Why and Should You Use Both Google Ads and Bing Ads in 2025?

Using both Google Ads and Bing Ads allows you to maximize your advertising coverage and target the right audience at the right cost. Here’s how.

Google’s wide reach is great for building brand awareness and attracting a large audience, especially on mobile devices. Bing’s connection with LinkedIn enables precise targeting for B2B campaigns, allowing you to reach specific job roles (e.g., marketing managers, CEOs) and industries (e.g., SaaS, finance) at a lower cost. Using both platforms offers a complementary approach, helping you expand your reach and effectively target the right audience at the right cost.

Here’s an example. A B2B SaaS company specializing in project management software increased its qualified leads by 20% by implementing a dual-platform strategy. They used LinkedIn targeting on Bing to reach decision-makers and Google Ads for broader brand awareness. Their overall CPA decreased by 15%.

By combining both platforms, you can ensure your ads are seen by a diverse audience while also reaching highly specific segments that are more likely to convert.

Competitor Analysis on Bing Ads

While Google Ads offers a wide range of tools for competitor analysis, Bing Ads also provides valuable insights. You can analyze competitor keywords and ad copy directly within the Bing Ads interface by using the ‘Auction Insights’ report and reviewing competitor ad placements. This allows you to identify gaps in your strategy and refine your campaigns for better performance.

Conclusion

The choice between Google Ads and Bing Ads isn’t about picking a winner but about leveraging the unique strengths of each platform. Google Ads offers unparalleled reach and innovation, while Bing Ads provides cost-effective targeting and privacy-friendly solutions. By combining both, you can create a robust advertising strategy that maximizes your ROI and reaches your target audience effectively.
