Some SEO knowledge involved in web design

Since the birth of the search engine, SEO has become particularly important, through the optimization of the site to improve rankings, and thus improve the flow of the site in the early days of construction, we have to take precautions, to the SEO knowledge to consider, the author according to their own experience, wrote the following points:

1, Discard table, use div

Table made of the Web page for search engines, is not so optimized, n more nested forms, will make spiders "annoying", so, in the construction station, we should as far as possible discard table, transfer to Div, of course, not to say complete abandonment, if there is a need table is the time , but also to use, the two are combined.

2, the paragraph title should be appropriate tagging

This is a lot of friends have said that the important information in the page paragraph title with <H1>,</H1> logo, the important information with <H1>,</H1> logo out,<b><strong> The emphasis of the logo can also be used as much as possible, it should be noted that a page should have only one <H1>,</H1> label pair, but can have more than one <H1>,</H1> tag pair, too much <h1>,</ H1> tags on the word, will be search engines think your site has cheating behavior.

3, the page in the footsteps to external

CSS scripts, javascript scripts, these things need to be external, in this way, you can reduce the spider's reading, so that it can quickly locate the site to the point, imagine, if the spider read a lot of JS code, has not entered the site's topic, it will jump straight out, so for you, is not a loss.

4, pictures, Flash is the enemy of spiders

Pictures, Flash is the enemy of spiders, why say so? They can not only slow down the loading speed of the site, but also, the search engine can not read Flash code, so, the page as little as possible or without flash and pictures, if it is possible to appear pictures, but also may be the picture plus the corresponding information.

5, set 404 error page

This is the user friendliness of the consideration, the site error is normal, this error page we can think is a default page, so that he becomes an information page, rather than sorry without this page, the increase in user friendliness, for us, is also very important.

So much to say, these are all relatively basic elements, we often encounter and do not pay attention to the problem, do not look at these content is relatively small, but for SEO optimization, these are the accumulation of dribs and drabs experience, the need for webmaster attention, attention to the details of the problem, I believe that after the completion of your website, will achieve good results.
