Ran an experiment with a Google/Bing Top 1 strategy. The goal was to figure out how much resource and budget is actually needed to push a site into the Top 3, with the ultimate goal of reaching #1 across the entire keyword set.
For the test, I used Germany, the US, and Brazil. Niche: gambling.
Strategy 1: search suggestions only, with no direct bot interaction with the website.
Basically, all bot activity ended in the SERPs, with no direct CTR manipulation.
Surprisingly, this worked well enough to push keywords into the top positions.
The funny part is that I expected this approach to require significantly fewer resources in terms of proxies and servers, since there is no need to build up and warm up profiles for direct site visits, and each action takes no more than 30 seconds.
For a small, highly focused site with 7-10 pages and 20-30 target keywords, the total cost was $1820 to move the keywords from the Top 100 into the Top 3.
All keywords reached the target positions, and it took only 1.5 days.
Strategy 2: The classic CTR manipulation approach, with direct interaction with the website and bot actions after clicking through from the SERPs.
Surprisingly, this performed both worse and slower, despite requiring roughly the same budget.
In the end, only 37% of the keywords reached the target positions.
P.S. all domains were fresh registrations with zero history and zero backlinks.
Interested to see how these results hold up over a longer period
