Keyword rank boosting question

Hello,

I am looking to boost the ranking for a few of my keywords, I purchased an SEO package from a vendor on here and it gave me a good boost. Now my keywords rank between 50-80 position.

Now I am looking to further boost the ranks of these keywords, I want them to show up on the first page. What should my plan be? Should I purchase more SEO packages from different vendors for the same keywords? Hence more backlinking etc

Niche relevant PBN would be best bet i guess.

Yeah, try it again.Make its push to the first-page step by step manner

You can purchase more SEO packages from the marketplace. Keep updating your site with high-quality articles. Build quality PBN links and guest posts.
