Some Web site visual effect design is good, but not too friendly to search engines, affecting spiders crawling and crawling, can not promote the site rankings. Ling Long Collection summed up the following 7 points of the more common disadvantage to the spider settings.

1.Flash:

It is normal to use flash to enhance page effects in smaller areas of the page, such as flash ads, icons, and so on. Similar to this small flash effect and the picture is similar, but more vivid than the picture. The proportion of flash occupies only a small portion of the HTML code, and pages with text as the main content of the page, the search engine will not be affected.

But some pages, completely is a big flash, if this, will cause spiders can not crawl any content. There are also a Web site used to open the first page of a flash title, and so read the title and then turned to the normal HTML page. Spiders cannot read flash, nor can they distinguish flash jumps. So this kind of flash is best not to appear.

2.Session ID:

Some websites, forums use session ID (conversation ID) to track user access, each user opens the site, will generate a unique session ID, added to the URL. This will create a problem, is that every time spiders come to your site, will get a new URL, but the content is exactly the same, for search engines, multiple URLs to the same content page, or multiple URL page similarity, resulting in K station.

It is often recommended that you track user access and use cookies instead of generating session IDs. or program to determine whether the visitor is a search engine or ordinary users, if it is a spider, then remove the session ID, for spiders, the session ID is meaningless, spiders will not fill in the form, and will not put the goods into the shopping cart.

3. Various jumps:

Build station to use all jump, which except 301 jump, all other jump way search engine is not supported, some black hat seo often use jump cheat users and spiders, so unless last resort, otherwise try not to use jump.

4. Frame structure:

If you don't know what a frame structure (IFRAME) is, you've avoided a setting that is not conducive to search engines. If there is such a frame structure, try not to use it, the engine spider's view of the frame structure is like flash.

5. Dynamic URL:

A dynamic URL refers to a URL that is generated by a database-driven Web site, with a question mark, an equal sign, or some parameter. For this category should be avoided, as far as possible in the spider's eyes appear different URLs to point to the same page and similar pages.

6.JavaScript Link:

Because JavaScript can produce a lot of eye-catching effects, some sites like to use JavaScript scripts to generate navigation, but the spider is also unrecognized. So avoid using JavaScript and reduce the amount of trouble.

7. Require Login to access:

Some forums are more common, need to login, have certain permissions to access the corresponding section, but this part of the plate spider is unable to crawl. Spiders cannot fill in username, password, or register.

The above summary of several more common unfavorable to the spider's settings, in the construction of the station should be vigorously avoided.
