Link building for the Sudoku games website

Throughout the year, I was engaged in external promotion (link building) for a Sudoku game website in several languages (20+ languages). After analyzing the niche and competitors, I created a plan for what type of links to place (what percentage of anchors with keywords to use and how many in the form of URLs, how many dofollow links should be there, and how many nofollow).

Links were placed evenly:
40% - on those pages that started to appear in the top 30 of Google search results, to boost their positions
40% - on those pages where I would like to see positions
20% - on the homepage.

Initially, I only placed links on forums of various languages and topics (30 per month). After 5 months, we increased the number of placements to 50 per month, also adding 20 profile links from various trusted services with high DR.

Result: growth of organic traffic from 200 per month to 4000+.
Purchasing took place: 01.01.2023-01.02.2024
Average budget: 3000 UAH per month.
