Or run both side-by-side
Most mature search marketing strategies use both SEO and PPC. PPC provides immediate traffic and testing data while SEO builds long-term sustainable visibility. Together, they dominate more search real estate.
PPC data—which keywords convert, which ad copy resonates—informs SEO priorities. SEO success in certain keywords can reduce PPC spend. Coordinated strategies maximize overall search presence.
Each, in their own words.
SEO Agency
$3,000 - $15,000+/month for agency services
SEO agencies specialize in improving organic search visibility—helping websites rank higher in Google and other search engines without paying for placement. They optimize technical factors, content, and authority signals to earn rankings.
SEO services typically include technical audits and optimization, keyword research and strategy, content optimization and creation guidance, link building and authority development, and performance tracking.
The SEO model is an investment in owned assets. Work done today—optimized pages, earned backlinks, improved authority—continues generating traffic for months and years. Rankings, once achieved, often persist with maintenance.
SEO requires patience. Unlike paid advertising, results take time to materialize. Most SEO investments take 6-12 months to show significant ranking improvements, though the long-term ROI can be substantial.
Strengths
- No per-click costs once rankings are achieved
- Traffic continues after investment with maintenance
- Higher trust and click-through rates for organic results
- Compounds over time as authority and content grow
- Drives traffic 24/7 without daily management
Considerations
- Takes 6-12 months to see significant results
- Rankings can be affected by algorithm updates
- Requires ongoing investment to maintain and grow
- Results are not guaranteed—competition matters

PPC Agency
$2,000 - $10,000+/month agency fees + ad spend (varies widely)
PPC agencies manage paid search advertising—creating and optimizing campaigns on Google Ads, Microsoft Ads, and other platforms to drive immediate traffic from search engine results pages. They pay for each click to the client's website.
PPC services include campaign strategy and structure, keyword research and bidding, ad copy creation and testing, landing page optimization, bid management, and performance reporting.
The PPC model offers immediate results and control. Campaigns can launch quickly, target specific keywords precisely, and scale up or down based on performance. Traffic is predictable and directly tied to budget.
PPC requires ongoing investment—traffic stops when spending stops. However, the ability to test, measure, and optimize quickly makes PPC valuable for understanding market demand and driving immediate results.
Strengths
- Immediate traffic upon campaign launch
- Precise targeting and control over keywords
- Highly measurable with clear attribution
- Scalable—increase budget to increase traffic
- Excellent for testing and learning quickly
Considerations
- Ongoing ad spend required—traffic stops when budget stops
- Click costs can be high in competitive industries
- Requires continuous optimization and management
- Lower trust than organic results in some industries
