Recently, I have been working on four keywords: used forklifts, used loaders, used road rollers, and used cranes. The targeted search engine is GOOGLE. It seems that there has been an unusual fluctuation in GOOGLE's results. The competition level regarding second-hand machinery equipment is not particularly high. However, the rankings of these four webpages on GOOGLE change very quickly. Sometimes they are on the first page, sometimes on the second page, and sometimes they can't even be found.
This situation has me worried. Originally, one of the four webpages, the used forklift page, was blocked by GOOGLE, meaning it couldn't be found in GOOGLE searches. Later, I kept adding links, even to some webpages with relatively high PR values, and after a few days, the webpage was re-indexed. Today, I checked, and the keyword "used forklift" was already on the second page, but by afternoon, it had disappeared again. When I used the SITE command to check on GOOGLE, fortunately, the landing page for used forklifts still existed. If it exists, it means there is still a possibility, and a high one at that, for it to rank higher. Because I have accumulated some resources now, although not many or especially strong resources, they are still very helpful for optimization. Therefore, I am quite confident about optimizing the keyword "used forklift" and hope it will rank higher soon.
