Challenges to Market Growth
Despite the positive growth trajectory, the SEO market faces certain challenges. A significant barrier to entry, particularly for small and medium-sized enterprises (SMEs), is the high upfront cost associated with effective SEO implementation. This includes the expense of necessary tools and software, such as SurferSEO (approximately USD 89 per month), Semrush and Ahrefs (exceeding USD 130 per month), and website audit tools like Screaming Frog (over USD 250). Furthermore, the cost of hiring SEO experts or agencies can exceed USD 5,000 per month. The long-term nature of SEO strategies also contributes to this challenge, as the return on investment (ROI) is often delayed, discouraging some SMEs and start-ups from fully utilizing these services.
Impact of AI and Ranking Factors
Recent developments, such as the launch of Google’s AI Overviews in May 2024, have had a noticeable impact on SEO performance. Data suggests that 63% of SEOs observed improved rankings, traffic, and visibility following the implementation of AI Overviews. Pages ranking in the first position typically possess 3.8 times more backlinks than pages ranked second through tenth. Top-ranking pages also experience a 5% to 14.5% increase in followed backlinks from new websites each month. The age of a page also appears to correlate with ranking success; as of 2024, newer pages (under one month old) rank better for high search volume keywords, accounting for 40.82% of top-ranking pages. The following table illustrates the age of top-ranking pages:
| Position | Age of Page (days) |
|---|---|
| 1 | 1883 |
| 2 | 1738 |
| 3 | 1672 |
