in Linux we often use the suffix for the.Gz file, which is the GZIP format, Internet today has become very common to use a data compression format, or a file format.
, for developers, the greater the amount of code, it is not easy to update and maintenance.
1, GZIP compression format
1, website code more users to download more of the loading speed will be slower. In China, the broadband and not everyone can enjoy the 20M, each developer heart is clear, the user does not want to wait.
for text content can be compressed to 40% of original size, this transmission soon, the effect is that you click on the URL will soon after the show, of course, it will also increase the load of the server, the server is installed in the general power >
, search engines crawl speed will be great impact to the website ranking.
generally refers to a function of the WWW server installation, when someone to visit this website in the server, the server will function in web content compression after transmission to the visiting computer displayed in the browser.
, as everyone knows, the rapid development of mobile Internet, to 2G network, load the 1.7M page even need a minute.
according to the survey, "the size of the average growth of 32% in 2013, an average of 1.7M, a separate HTTP request to reach 96, to tell the truth, this is a shocking number, but this is just a mean value, half of the site will be greater than this value.
in this paper, Ma Haixiang will give you some advice, although the first three recommendations to "lose weight" is not actually, but they still can effectively speed up page loading speed.
The influence of
HTTP protocol is a kind of used to improve the performance of WEB application technology, the flow of the WEB site GZIP is often used to make the user feel faster compression speed.
gzip is the abbreviation of GNUzip, it is a free software GNU file compression program. It is Jean-loupGailly and MarkAdler with the development of the first public release was issued in October 31, 1992 February released version 0.11993 version 1.
so, what is the effect of a "page overweight" website? Specifically, the following 4 points:
2 only from the domestic Shanghai Longfeng level is low. Here refers to the low level of the overall level, that is to say, me too much, master rare. This is mainly because the domestic Internet slow development, school education can not keep up, social education is also a flicker of money, coupled with the large number of the network have a big flicker master to earn tuition, so the overall level of domestic Shanghai dragon again pulled.
please indicate the source!
3 commercial application maturity. Tend to industry, products of Shanghai Longfeng, businessmen and managers have become more and more clear
3 Shanghai dragon talent concentrated in large company, or industry intensive enterprises, the company generally is difficult to go to the master.
1 got a hard to find, Shanghai dragon master industry less and less.
Shanghai dragon industry human level:
The characteristics of
2 website business, small business website and Shanghai dragon, and medium-sized sites generally larger proportion of Shanghai dragon. Because of the large web sites do not dare, it is not necessary to do Shanghai Longfeng, and small sites can easily do a few words, and then make money, but if you imagine large and medium-sized website sites that rely on the website ranking, more difficult, if you rely on the business plan to do the classification, the content is too much, and some can not afford to do. This is my personal opinion.
1 home Shanghai Dragon technology is very low. It is clear that this is lower than the international standard, but in the master hand, concept, generally low, or can be understood as lower than the international advanced level, this is not only due to this technique is the first foreign company, is our people mentality too impetuous, from people’s education problems from cultural problems, just like most of the science and technology, Shanghai dragon industry, domestic level lower than international level.
Shanghai dragon industry application level:
so, originally intended to write a good article, but in neither fish nor fowl.
industry of Shanghai Longfeng technical level:
more than 3 black hat hat. Black links, mass, cheating, black hat Shanghai dragon should be more or stronger than the white hat Shanghai dragon, unless it is a very formal company, dare not let you. This is mainly due to love Shanghai’s technology is too weak, do not explain.
1 in love Shanghai rogue, more and more enterprises begin to pay attention to Shanghai dragon, large portal also strengthened the proportion of Shanghai Longfeng department.
to write this thing, mainly because recently wanted to write an advertisement, will use the relevant information.
2 Shanghai dragon officers lack of business experience and management ability, and strengthen the ability of technology.

many shopkeepers feel bad sales of goods, after all, now the competition has been very intense industry. However, if the owner can stand in the customer’s point of view, empathy may be able to make a better business. So, if you want a hot business, might as well to think about operating. However, it is true that there are a lot of owners want to do empathy work, but do not know how to carry out. So, how to do a good job in the work of transposition thinking?
a, the customer as a friend. When faced with a friend, you may want him to get the best interest in buying, not just goods sold, naturally combined with his actual needs to introduce goods, and pick out to his friends will accept such factors more easily.
two, seize the focus of publicity. To seize the key promotional items, that is as far as possible the use of a small amount of time, according to customer demand to quickly introduce goods selling to them, rather than praise their goods chatter without stop, it will make the customer feel bored.
three, occupy the active position. In the sales process, take the initiative, the performance of self-confidence is the basis for our successful promotion. Do not be trapped by the customer’s thinking, to be good at guiding and grasping the customer, through professional knowledge to attract customer attention.
four, seeking truth from facts. In the face of customer questions on goods and services, and not to confess, in order to be able to achieve promotion purposes, to exaggerate commodity utility, or not to face their own mistakes in the work, to avoid problems will result in the loss of credit.
five, resolve customer queries in a timely manner. The face of every customer questions should be resolved immediately, if not resolved to timely advice to others, do not let the user feel you don’t care for him and his problems, so if you would lose the customer, lose the trust, ever more efforts are wasted.
in fact, the sale of any goods are in fact the same way, in the current commercial market if you want to sell goods better, might as well. In short, every time the promotion is not only the introduction of goods, but also the process of empathy, standing on the customer’s point of view to study the problem, the owners will gain more.

today is a memorable day, my site after ten days of hard work and wait, finally in the June 11th update, update date is June 6th, but I have been very happy, at least it can be said to have a certain effect, below I will talk about the site management experience, I hope everyone can give some tips and help.
site is a new sites, recruitment websites, in the recruitment industry, the website keyword selection is very important, what is the key? Said simple keyword is user input using a search engine, can maximize the information content of general users to find the word or phrase, is summarized and centralized information. But talent network keywords have certain limitations, it is regional relations, such as our website, Zhengzhou talent network 1+1, the keyword can only be Henan talent network, 1+1 talent network, Zhengzhou talent network and so on, in the search engine optimization about SEO industry keywords, and often refers to the main content of the website core. For a search engine, your web page is mostly about what you’re talking about, and that aspect boils down to a keyword (more often than not). In order to better your web page has a good ranking, but also need to understand these concepts: keyword density and keyword stack. In some search engines, you often write the word "enter keywords", which means you are prompted to enter the keywords you want to search for.
talk about so much, to illustrate the keyword, in search engine applications to grasp certain skills,
1, accurate expression, Baidu will strictly in accordance with the query you submitted to search, therefore, query word expression accuracy is the necessary prerequisite for good search results.
two selects query words based on Web page features. Many types of web pages have some similar features.
three, query topics related and concise, the current search engine can not deal with natural language well. Therefore, when submitting a search request, you’d better refine your ideas into simple queries that relate to the content of the information you want to find.
observed through these days, I also summed up the web site keywords do not fall in the Baidu rankings should grasp the skills:
one, make good use of space, stability overrides everything.
server in the near future if there were not normal visit phenomenon? The server cannot normally access is lead to a drop in one of the most common factors, therefore, you don’t have to make any changes to the website, to manage your server, to ensure the normal access, especially in the crucial time.
two, don’t optimize for optimization. Conversion key.
internal modification can cause potential errors, including excessive optimization of a keyword, such as modifying title, meta and other tags, >
