my experience is that a large number of related articles+reasonable links in the site+stable update frequency.

How to do a good job in seo optimization strategy can refer to the following methods:

In search engine optimization, SEO strategy affects the final optimization effect. SEO strategy is important for both small and medium-sized websites and large websites, and it is particularly important for large websites to formulate a good SEO strategy.

Part I: Keyword analysis

Keyword analysis is a course that all SEO must master. Although large websites have a huge amount of data, every page needs keyword analysis. Besides SEO, planning and editing also need to have certain keyword analysis ability.

Basic principles of keyword analysis:

1. Investigate users' search habits: This is an important aspect. Only by understanding users' search habits can we know our users' search needs and what users like to search for. What search engine is used? And so on

2. keywords should not be too broad: too broad keywords will lead to fierce competition, spend a lot of time but may not get the desired effect, and may reduce the relevance of keywords.

3. keywords should not be too cold: think about it, is it worth optimizing without keywords searched by users?

4. keywords should be highly correlated with the content of the page: this is beneficial to both optimization and users.

Steps of keyword selection:

1. Determine the core keywords: Which word or two words should we consider to describe the content of the webpage most accurately? Which word is searched by users the most?

2. Expansion of the definition of core keywords: for example, the alias of core keywords, the combination next to core keywords, and the assistance of core keywords.

3. Design keywords by simulating users' thinking: Imagine myself as a user, so what keywords will I search for?

4. Research the keywords of competitors: Analyze the websites of competitors with dominant rankings. What keywords do they use?

part ii: page reverse optimization

why do you want to do reverse optimization? Because in large websites, the optimization value of pages is generally different from that of small and medium-sized websites. Considering various comprehensive factors (such as brand, page content, user experience, etc.), the page optimization value of large-scale websites mostly presents reverse order, namely: final page >; Thematic page > Columns page > Channel page > Home page.

how to assign keywords to each page? Usually the situation is like this:

1. Final page: for long-tail keywords;

2. Thematic pages: for popular keywords, such as "Jay Chou";

3. columns page: For fixed keywords, such as "music audition";

4. Channel page: for core keywords, such as "music";

5. Home page: Do not assign keywords, but focus on brands.

after keyword assignment, we can add matching internal links to the final page as an aid, which is the advantage of internal links in large websites.

Part III: Front-end search engine friendliness, including search friendliness of UI design and search friendliness of front-end code.

1. First, let's look at search engine friendliness of UI design: navigation is clear, and flash and pictures are used. Generally speaking, navigation and parts with keywords are not suitable for using flash and pictures, because most search engines can't capture the characters in flash and pictures.

2. Search engine friendliness of front-end code:

A. Simplicity of code: Search engines like concise html code, which is more conducive to analysis.

B. Important information comes first: refers to the information with keywords and frequently updated, which should appear in the front position of html as far as possible.

c, filtering interference information: the pages of large websites are generally complicated, and there are many advertisements, cooperation, exchange content and other irrelevant information. We should choose to use codes that search engines such as js and iframe can't recognize to filter out this part of information.

D. Basic SEO of code: This is the basic SEO work to avoid html errors and semantic tags.

part iv: internal link strategy

why should we emphasize internal link strategy? Because internal links have the following advantages:

1. The massive data of large websites make the advantages of internal links far greater than those of external links. The number of external links may be tens of thousands or hundreds of thousands, but large websites have millions or even hundreds of millions of pages. If these massive pages are used to build internal links, the advantages are obvious.

2. It is easy to export links between pages in a website.

3. Improving the crawling index efficiency of search engines to websites and enhancing the collection are also beneficial to the delivery of PR.

4. Focus on the topic, so that the keywords of this topic have a ranking advantage in search engines.

In the construction of internal links, the following principles should be followed: 1. Control the number of internal links in articles: the number of links inserted in articles can be controlled at around 3-8 according to the content. 2. The relevance of linked objects should be high. 3. Pay more attention to important web pages: make important web pages with more keyword value get better rankings. 4. Use an absolute path.

Part V: External Link Strategy

While emphasizing the internal chain construction of large-scale websites, we should not neglect the external chain construction too much. Although the construction of external links is not as important as small and medium-sized websites, it also has high value. Usually, the external chain can be built by link exchange, making link bait, and putting in soft articles with links.

1. Let's see what principles link exchange should follow:

A. Link words contain keywords; B, try to link exchange with sites and channels with high correlation; C, the number of links exported from the other website should not be too much, which is of little value; D, avoid link exchange with websites that are not included and punished by search engines

2, make link bait: making link bait is a labor-saving work, which makes the other website actively add links for us. There are many techniques to make link bait, but they can be summarized in two words: creativity.

3. Put in soft articles with links. Refers to the delivery of soft articles with links in business promotion or for the purpose of obtaining external links.

Part VI: Website Map Strategy

There are many large websites that don't pay attention to the construction of website maps, and many large websites' website maps are just perfunctory and just a decoration. In fact, websites are very important for large websites. The massive data of large websites, complicated website navigation structure and extremely fast update frequency make search engines unable to completely capture all the web pages. This is an important reason why some large websites have millions or even hundreds of millions of data, but only half, one third or even less of the data of the websites are included by search engines. Even if you can't guarantee the inclusion, how can you rank?

Html map:

1. Establish a good navigation structure for search engines.

2. Html maps can be divided into horizontal navigation and vertical navigation. Horizontal navigation mainly refers to links such as channels, columns and special topics, while vertical navigation mainly focuses on keywords.

3. Every page has a link to the website map.

Xml website map: mainly aimed at search engines such as Google, yahoo and live. Because the data volume of large websites is too large, a single sitemap will lead to a too large sitemap.xml file, which exceeds the tolerance of search engines. Therefore, we need to split the sitemap.xml into several pieces, and each split sitemap.xml remains within the range suggested by the search engine.

Part VII: Search engine friendly writing strategy

Search engine friendly writing is a key part of creating massive data to obtain a good search engine ranking. It is impossible for SEO personnel to put forward SEO suggestions or schemes for every web page, so the training of writers is particularly important. If all writers write according to the principle of search engine friendliness, the effect will be terrible.

1. Repeated training should be given to writers: writers are not SEO and have no experience, so it is impossible to understand SEO writing skills at once. Therefore, it is necessary to train the writers repeatedly to achieve the effect.

2. When creating content, first think about what users will search for, and write according to users' search needs.

3. Pay attention to title and Meta-writing: For example, although the weight of meta in search engines is already very low, bad meta-writing, such as piling up keywords and keywords irrelevant to the content, will have negative effects. The Title has a high weight, so try to incorporate keywords into the Title.

4. Integration of content and keywords: keywords should be properly integrated into the content, so that the keywords appear in the appropriate position and maintain an appropriate keyword density.

5. It is very important to add links for keywords: adding links for related keywords, or adding links for keywords of other pages that appear on this page, can make good use of the advantages of internal links.

6. Use semantic tags for keywords:

Part VIII: Log analysis and data mining

Log analysis and data mining are often ignored by us. In fact, whether it is a large website or a small or medium-sized website, it is a very meaningful work. It's just that the log analysis and data mining of large websites are more difficult, because the amount of data is too large, so we should have enough patience to do this work and be targeted.

1. Website log analysis: There are many types of website log analysis, such as access source, browser, client screen size, portal, bounce rate, PV, etc. There are three main types that are most related to SEO work: a, search engine traffic import; B, keyword analysis of search engine; C. statistical analysis of users' search behavior

2. hot data mining: we can mine hot data through our own website log analysis, some external tools and SEO's own ability to grasp hot spots. Hot data mining mainly has the following means: a, grasping industry hot spots, which can be completed by editing and SEO***; B. Predicting potential hot spots requires high sensitivity to information and can predict potential hot information. C. Create hot spots by yourself, such as hype; D, making special topics for hot spots

Part IX: Creating special topics for keywords

In addition to the final page, all kinds of special topics made for hot keywords should be the second largest search engine traffic source of the website. After mining the hot data, we can make special topics for these hot keywords. Where did the content of the special page come from? We generally filter and aggregate the information related to the corresponding keywords through programs, so that the content is highly matched with the keywords, and the required content is provided for users and search engines.

Of course, it is difficult to guarantee the search engine ranking of a topic only by establishing a topic without auxiliary means. We can achieve the effect by obtaining links through internal links of articles, recommendation of channel pages, or special recommendation of final pages.

1. Making special topics for hot keywords

2. Aggregating related information of keywords

3. Introducing links in articles.
