The right amount means grasping the degree when adding black links. Many people try to use black links, but end up with the opposite effect, getting their site penalized. The main reason, I think, should be not controlling the quantity well! Let me give a very simple example: if your site isn't mature yet and you buy black links, usually there are people who spend a thousand yuan on links. These thousand-yuan links are basically all added within one day, some even within a few hours. According to the normal market price for black links, a thousand-yuan worth of black links would likely get at least one or two hundred sites. And these are relatively better quality ones. We can do the math: today we'll calculate less, assuming each site that adds the black link is indexed at 200. Because we all know that when people usually buy black links, in order to get more backlinks, they often ask the sellers to add whole-site links! To be honest, what's scary about black links is the whole-site links. Previously, we calculated that with a thousand yuan, you could probably buy around 200 relatively decent quality links. Currently, PR3 black links cost about three yuan each, so spending a thousand yuan would easily get you two hundred good links. Assuming each site has an index of 200 (which is quite low), generally PR3 sites have more than this number. Now we can calculate: 200 * 200 = 40,000! You see, 40,000 links appear within one day, which is forty thousand external links. Even if the search engine were developed by fools, I estimate it would still think your site is abnormal! Therefore, the result will either be penalization or a drop in ranking, etc. And my calculation just now was rather conservative! So, regarding black links, my suggestion is: without a certain level of SEO foundation and better experience, don't easily engage in black link transactions. Of course, if someone with such experience guides you in adding links, that's fine!
For the operation of black links, many SEOers still have doubts about whether black links are effective. Here, I can definitely tell you, black links are useful, and even more effective than exchanging friendly links! Why? Because black links are essentially equivalent to others giving you a one-way link! Regarding optimization, our suggestion is to make one-way links whenever possible, rather than doing reciprocal links!
Pattern, we've already talked about the appropriate amount, next, let's talk about pattern. Why should we add black links in a patterned way? Because we all know that black links are links we buy, meaning we have control over these links. Unlike regular friendly link exchanges where, no matter how skilled you are, you can exchange four or five, maybe six links a day, which should be enough. Honestly, this pattern actually revolves around the concept of moderation because we need moderation, so when adding links, we need a pattern. Those who do SEO should know that search engines have a curve-like graph for the growth of external links for each site. Normally, the external link growth of a regular site slowly increases in a parabolic shape. However, black links or purchased links usually rise linearly. Then, when your link purchase time expires and you don't renew, they remove all your links, causing your links to fall linearly again. Therefore, for such external link growth graphs, search engines will definitely pay extra attention. If your site is indeed excellent, the impact might be minimal, but after inspection, if your site is pure junk, the outcome will likely be very bad!
Because regarding friendly links, in the guidance provided by search engines to webmasters, there's one point: be cautious when setting up your friendly links! Today we won't talk about friendly links; we'll focus on black link operations! Actually, black link operations are quite simple. In four words, it's: moderation, pattern!
