Types of SEO: When to Use Agency vs In-House Strategies | Digitalix

Search Engine Optimization (SEO) is critical for online visibility, but its complexity often confuses beginners. This guide explains the 7 main types of SEO and helps you decide which tasks to handle in-house vs outsourcing to an agency.

1. The 7 Types of SEO Explained

1.1 On-Page SEO

On-page SEO involves optimizing individual web pages. This includes:
  • Keyword Research: Identifying terms users search for (e.g., “best SEO services Singapore”).
  • Meta Tags: Writing titles and descriptions that appear in search results.
  • Content Optimization: Using keywords naturally in headings, paragraphs, and images.
  • Internal Linking: Connecting related pages to improve navigation.
Example: A blog post about “SEO tips” would use keywords like “SEO best practices” in its first paragraph.

1.2 Off-Page SEO

Off-page SEO focuses on building authority through external signals:
  • Backlinks: Links from other websites (e.g., a news article linking to your homepage).
  • Social Signals: Shares on platforms like LinkedIn or Facebook.
  • Influencer Collaborations: Partnering with industry experts to mention your brand.
Think of backlinks as “votes of confidence” from other sites.

1.3 Technical SEO

This involves behind-the-scenes optimizations:
  • Site Speed: Ensuring pages load in under 3 seconds.
  • Mobile-Friendliness: Making sure the site works on phones.
  • Crawlability: Helping search engines index your site properly.
  • SSL Security: Using HTTPS to protect user data.
Technical SEO is like the foundation of a house—it’s invisible but critical.

1.4 Local SEO

For businesses targeting specific locations:
  • Google My Business: Claiming and optimizing your business profile.
  • Local Keywords: Using phrases like “SEO agency Singapore.”
  • Customer Reviews: Encouraging satisfied clients to leave feedback.
Example: A Singapore café might rank for “best coffee near me” through local SEO.

1.5 Ecommerce SEO

Optimizing online stores:
  • Product Page Optimization: Writing detailed descriptions with keywords.
  • Category Page SEO: Structuring URLs like /shoes/mens/ instead of /p123/.
  • User-Generated Content: Encouraging customer reviews for authenticity.
Amazon uses ecommerce SEO to rank products for terms like “wireless headphones.”

1.6 Content SEO

Creating content that ranks and engages:
  • Blog Posts: Writing articles like “10 SEO Tips for Beginners.”
  • Videos: Optimizing titles and descriptions for platforms like YouTube.
  • Infographics: Designing shareable visual content.
Content SEO answers the question: “What does my audience want to read?”

1.7 Mobile SEO

Optimizing for mobile users:
  • Responsive Design: Ensuring the site adapts to all screen sizes.
  • AMP (Accelerated Mobile Pages): Creating fast-loading versions of content.
  • Mobile-Friendly Testing: Using tools like Google’s Mobile-Friendly Test.
70% of searches now happen on mobile devices—mobile SEO is non-negotiable.

2. What Should You Outsource vs Handle In-House?

2.1 Tasks Best for Agencies

  • Technical SEO: Requires specialized tools (e.g., SEMRush) and expertise.
  • Off-Page SEO: Identifying backlinks demands outreach and industry opportunities.
  • Ecommerce SEO: Complex product structures need advanced optimization.
  • Local SEO: Managing multi-location businesses requires consistent updates.

2.2 Tasks Best for In-House Teams

  • On-Page SEO: Basic keyword insertion and meta tag updates can be done by content creators.
  • Content SEO: Internal teams understand brand voice better for blogs/videos.
  • Off-Page SEO: Building backlinks demands outreach and industry connections.
  • Mobile SEO: Simple responsive design checks can be handled by developers.

2.3 Why Choose an Agency?

  • Experience: Agencies handle diverse industries and stay updated on algorithm changes.
  • Tools: Access to premium tools like Ahrefs or SEMrush.
  • Time Savings: Free up your team to focus on core business tasks.

2.4 Why Keep Some SEO In-House?

  • Brand Knowledge: Internal teams understand your products/services better.
  • Cost Efficiency: Basic on-page tasks are cheaper to handle internally.
  • Control: Direct management of content calendars and publishing schedules.

3. SEO Trends to Watch in 2025

  • AI-Driven Content: Tools like ChatGPT will assist in content creation, but human oversight remains critical.
  • Core Web Vitals: Page speed and user experience will become even more important ranking factors.
  • Voice Search Optimization: Optimizing for natural language queries like “Find SEO services near me.”
  • Video SEO: YouTube and short-form video platforms will dominate search results.
