One of the optimization difficulties: FLASH

Flash, if used properly, can add a lot to the site. But if improper use, not only will bring the user experience aspects of the site, but also will greatly affect the site's search engine rankings. Many netizens have to open a website, first of all to show the immediate is a pure picture introduction or Flash introduction information experience.

Flash is primarily a movie, and it also has the ability to make a Web page. We can embed links and text in Flash to create a seemingly standard Web page. However, because the data is stored on the Web site's managed server, the suffix is. In the SWF graphics file, for search engine crawling indexing program, they cannot read and record this data. Worst of all, some websites even use flash. For such a site, you can create a standard HTML page and then embed flash into the standard Web page. Flash's developer Macromedia Company is working on an updated version of the new search engine friendliness. But before the release of this new version, those sites that simply use Flash would have little chance of getting the top 10 in search engines.

Optimization difficulty two: Content management System (CMS)

Content Management System (CMS), the emergence of people to meet their own create, publish and update the site without the need to understand the requirements of technology. For web companies that need frequent updates or a large number of contributors, the CMS system can undoubtedly bring them tangible economic benefits. CMS is particularly widely used in real estate and small retail industries.

Now the CMS program has reached hundreds of many. Unfortunately, first of all, in this hundreds of different kinds of CMS programs, the search engine can really be friendly to a few. And because the type of CMS is very much, once the search engine optimizer encounters a new type of CMS that has not been encountered before, then they must first surprise learn this CMS before the site is optimized. Second, the CMS system also often for search engine optimization for individual pages in the station title and other meta logo optimization work to increase the degree of difficulty. In addition, the default values for file naming settings for many CMS systems are clumsy and often use meaningless names like "page1.htm" or "nextpage.php". It is the above three problems that make it difficult for the optimizer to optimize the website designed by the CMS system. And to a large extent, limited to optimize the hands and feet of the staff, affecting the site's overall optimization efforts, not up to the expected ranking effect.

Three key points of optimization: Frames

Web designers often use frame to implement the toolbar navigation function, a page (browser window) split into two to many active areas, and in one of the areas to place a static menu page. The static menu Page section is always the same regardless of where the user accesses the site. The advantage is that navigation is clear and reduces the amount of code because there is no need to include menu items in each content page.

The main problem that puzzles the search engine's retrieval of frames-type site Frame-set the way it was written to the source code. When we browsed a Web page designed using frames, we were actually browsing at least three files. These files are compiled together so that they appear to be a file. The first file is the frame Setup file (Frame-set). The file then calls the rest of the pages and lets them appear on the page one at a time so that it looks like a page.

When search engines crawl through the source code, they can only see the file name, but do not see the actual file or file content itself. The optimization of frames can be done through methods such as <noframes> Meta identification optimization, but these methods are not as effective as a normal HTML file that is designed appropriately.

Optimization difficulty four: Shopping system (Shopping carts)

The shopping system not only realizes the electronic Business of commerce, but also satisfies the need that people can purchase directly from the Internet. Unfortunately, most shopping system software is less friendly to search engines. For online stores, I recommend using the Apple Pie cart system, which is a shopping system with customer-acquired features. Its designer is Robert Lee, a member of the World Wide Web Consortium Internet Consortium, and a senior web developer. In designing the shopping system, Robert has taken a comprehensive look at the performance of the search engine. Of course, there are other types of shopping systems that are also friendly to search engines, but this is one of the most open shopping systems I've ever seen for search engine crawling programs.

Optimization difficulty five: Picture index page/home page

Image index page/homepage optimization processing is also very tricky. Many designers are cheerfully creating a gorgeous "cover" for the site, ignoring the textual information the search engine needs. As a result, such a design may make the site seem as highly organized and effective as its enterprise, but a purely picture-style home page is often overlooked by the search engine's crawler because there is only a picture on this page, and there is no textual content to read and record.

Graphic web designers are often accustomed to adding links to the picture, rather than providing text links so that search engines can follow up on other pages of the site, as a result of search engine retrieval program does not follow up the picture link, then the picture contains links are likely to be overlooked by search engines.

Bianhouyu: Of course, it's much more than these techniques and design methods that make SEO people feel headache. But up to now, these five are the most difficult, challenging, or even technical or design methods that the optimizer has the most difficulty in solving. At the same time, it is necessary to remind everyone again: Software designers and search engine engineers are trying to overcome this situation: to achieve regardless of the Web site design method, the search engine crawling program can be successfully traversed and recorded. But for now, web site designers should still avoid these problems in the construction of the site, because such a design requires not only a deep design skills, but also need to have a rich knowledge of search engine optimization.
