The use of source code to build a station faster, less cost, more and more by the vast number of webmaster friends recognized. But many friends in the construction station to buy the source code is gone a lot of detours, the loss of deception is often the case.

Then we buy source in the end to pay attention to which aspects, how will not be fooled? How to buy a good and cheap source code?

First of all, when dealing with someone for the first time, remember not to make money directly. It is best to trade through a trusted third party, now trusted third party such as Taobao, Pat, A5 trading. In the transaction process must be carried out according to the transaction process. Taobao and Pat deal should pay attention to the other side of the Web site is not a phishing site, in A5 transactions, to identify A5 intermediary QQ number.

Second, buy the source, to provide the test case URL, here, the general test site is two domain name, some people are black people's website for you to test, that kind of general is a level domain name. Tests not only to test the foreground, but also to test the background. Detailed confirmation of each function, before the transaction of detailed testing, trading after the installation test again, to confirm the purchase of the source code is not the same as you buy before the test, confirm the payment.

Third, to pay attention to the safety of the site, now the internet to sell a lot of the source code is very cheap, there are several yuan to dozens of yuan, these in addition to DEDECMS and Imperial system, PHP outside, There are a lot of free downloads on the Internet. On Taobao merchants often explain that this source is tested, only for everyone to study research, can not be commercial and so on. This tells you that this type of source code is not directly used. He must have a security problem, the seller is generally only measured is not complete. Most of these sources are used by people with ulterior motives for downloading, and many are Complete. The reason why people download, is to let you use, so that he hung a horse to do black chain. And these security risks general sellers can not find out.

Four, pay attention to copyright. There is no problem at the beginning of this general website. Mainly in the later stage, when your website starts to profit, someone will ask you to say the copyright matter. The first two years of the Web site popular an ASP information network, there is a red version of the green version of the art is good, the function is good, you can also be free to down, of course, some people sell. Start using is no problem, but after 6 months, or about a year. Developers will find you through his pre-existing loopholes, saying that you pirated their programs. When you open the first page will pop up a JS description. Then go to their website. Then either you pay the money back or you delete the source code. That's a tangled thing. I think some friends have come across this. The free source code on the Internet is mostly from non-state people. Many companies may start to wonder if his source code has been taken, and many of these companies are spending a lot of money on web companies. They have copyright. When they find out you are using their source code, they may also find you. They can't find a denounce, but they can take you. If the other is a big company and very serious, you may also eat a lawsuit, so if you are studying and studying, it doesn't matter. If you are building a station for your own business, you should consider it carefully.

Five, we should pay attention to optimization. Now the website is many, the competition is big. Used to do a station, you can get a good ranking, but now the same keyword, the same product, the same type of Web site, simply a dime a. Before doing the station everyone only care about the function on the line, but now have to care about its optimization performance, how to let their own site in tens of thousands of of similar sites in the emergent out, how to get a good collection, good rankings, these are people have to pay attention to the problem. There are certainly a lot of factors to get a good ranking. But the most fundamental and most important is the source code and space.

Fast, stable space is the foundation of all, good structure, optimization of good code optimization is also essential.

Overall: The DIV/CSS layout is better than the Web site of the table layout; In addition to the program has not done around the word, there is no bread crumbs to navigate. There are no alt tags in the picture. are also important.

We buy the source code only notice above five points, can not be fooled, to buy the real cheap and easy to use the source code.
