You misunderstood my question.
I know what you mean , the content actually from various Sources. I don't think is what you mention " crap content " What we preferring here is backlink
not preferring " unique content which naturally index by google and rank faster " Backlinks as we know here also can build our own if got time but usually
we do buy backlink services to add on.
How do you know 300 links are gone? Ahrefs is telling you that? I'd still check that manually bud and see what links are going off.
I don't think you can lose 300 links so fast, you should also know that most of the links won't get indexed.
well to be frank " missing backlinks kinda nature , I does ask before same question and some members here also encounter , got one even claim he lost 1k++ backlinks over night "
OF course that depends " as some so call backlinks are Spam backlinks put it simple not Quality ones "
Next I noticed not say Expensive service = good quality back backlinks either OR cheap ones always = bad spam backlinks.
about backlinks to get index also need time, if I not wrong. I not expert on SEO this is why i does buy various SEO services. Some sellers even kind enough help me on keywords .
the important part actually is not about index here , is the backlink still there forever. later slowly get index. If I not mistaken come index is not fast . Every time in SEO take times and vary depends.
As usual , we have to test and check which providers provide good backlink services so that can buy again for long term services.
