International SEO agencies: What to look for in an international SEO strategy

Here are some factors to consider when choosing the best global SEO agency for you:

1. Specialization: Try to find an agency that has already worked with companies similar to yours and that offers tailored SEO strategies for your industry. For example, there’s a big difference in how SEO campaigns and keyword research should be done for SaaS, fintech or e-commerce, especially when targeting an international market.
2. Results: Look for an agency with a proven track record in global markets or the countries and regions that interest you. Ask for case studies, testimonials and the exact results they’ve achieved for their previous clients.
3. Services: SEO services can vary and they’ll depend on your in-house team and whether you have SEO experts or a B2B copywriter. Do you need just an SEO strategy or do you need someone to actually create and optimize your content? Some global SEO agencies offer full-service SEO, others specialize in link-building or mobile optimization, and some offer both optimizing websites and creating content for you.
4. Language: If you want to build a global online presence and translate your website to different languages, look for a global SEO company that can offer localization and international search engine optimization in the languages you desire.
5. Pricing: Finally, consider your budget and whether you can afford to hire top international SEO agencies or might want to choose a smaller team with international SEO expertise. Pricing can also depend on your industry and how difficult it is to compete.

FAQs

What does an international SEO agency do?

An international SEO agency helps businesses optimize their websites to rank higher in search engines across different countries, regions, or languages. They perform international SEO audit on your website to create strategies that consider local search behaviors, cultural differences, and language preferences to help you reach global audiences.

How is international SEO different from regular SEO?

While regular SEO focuses on optimizing for a single language or region, international SEO involves adapting strategies to suit multiple countries. This may include targeting specific keywords in multiple languages, optimizing for local search engines to make the website culturally appropriate for global presence.

Is content localization necessary for international SEO?

Yes, localization is important for connecting with local target audiences in different regions. Your content marketing strategy must align with local languages, cultural nuances, and search preferences, making it more relevant and engaging for your target market.

Why is SEO so expensive?

Search engine optimization can be expensive as it requires multiple services: on-page SEO, off-page SEO, technical SEO, website maintenance and link-building. International SEO experts often charge a lot based on their years of experience and the results they can provide you.

How do I choose an SEO marketing agency?

You should look for an agency that has already helped other clients achieve the desired results, which you can check in their case studies and testimonials. Also, choose the agency that specializes in the SEO services you need (whether you need only keyword research, link-building or local SEO services) and has already worked with companies in your industry, as the best SEO practices can vary from niche to niche.
