strategic Visual Assets: Creating step-by-step photos, comparison shots, and demonstration content that can appear in various search results.

 

5. Video Optimisation

Video has evolved from supplementary content to a primary search format. For many audiences - particularly younger demographics - video platforms are where they search for information. People type questions into YouTube, scroll to learn, and watch videos to compare products before purchasing.

Google increasingly cites YouTube videos in search results, but video discovery extends beyond one platform. Video search and recommendations happen across multiple platforms, each with different algorithms and user behaviours.

SEO specialists treat video as a search asset, not an afterthought. This means understanding how video search works, optimising metadata for discovery, and ensuring consistent branding across platforms.

What this involves:

• Video SEO Fundamentals: Creating dedicated pages for website-hosted videos with proper structured data, fast load times, and video sitemaps.
• Metadata Optimisation: Writing titles that match search intent, creating clear descriptions, and ensuring thumbnails are recognisable and on-brand.
• Platform Strategy: Deciding where to host and publish video based on goals - understanding that different platforms serve different discovery purposes.
• Transcripts and Accessibility: Providing accurate captions that make video content searchable and accessible.
• Content Integration: Connecting video content to relevant pages, using clips and stills across different formats.
• Brand Consistency: Maintaining consistent visual style and messaging across video platforms and the website.

 

6. Strategic Planning

Every business faces different challenges and operates with different resources. SEO specialists prioritise tasks to achieve the best results within available budgets and timeframes. This isn't about being present everywhere - it's about understanding where target audiences search and focusing efforts accordingly.

In 2025, strategic planning increasingly involves rethinking what success looks like. With search behaviour varying by platform and demographic, specialists focus on outcomes - leads, conversions, brand recognition - rather than just metrics from a single source.

The approach includes creating action plans, developing content calendars, and working closely with businesses to ensure strategies align with objectives and deliver measurable impact.

What this involves:

• Platform Prioritisation: Identifying which platforms matter most for specific audiences. Not every business needs every platform.
• Action Plans: Developing tailored plans that outline priority tasks, focusing on the greatest impact within available resources.
• Content Calendars: Strategically planning when content should be published, updated, or promoted to maintain consistency.
• Success Metrics: Moving beyond traditional traffic metrics to measure business outcomes - leads, sales, brand recognition - regardless of which platform generated them.
• Journey Understanding: Recognising that people often discover brands across multiple touchpoints before converting.
• Resource Allocation: Making strategic decisions about where to invest time and budget based on business goals.

 

7. Website Architecture and Navigation

How a website is structured affects both user experience and how easily search engines can crawl and understand content. SEO specialists optimise site structure, create intuitive navigation, and link related pages strategically.

A well-organised site helps visitors find what they need and helps search engines understand what each page is about. These efforts enhance both user experience and search engine performance.

What this involves:

• Navigation Improvements: Streamlining how visitors move through a site, making it intuitive to find key information.
• Internal Linking Strategies: Connecting relevant pages within a site, guiding both search engines and visitors to discover more content.
• Site Structure Audits: Regularly reviewing site hierarchy to ensure pages are logically organised and easy to crawl.

 

8. Link Management and Building

Links remain a fundamental part of how search engines assess authority and relevance. SEO specialists repair broken links, manage redirects, and develop strategies to earn high-quality backlinks.

The approach has evolved significantly - it's no longer about quantity, but quality and relevance. These activities strengthen a website's overall link profile, improve search engine rankings, and ensure visitors don't encounter frustrating errors.

What this involves:

• Fixing Broken Links: Identifying and resolving broken links that frustrate visitors and waste SEO value.
• Managing Redirects: Setting up proper redirects when URLs change, ensuring neither visitors nor search engines hit dead ends.
• Earning Backlinks: Developing strategies to earn links from reputable websites. This might involve creating genuinely link-worthy content, building relationships, or contributing expertise to industry conversations.

 

9. Developer Collaboration

Some SEO improvements require technical implementation. SEO specialists work closely with web developers, explaining technical requirements, offering solutions, and supporting implementation.

This partnership ensures crucial elements like site speed, mobile usability, and schema markup get addressed effectively. These technical factors significantly impact search performance and often need development resources to implement properly.

What this involves:

• Technical SEO: Collaborating on improvements to site speed, mobile performance, structured data implementation, and other technical factors that affect rankings.
• Problem-Solving: Working together to troubleshoot and resolve technical issues affecting site performance or crawlability.
• Clear Communication: Explaining SEO requirements to developers in ways that make implementation smoother and ensuring recommendations are clearly understood.

 

10. Brand Trust and Off-Platform Presence

SEO specialists focus on strengthening a brand's presence across the search ecosystem - not just on the website, but wherever decisions get made and validated.

Search behaviour has evolved. Discovery is fragmented: someone might first encounter a brand on a social platform, validate it through forum discussions, watch video reviews, then search directly for the brand name. Younger audiences often start searches on video or visual platforms rather than traditional search engines.

This makes off-platform presence an important part of SEO strategy. Specialists ensure brand consistency and discoverability across the places where audiences search and validate decisions.

For businesses serving local markets like Christchurch, local SEO remains vital - Google Business Profile optimisation, consistent directory listings, and local reputation management.

What this involves:

• Brand Consistency: Maintaining the same brand name, visual identity, and core messaging across all platforms where the business appears.
• Google Business Profile management: Keeping profiles current with fresh photos, accurate hours, posts, review responses, and updated information.
• Multi-Platform Presence: Establishing presence on relevant platforms where target audiences search and discover brands.
• Forum and Community Awareness: Understanding where audiences validate decisions - forums, video comments, community discussions - and ensuring brand information is accurate in those spaces.
• Review Management: Encouraging and responding to reviews across relevant platforms.
• Local Consistency: Ensuring business name, address, and phone number are accurate across directories and platforms.
• Trust Building: Creating credibility through consistent branding, positive customer experiences, and maintaining reputation wherever the brand appears.

 

Final Thoughts

SEO work spans data analysis, content creation, technical optimisation, and strategic planning. The role requires understanding how search behaviour varies across platforms and creating strategies that work across fragmented discovery journeys.

From analysing data to crafting content in multiple formats, optimising images and video, fine-tuning technical elements, and building presence beyond just a website - being an SEO specialist means working across multiple disciplines and formats. It requires strategic thinking, creativity, and sustained effort aimed at helping businesses become discoverable wherever people search for what they offer.

The SEO landscape continues evolving. Traditional search engines remain important, but discovery has fragmented. People search on video platforms, validate decisions through forums and social media, and use visual search tools to find products. Specialists must understand how these behaviours work together in customer journeys.

Visibility increasingly means being present and recognisable across multiple touchpoints - not just earning clicks from traditional search results. The fundamentals remain consistent: understand what people are searching for and where they search, create content that genuinely helps them across multiple formats, and build authority and trust gradually through quality work.
