Having 10 sites already ranking is a solid foundation, but GitHub Pages can be tricky. Before spending money on ads, keep in mind that GitHub has strict Terms of Service regarding commercial use and spam, so driving massive paid traffic to a .github.io subdomain can sometimes trigger a manual review and account ban. Make sure you are using custom domains for all of them first.
To answer your questions:
1. Do you need to buy ads?
Not necessarily. If you want to increase PC/desktop traffic organically for free:
Target Desktop-Intent Keywords: PC users search differently than mobile users. Focus your content on things people only do at a computer—like 'how-to' software guides, Excel/Google Sheets templates, web tools, or complex tutorial articles. Mobile traffic is usually for quick, local, or social queries.
Build a Mini-PBN: Since you have 10 separate sites ranking, cross-link them strategically. Use highly relevant anchor text from your strongest site to push your secondary sites up for higher-volume PC keywords.
2. How to buy ads if you can't buy directly?
If you do decide to run paid traffic but face payment or regional restrictions preventing you from opening direct self-serve accounts, you have a few solid options:
Rent Google Ads Agency Accounts: You can find trusted agency account providers right here on BHW. They rent out aged, fully verified Google Ads 'Invoice' accounts that bypass local restrictions. You top up the account balance using Crypto (USDT), Payoneer, or Wise, and pay them a small percentage fee (usually 3-10%) of your ad spend.
Use Crypto-Friendly Ad Networks: If Google Ads is too difficult, look into alternative networks like MGID, PropellerAds, or Coinzilla. These platforms allow you to buy targeted desktop/PC traffic and accept deposits via USDT, Bitcoin, or WebMoney without requiring strict KYC.
Buy Direct Traffic in the BHW Marketplace: Navigate to the 'Web Traffic' section of the BHW Marketplace. There are many sellers who will sell you targeted, high-quality desktop search traffic directly, allowing you to pay with alternative payment methods.
