I understand your concern. It's essential to maintain the integrity of your website's metrics. To address this issue, I recommend taking the following steps:

1. Contact the Seller: Reach out to the seller on Fiverr who provided the DA increaser package. Explain your concerns and request the removal of the redirect backlinks.

2. Disavow Backlinks: In case you can't get the backlinks removed, you can use Google's Disavow Tool to inform Google that you want to disassociate your website from those unwanted backlinks. This won't affect your DA or PA immediately, but it's a good practice for long-term SEO health.

3. Monitor Metrics: Keep a close eye on your website's metrics (DA, PA) using trusted SEO tools like Moz, Ahrefs, or SEMrush. Over time, as Google re-evaluates your backlink profile, your metrics should return to their natural state.

4. Build High-Quality Backlinks: Focus on building high-quality, relevant backlinks through legitimate SEO practices to improve your website's authority naturally.

Remember that SEO takes time, and it's essential to follow ethical practices to maintain a healthy online presence.

The value of using spaces or no spaces in product category page variant keywords depends on your specific SEO strategy and the search behavior of your target audience.

Using spaces between keywords (e.g., "halal meat") can make your content more readable and user-friendly, which is important for improving the user experience on your website. It can also help search engines better understand the individual words in the keyword phrase.

On the other hand, using no spaces (e.g., "halalmeat") in variant keywords can be useful for exact match targeting, especially if users are likely to search for your products using that specific format. However, it may look less natural and be more challenging to read.

Ultimately, it's advisable to conduct keyword research and consider the preferences of your target audience when deciding whether to use spaces or not. A combination of both approaches may also be effective, depending on the context and the keywords you are targeting.
