Search engine optimization, referred to as SEO, is to improve your ranking in various search engines, get a good ranking is the effect of SEO.

SEO is a complex thing, including many, first of all, you have to determine a website keyword, the so-called keyword is what your site to do, the core product is what, that is, customers and target customers in search engines to find the input of the Web site words.

The choice strategy of keyword

First of all to determine the core keywords, and then around the core keywords to arrange the combination of keyword group or phrase (long tail keyword), for businesses and businesses, the core keywords is their business scope, such as products/services, industry positioning, as well as business name and brand name. Tips for selecting keywords: from the point of view of the user, expand the keywords into a series of phrases and sentences; Do multiple permutations and combinations; do not use keywords that are too generic, use your own brand keywords, review keywords used by competitors, and don't use keywords that are not related to your site.

Be sure to control the number of keywords, a page of more than 3 keywords, all content to be around these key words to expand to ensure that the keyword density is reasonable. Search engines also think the theme of the page is clear. If you determine a large number of keyword rendering, you can write to spread to other pages and targeted optimization, so that these pages also have a "door page" effect. This is also the home page and the keywords often have to distinguish between the reasons.

When choosing the keyword, if it is a new station, we should choose the words which are not strong in competition. If you must do a strong competitive word, it is recommended to do long tail words, with long tail keyword driven by the main keyword ranking, that is, the so-called long tail effect, meaning that the long tail keyword ranking up, the main keyword ranking will follow up.

1, keyword density

After you have identified your keywords, you need to appear in the appropriate place on the page. Keywords appear in the page frequency is called keyword density (keywords densicy), is a page, accounting for all of the page in the proportion of the total text, the index on search engine optimization plays an important role, the keyword density is generally in 3%-15% timely. (But as long as the natural appearance, 20% does not matter, I have seen)

2, the distribution of key words

(A) title and meta tags in the Web page code (source file options in view)

Title. Try to contain your site's content and core keywords, take your site's name, the number of words in the control within 30,

Keywords, is the key word, just listed here you think the appropriate, can highlight the content of the keyword on the site can be, not too much, 10 or 8 can be, much useless, search engines will only browse the front of a few, the rest are waste. But there is a point to understand that the mainstream search engines are no longer rely on the keyword, so this part of the content we are only "routine", the individual feel little significance, but better than No. (Relevant keywords can give you a URL reference https://adwords.google.com/select/KeywordToolExternal?defaultView=2)

Description, is the description, should be in almost descriptive language to write a paragraph about your site, in which you should be appropriate to the characteristics of your site to repeat to highlight the content.

(b) Text of the Web page

The content of the Web page should be appropriate to the occurrence of keywords, and have a "focus, the intention to follow the user's habit of reading the priority position." From top to bottom, from left to right, to become the key point distribution location, including the top of the page, the left, the title, the top 200 words within the text, in these places the keyword is very helpful in ranking.

(c) Hyperlinks

Consciously use keywords in navigation, sitemap, anchor text

D Header Label

Body Label

Between the text. Search engines pay more attention to the text in the title. Bold text is often the place where keywords appear. Not too many times.

E Picture alt Attribute

Search engines can not crawl pictures, so when the page is produced in the image alt attribute keyword is a good way to search engine friendly, it will try the picture and keyword content consistent, strong and ranked.

Two pairs of search engine friendly web page structure

1 directory Structure and URL

A URL is a Uniform resource location, which is the URL and path of each Web page. The directory structure of the website file directly embodies the URL, the clear short directory structure and the naming of the specification, not only beneficial to the user's experience and website dissemination, but also the search engine friendly experience.

A) directory hierarchy

For small sites, subdirectories have only one layer, such as http://www.beijingdasong.com/dirl1/page.html, www. Beijingdasong.com is the domain name, Dirl is a directory name, page is the file name, for search engines, this simple directory structure is the most ideal, that is, flat structure (flat)

For large-scale web sites, often need two to three levels of subdirectories, such as: http://www. Beijingdasong.com/dirl1/dirl2/dirl3/page.html, search engines will still crawl to level two three subdirectory. As few directory names as possible are easier to crawl.

b Directory and file naming

According to the principle of ubiquitous keyword, you can use keywords in the directory and file name, if the keyword group, to use the connector separate "-"

c) the shorter the URL the better

2) Navigation structure

Site navigation is to guide users to visit the site's columns, menus, online help, layout structure, such as the formation of the generic, its main function is to guide users to access the content of the Web site, is to evaluate the professional degree of Web pages, availability of important indicators. At the same time to the search engine can produce a lot of prompt effect.

A The main navigation clear and eye-catching

Main navigation is generally reflected as a level of directory, through their users and spider programs can be in-depth look at layers

The main content of the website. Therefore, the main section of the site is necessary in the first screen eye-catching position embodiment, and it is best to use text links instead of picture links.

B "breadcrumbs" path

The so-called bread crumbs is the metaphor of the user through the main navigation to reach the target page in the process of access prompts, so that users understand the site location of users, not "lost", and easy to return to the superior page and starting point. Each column in the path is best to add a link. There is no detailed path source, at least in each of the child pages also have the hint back to the homepage of the link. Include the logo link for the page.

c) Home Highlights important content

In addition to the home directory, you should also place important content in the secondary directory in the form of links, multiple times on the home page and other pages to highlight the focus. This is a great help to the Web level (PR).

D use Sitemap (Google sitemap)

Site Map is a tool to assist navigation, for the site map design, layout must be concise, all the links are standard HTML text, easy to be crushed by spiders, it is easy to find important pages (important pages include: Home page, main category page, help page, contact information page, etc.), The most important thing is that each page should be wind-induced site map links.

3 Frame Structure

Frame structure is the frame structure of a Web page is fixed, the other part of the information can be moved up and down through the scroll bar display, such as the left menu fixed, the body information can be moved, or the top navigation and logo parts fixed, the other part of the information moved up and down.

The superiority of the frame-type website is embodied in the overall consistency of the website and the convenience of updating. The frame structure can make the maintenance of the website easier. Using the frame structure, you must optimize using the "nofames" tag in your code, think of the Nofames label as the home page of an ordinary text content, include a link to the frame in the zone and a descriptive text with a keyword, and a keyword text in an area outside of the frame, This allows search engines to correctly index information within the framework.

Another method is to use the IFRAME, the internal chain framework technology to avoid the inconvenience caused by frame. An IFRAME is equivalent to a child window embedded in the main browsing window and the content is automatically opened. An IFRAME can be embedded in any part of a Web page, or it can be defined at any time, and its code is:

It is recommended that this mode be used sparingly, but to improve PR, we should use it flexibly.

The PR is GG to the website rank of a factor, GG to the site's ranking a large part depends on the PR quality of GG. But now the PR weight is reduced.

4 Image optimization

The core of image optimization is to increase the visible text description of search engines, and to compress image size as much as possible while guaranteeing the image quality.

Each image has an alt attribute, with a text representation and a keyword on the page in each attribute.

SEO suggested that the site head appears less pictures, suggest using title to do the description, large image slice processing, and the site title relative to, alt writing can not be repeated

5 The use of the table

The table is the most important layout of the page, if a page with a large length of text, you can divide it into several pages, you can insert a table

6 Page Weight Loss

Reduce the size of the page file, you can speed up the loading of the page, under normal circumstances a page size can be around 15k, preferably not more than 50k

7 website Layout

Recommended site layout mode with Div, a large number of optimized code, increase the speed of the site to open, SEO optimization is also helpful.

4 Specific Optimizations

Dynamic page optimization

is the dynamic page to do static processing, made pseudo static, or some background can be directly generated, search engine for static page crawl easier.

Three-link strategy

Five other aspects of optimization

Content

1 original content of the best, should not be repeatedly reproduced content

2 content independence, at least 30% different from other pages

3 1000-2000 words, reasonable segmentation

4 regular updates, preferably every day

5 content around the page keyword expansion, and the whole station related to the theme

6 comment function, keyword in comment

Outside chain

I. Soft text promotion. (Best effect)

In a technical form to discuss the sharing of their own experience, but need to pay attention to, plug the link not too much, and the article directly transformed into advertising. The chances of this being widely reproduced are greatly reduced, to summarize their experience, there is the form of technology sharing and discussion. Because the soft text can be promoted in most of the time will not be judged as pure advertising and was edited, the administrator deleted. Believe that if you can get knowledge content, valuable articles. Admin is not deleted.

Two. Free resource form (fastest spread)

By tidying up some books of their own study, or good software. Provided with the download address. A skilled friend can develop a good announcement, provide online challenge assistance, or a good free resource. This method can be spread quickly in a short time, not only for the site can get links, And your website may attract him to continue to come to your site.

Three. Network links

This may not be suitable for novice webmaster, through a period of accumulation can be.

Know webmaster friends A lot of ways, more on some with SEO-related forums, QQ group, in others have difficulties, there are problems, if they have the ability to help, help one. Do not dive, you can participate in a discussion when you meet a topic of interest.

Four. Article Competition activity

If there is a certain size of the site, you can hold a series of games. For example: SEO a keyword game and so on.

The weight is refers to the search engine to your website attention degree, the general time is longer, the renewal frequent website weight is relatively high.

Search engine is how to judge the importance of a page, or the search engine rankings how the principle of work, we can simulate ourselves is a search engine, if you are going to do search engines how do you judge the weight of the rankings? Nothing but the following levels

1. Domain Name

2. Catalogue

3. Single page

These three-level plex relationships are domain name > directory > Single page

First from the search engine Spiders crawl The page of the process to see, spiders must first know is your domain name, then certain domain names contain keywords or keyword Pinyin is the most important, spiders crawl your domain name, he will certainly analyze your domain name under the number of directories, spiders will first crawl back to the directory, Then crawl down one level below the directory. Obviously, it is important to remove keywords in the catalogue, of course, sometimes your domain name root directory is not necessarily the only directory, there will be some single pages, such as: www.beijingdasong.com/aboutus.html Such a single page in the search engine weight must be higher than the single page in the directory. When the spider crawled out of the directory will start to crawl the specific page, then the page's keyword weight and density settings, as well as the page contains the keyword link density is a search engine reference an important factor. All of these factors are the first things you should consider when setting up a website these factors are related to the structure of the site design, and often for a site's overall keyword optimization is not limited to a single keyword, but to optimize the keyword group you are reasonably distributed to your site, and the structure of your site to match. You can divide the keywords into three levels, if we take "QQ" this keyword as an example, "QQ" is the core keyword we want to do, of course, "QQ" The word also has a lot of related extension keywords, such as: QQ space, QQ space Code, QQ personality signature, and so many two-level expansion of keywords, Then we in the design of the site structure, we need to "QQ" as the core keywords, this word must appear in the domain name, and those two-level extension keyword can be our sub column in the directory name, to the third level of the page is our specific to optimize the level three keywords, such as our "QQ space" This sub column contains "QQ space message code" such a single page. In other words, the site page structure contains the key to the importance of the keyword and you want to optimize the keyword is to match the importance of the key words to put in an important position. That's three.

1 Domain name is best to include your core keywords, if the domain name does not contain keywords, then your site name must contain the core keywords

2 from the core keywords in the expansion of the two-level keywords as your column name, this can be counted as a keyword two classification

3 from the two-level keyword expansion of the three-level keyword as you want to add a single page of the main keywords, that is, the specific content page keywords

The weight of the keyword will also have passed, if according to the above three to design the distribution of keywords, then we can see that the core keywords will appear in three levels of the page, two-level keywords will appear in two levels of the page, and the most peripheral keywords that we often say long tail keyword is distributed on the specific page. This type of keyword layout design will be a pyramid. In this way we will not be able to optimize the keyword optimization. Many times we choose the keyword is very difficult, this keyword also want, that keyword also want, what keyword want. But the main key to each page can only be set one. So many webmasters have encountered confusion, there is no choice, but if you grade the keyword, and then according to what I said this pyramid-shaped keyword layout, you will not be confused.

Of course, the layout of the key words is only a site ranking internal cause, this is a site to get a good ranking of the basis, and external factors or depending on your outside links, many friends do external links have a misunderstanding, that is, only for the core of the key words of the external connection, this is because you do not know what is a friendship link, What is an external link, links need to use your core keywords to do the link, because this link is a direct link to your domain name, and for your two-level keywords you need some external links (sometimes two-level keywords external links can use the site's internal columns to complement each other), The same reason your two-level keyword links to link to other people's Level two page, do the link to do the same keyword layout design, each level of keywords external links should be different, not a key word to conquer. Different levels of the page, links also need to be different.

Summary, do SEO In fact, you insist on, as long as you adhere to update every day, more to do some original content, multiple links, and other sites to do more good relations, this is the real seoer.
