Collect, collect the boycott that be propped up by search index, because search indexes those who prop up basically is the content message that carries highland to achieve major to the user,be, the result that if search,reachs is very much it is same information, reduced the reliability that searchs engine greatly, affected the figure that searchs engine, search engine order for better maintenance, search engine can put reduplicative information in minor position only, if discover whole station achieves blame of 80% above data to be achieved formerly, will face power be fallinged, those who remove sb's name from the rolls is dangerous, remind everybody not to want to collect data for insanity and be collected wildly so, had better edit artificially, collect some do some of major, practical content.

三、采集，采集被搜索引擎抵制，是因为搜索引擎的主要是向用户提高原创专业的内容信息，如果搜索到的结果都是很多是相同信息，就大大降低了搜索引擎的可信度，影响了搜索引擎的形象，为了更好的维护搜索引擎秩序，搜索引擎只能把重复的信息放在次要的位置，如果发现整站达到80%以上数据非原创，将面临被降权，除名的危险，所以提醒大家不要为了疯狂收集数据而疯狂采集，最好人工编辑，采些做些专业、实用的内容。
