More indexing doesn''t mean higher ranking. Data pushed to the lower-tier index, unstable crawling, and outdated content are often the real factors behind ranking and traffic.
Some sites have little indexing yet thousands of visitors; others have huge indexing but only ~1000 IPs. Why? Indexing count doesn''t strongly determine ranking; traffic depends largely on ranking. Here are details worth noting.
1. Data pushed to the lower-tier index
What is the lower-tier index? An analogy: someone openly dating one person while keeping several "backups“; if they break up, a backup gets promoted. Before gaining the official status, those backups are like the "lower-tier index." Why does data land there? Think of it as: you''re useful to me now but not what I most urgently need — which concerns site content and structure. Generally, highly original sites avoid the lower-tier index; the less you invest in operations, the more likely you land there. Some B2B sites with 7-digit data and indexing still end up in the lower tier.
2. Unstable crawling
Indexing requires spiders to crawl, and crawling isn''t one-off — many pages get crawled repeatedly. If a page is unstable, the engine may form a bad impression, visitors suffer, and ranking can''t rise. Common causes: unstable server hosting, and firewall settings to watch.
3. Content has become outdated
A webmaster once asked: my article ranked stably for ages, why did it suddenly vanish? Consider: content valuable years ago may not fit today — just like technology keeps evolving. You rely on this page, but how much effort have others put into updating? Also, for time-sensitive content, clearly note an "expiry," don''t take it for granted, to avoid penalties.
