The question isn't "How the hell do I get rid of 2500 exact domain links?", it's "How the hell do I make this look organic?"
Rough ratio (of course very rough ratio, every site should be treated on a case-by-case basis with measured results if you're a real professional)
The answer to to build more backlinks, with decent velocity over say a 6 week period, to correct the ratio of backlinks on the website.
• 50-50 d0-follow/ nofollow ratio
• Exact anchor variation < 30%
â—˜ This means, building more backlinks that are LSI, generic, or just long sentence anchors like "
wrote an article for keyword anchor text that was really interesting that you should check out"
If you want some cheap BSTs for sheer volume to help balance it out, here's what I have in my Bookmarks
Blackhatlinks.com - Best Comment Blast Service - High PR / Low OBL - Ultra fast - High Volume comments, cheap and you can vary the URL/Keywords to super LSI terms which I what I would advise
Cheapest Wiki links from just $3 - High Volume and affordable Wiki posting. Again, use heavy LSI kw variation.
▲▲▲ Best Link Pyramid Service ✔ 3 Tiers - 6 Platforms ✔ 5975+ Unique Backlinks ✔ Only $5 - Super high volume Pyramid offering.
Again, my advice is to gradually increase the volume of backlinks to balance out the ratio of links, most likely in concurrency with high quality Tier 0/Tier 1 link building. Don't use the disavow tool, that's showing your hand to Google.
