SEO Expert Needed to Boost Traffic

I'm seeking a proficient SEO specialist who can improve our website's visibility and increase traffic significantly over the next six months. My previous freelancer hasn't been able to deliver desired results, and I'm looking for someone who can take my targeted long-tail keyword phrases and propel us to page one of search results. I can share the report. If I receive good results I will offer additional sites. The sites are not my own sites, I assist these companies with their digital assets and web site.

Key Responsibilities:
- Optimize our website for long-tail keywords with an international focus
- Develop and implement effective SEO strategies to increase website traffic

Ideal Skills and Experience:
- Proven track record of improving website rankings through SEO
- Expertise in targeting long-tail keywords
- Experience with international SEO
- Excellent understanding of SEO tools and analytics
