Link profile diversification A diverse profile is more resilient than a profile based on raw power. Diversity reduces the risk of algorithmic neutralization. ### 2. Real Traffic and User Signals A link that generates traffic is more valuable than a link without visitors. User signals and brand strength are gradually taking precedence over pure link building. ### 3. Verified indexing An unindexed link provides no SEO value. The priority is Google's primary index, not the secondary index. Indexed Google ### 4. Controlled acquisition speed The acquisition speed must keep pace with brand search speed. Growth that is too rapid leads to partial or total neutralization of links. ## Our model: your links at publisher price €25k of link building managed every month for our clients. The rule is the same for everyone: you know what each link costs, and what our work costs. ### Links at publisher price Each link is re-billed to you at the price paid to the site's publisher, Linkavista platform fees included. ### Our work billed separately Strategy, site selection, anchor texts, writing and monitoring: campaign management is covered by separate fees. Link budget and agency budget are never mixed. ### Every link tracked over time An in-house tool checks every week that your links are live and indexed. A link that drops out of the index is re-submitted, a removed link is flagged. And your links stay in place if you leave. Purchases go through [Linkavista](https://linkavista.com/fr), the link building platform co-founded by our CEO: all strategies, from sponsored articles to advanced techniques, are managed in one place. ## Key KPIs ### Traffic organic Indicate the existence of real visitors. ### Google News #### Sites indexed in Google News: fast indexing, strong authority. ### Top 3 Keywords Validate the website's ability to rank ## They trusted us. #### Alain ABULAFYA Independent "Leo helped me for 4 months with the SEO for my competitive niche website on "Gambling," and I was very satisfied.
