I remember when I first contacted the IFRAME frame, to it is not very understanding, feel the usefulness is not small, however, recently in the site with a micro-blog live control when encountered it, but also have to take the perspective of SEO to consider it, after analysis, I think the ifame framework has some advantages and disadvantages.
first we need to know what is the IFRAME framework?
If we use this tag on a particular page, we'll build a separate frame within that page, for example, in a region within page 1, use Ifram to invoke another page, that is, page 2, which will call the part of the page 2 that is called in Page 1. How to use:
or other pages of this article, and so on to write the tag inside, now let us look at the SEO perspective, the use of the IFRAME in our site the advantages and disadvantages of the framework.
One: Disadvantages
At present, all search engines are unable to identify the page Ifram frame called links, text, pictures and so on content, because it is very simple because the content does not belong to the page, but only when the user visited the temporary call, and in Baidu's search engine optimization can only be seen: "frame/ Frameset/iframe label, will cause Baidu spider crawl difficulty, suggest not to use ". This can clearly see the drawbacks of its existence.
second, the advantages
From the above we can find that the use of the ifame framework of the drawbacks is not to be crawled by search engines crawl. But everything always has two sides. It's also possible that this shortcoming is a bit of his. With this, we can take a look at some of our users on our site, but do not need search engine crawling content with ifame frame to display, so that can let Ifram play a real effect, and the code in our site can also be greatly streamlined, for example, As the author mentioned above to add micro-blog live information, we don't need to provide a search engine for these tweets, and we need to provide an interactive experience with the visitors, as shown in the following illustration, and if we use the Ifame framework to embed the information, we can not only easily add the site's micro-blog live platform, At the same time we see that the code is also very streamlined.
Out of the micro-blogging space above, the most common to the IFRAME frame is in the site copyright information, as shown in the following figure, we can be the site's copyright information and some authentication information as to the IFRAME framework, so that both the site in the visitor seems more authoritative, At the same time also can be very good to prevent the weight of the site unnecessary loss.
We can see that the user of the Ifame framework is still very large, but I do not recommend that the page put too much ifame framework, because if there are too many ifame frame on the page will dilute the keyword density of your page and affect it, the search engine may also think you are using cheating means, I think it should not be used in many degrees.
Although this is only a small detail, but the impact on the site is very large. How to choose to use according to the actual situation of their own site. Article by Taobao http://www.hza.cn/Edit, reprint please keep the source.
