网站优化中的内部链接和外部链接?

一、内部链接

指通过用户点击此超链接,将用户从一个域名的页面引导到同域名下另外一个页面。


我们可以打一个比方,如果说你的网站是一张零散蜘蛛网的话,那么内部链接就是这张网上的一条条相互连接的线,它将这个零散的网变成一个有机的整体。


内部链接可以降网站的内容相互串联形成整体!


内链还方便用户在你的网站中浏览以外,它在网站SEO也有着不小的作用:


1、提高网站内容的关联性,帮助链接的价值在整个网站上流动,从而使链接的价值不只停留在一个页面上而是整个网站中;


2、帮助搜索引擎蜘蛛找到并抓取你网站的所有页面,从而避免孤岛页面的出现;


3、页面关联性提高,页面价值增大,从而提高网站的自然排名.


问:既然内部链接的价值这么大,我们是否可以在自己的页面里建立成百上千个内部链接从而达到提升网站排名的效果呢?


答:当然不行的哦。


搜索引擎从根本上杜绝了这种情况的发生,搜索引擎认为外部链接在网站排名时具有更大的价值,因此如果页面大量的充斥内部链接,对于网站的排名不仅没有提升,反而会让搜索引擎认为你的网页有着过度优化的嫌疑从而让你的页面权重变低,因而导致你的页面排名下降。

二、外部链接

指通过用户点击此超链接,将用户从一个域名下的页面引导到另一个域名下的页面。


那么此处我们也可以做一个比方,如果说内部链接是链接构筑网内部的线条的话,那么外部链接就是将一张网同另一张网连接起来的树枝或者丝线。


同样的,外部链接也有着不容小觑的网站优化功能:


1、高质量,高权威的外部链接将对你的网站排名有着极佳的促进作用,反之,则会对你的网站造成巨大的损害;


2、关联到与网站内容极相关的其他网站,可以提高你网站内容的可信度,从而提高网站的价值;


3、可以与其他的网站建立友好联系,在一定程度上还能促使网站双方的所属公司建立有的合作关系,为日后的发展奠定基础。


问:既然外部链接比内部链接重要,我们是否可以大量去申请或者购买外部链接来提升我们的网站排名呢?


答:当然不行。在你去申请或者购买外部链接时,你还需要考虑以下的信息:


1、网站内容相关度


如果你的网站是以建材为主题的,那么你的外部链接肯定不能是农业网站,因为这两者基本没有什么相关性。


2、外部链接页面的权威性


外部链接在搜索引擎看来就犹如一个网站对于另一个网站的“投票”,自然而然,网站权威越高,那么它的外部链接的价值也就越大。


3、有害链接


对于网站内部存在有害链接的网站会有一定的处罚措施,因此,当你在申请外部链接时,你需要检查这个外部链接的网站是否是有害网站或者无效网站。


4、根域名的数量


链接的相关性、权威性和质量是外部链接的最重要指标,但数量也很重要。如果你有两个网站都有相关的高质量链接,那么拥有较高数量的网站更有可能获得高排名。


5、锚文本


外部链接的锚文本应该是一系列自然的关键词变化和自然语言,指向你的目标页面。也就是说,如果你的网站页面的关键词是“不锈钢铁柜”,那么外链给到的超链接文本也最好是“不锈钢铁柜”。


6、nofollow和dofollow


nofollow标签是向搜索引擎爬虫表明,所链接的网页不应该与你的网页相关联,也即对网站的排名没有任何作用,而dofollow则告诉搜索引擎关注该链接和相关网站。现在搜索引擎更新了nofollow的标准,让nofollow的链接也会对网站的排名起到一定的优化作用,但当你在申请外部链接的时候还是更应该考虑链接的标签是否为dofollow而不是nofollow



英文翻译对照:


Internal and external links in website optimization?

1、 Internal links

It refers to guiding users from the page of one domain name to another page under the same domain name by clicking this hyperlink.

We can make an example. If your website is a scattered spider web, the internal link is the interconnected lines of the web, which turns the scattered web into an organic whole.

Internal links can reduce the content of the website and connect with each other to form a whole!

The internal chain also facilitates users to browse in your website. In addition, it also plays a great role in website SEO:

1. Improve the relevance of website content and help the value of links flow on the whole website, so that the value of links does not stay on one page, but in the whole website;

2. Help search engine spiders find and grab all the pages of your website, so as to avoid the emergence of island pages;

3. The page relevance is improved and the page value is increased, so as to improve the natural ranking of the website

Q: since the value of internal links is so great, can we establish hundreds of internal links in our own pages to improve the website ranking?

A: of course not.

Search engines fundamentally put an end to this situation. Search engines believe that external links have greater value in website ranking. Therefore, if a large number of pages are filled with internal links, the ranking of the website will not be improved. On the contrary, search engines will think that your website is suspected of over optimization, so as to reduce the weight of your page, resulting in the decline of your page ranking.

2、 External links

It refers to guiding users from the page under one domain name to the page under another domain name by clicking this hyperlink.

So here we can also make an example. If the internal link is the line connecting the internal structure of the network, the external link is the branch or silk thread connecting one network with another.

Similarly, external links also have website optimization functions that can not be underestimated:

1. High quality and authoritative external links will play an excellent role in promoting your website ranking. On the contrary, it will cause great damage to your website;

2. Linking to other websites that are highly related to the website content can improve the credibility of your website content and improve the value of your website;

3. It can establish friendly contacts with other websites and, to a certain extent, promote the affiliated companies of both websites to establish some cooperative relations, so as to lay a foundation for future development.

Q: since external links are more important than internal links, can we apply for or buy a large number of external links to improve our website ranking?

A: of course not. When you apply for or buy external links, you also need to consider the following information:

1. Website content relevance

If your website is themed with building materials, then your external links must not be agricultural websites, because the two are basically irrelevant.

2. Authority of external link pages

External links in search engines look like a website's "vote" for another website. Naturally, the higher the authority of the website, the greater the value of its external links.

3. Harmful link

There will be certain penalties for websites with harmful links inside the website. Therefore, when you apply for external links, you need to check whether the website with external links is harmful or invalid.

4. Number of root domain names

The relevance, authority and quality of links are the most important indicators of external links, but the quantity is also very important. If you have two websites with relevant high-quality links, websites with a higher number are more likely to get high ranking.

5. Anchor text

The anchor text of external links should be a series of natural keyword changes and natural language, pointing to your target page. In other words, if the keyword of your website page is "stainless steel cabinet", the hyperlink text given by the external chain should also be "stainless steel cabinet".

6. Nofollow and dofollow

Nofollow tag indicates to search engine crawlers that the linked page should not be associated with your page, that is, it has no effect on the ranking of the website, while dofollow tells search engines to pay attention to the link and related websites. Now the search engine has updated the nofollow standard, so that the nofollow link will also play a certain role in optimizing the ranking of the website. However, when you apply for external links, you should consider whether the label of the link is dofollow rather than nofollow
