Everyone knows that it is impossible to do something tiptoe there can be no perfect thing, with the changes of the Times, the past again the right things may become wrong, repair changes, sewing is normal, and you walk in the street, see everywhere in the excavation, because the previous planning is satisfied at the time, But now the rapid development of casual social cities has become less than the pace of today.
The same for the site is the same, no site design planners can design the site is quite perfect, they were three years ago or five years ago design planning site can not know, such as Baidu will release pomegranate algorithm, green Luo algorithm, original spark program, etc., A few years ago the site can rely on a one-sided reason to rush to Baidu home page, for example, what click on Ah, buy links ah, buy news source Ah, a lot of hair outside the chain ah, etc. may make the site key words on the first page is quite easy, but now with the Internet environment changes, the click of the invalid, news source, The sale link was punished, a large number of links are determined will be garbage links, invalid links, Baidu Implementation of these column strategy changes, so now a lot of people confused, now seems how hard, whether it is to write the original every day, or every day hair outside the chain, to make high-quality friends chain, the site ranking has always been standing still, Here to say is that a lot of people seem to forget something, despite the various efforts, but in the site, for example, in the key word layout, code, always unwilling to adjust, or as before the link depth is unreasonable, the URL structure is not standardized, the site title, description set unreasonable, anchor text flying and so on, Why, because they heard that the site is not active, changes may cause the right to drop, so that only a little results before the Ashes, according to the previous practice, home page title, we are trying to put all the key words are listed up, how much, the key words count up more than 10, But now it seems that this approach is wrong, the general argument is the home page title do not do too many key words, this will be decentralized weight, and some also in the title inside the addition of special characters, contact telephone, web site, etc., such as in the present seems to be undesirable, many people hear the standard answer is the key word density preferably within 8% , more than this density is likely to be the key word piling up, is a lot of professional website keyword density up to more than 20% also nothing, as long as the emergence of natural, not deliberately piling up, but also safe, but a lot of friends now clearly know it is wrong, but is not willing to change. Because the change is afraid of being down right.
Writing in the end: I want to say that the word with time is quite appropriate here, if you think there have been deficiencies before, some of the previous practice is wrong, then must be changed, since you have to change, it must be in the right direction, not afraid of being down right, and not necessarily down the right, now for the change on the right to drop the matter is not conclusive, is also the various rational, some people say that small change does not fall right, and some said as long as not frequent changes are all right, some people say to change will be down right, backward said even if the right to fall that can never fall right, after a short period of pain is bound to usher in the Sun,
