we've been trying to grow our industrial pakaging e-commerce site for two years. tbh for the past six months we've been working with an SEO agency on a monthly budget of 28,000 TL then we made some progress on technical SEO and content but when it comes to link building, the process turned into a complete black box.
during monthly meetings, they only give us vague nubers like "acquired 15 backlinks from high-authority sites this month." When I ask for the list of URLs, the anchor texts used and the placement terms they refuse to share it, claiming its a trade secret and part of their proprietary partner network.
i'm terrified of manual or algorithmic search engine penalties for manipulative link building and how can I audit their backlinks without burnnig bridges, while still protecting our business? what concrete reports contract terms or logs should I ask for and how can I spot risky tactics before it's too late?
