　　1. Search engine Marketing (SEM)

Search engine Marketing (SEM) English is all called search Engine Marketing, meaning the marketing of services and products through search engines. Search engine marketing is mainly divided into two kinds: Search engine optimization (SEO) and pay-click (Ppc,pay-per-click). Search engine Optimization (SEO) means to optimize the site and page and let them display in the search results page, and pay-click (PPC) refers to the purchase of the search engine's click to bring users to their own site. These clicks are "sponsored links" from the search results page, which is clearly not applicable to Baidu.

　　2. Reverse link (backlink)

The reverse link (backlink) is also known as the "Back-link" "In-Link" and "Simple Link", which refers to a hyperlink from another site to your site. Backlinks are important for SEO because they directly affect the page level of a page (PageRank) and the page's ranking in search results.

　　3. Page level (PageRank)

Page Rank (PageRank) is an algorithm rule used by Goolgle to evaluate the importance of a page relative to other pages. The basic meaning of this algorithm rule is that if a page has a link to the B page, it can be viewed as a kind of trust or recommendation for page A on page b. So, if the more backlinks of a page, and the higher the value weighted according to these links, the search engine will judge such pages more important, the page level (PageRank) is higher.

　　4. Link bait (bait chain) (linkbait)

Link Bait (linkbait), as its name suggests, is a piece of content that is present on a website or on a blog in order to attract as many backlinks as possible (the goal is to improve the PR value of the site). Typically, the bait is text content, but it can also be a video, a picture, a quiz, or other popular content. The most classic example of bait content is "ten (Top 10)" because it is a popular topic in some social networking sites (the topic seems to be on the street).

　　5. Mutual chain workshop or mutual chain workshops (link farm)

A chain factory or chain workshop (link farm) is the means by which many Web sites (usually large in number) improve the page rating of each of the groups by linking each other in order to improve the composition of a similar workshop or workshop-style group. Early on, this method was useful, but it has now become a shameful means of cheating (and may receive punishment).

　　6. Anchor text

Anchor text is a clickable text in a page in the reverse link, and the keyword is helpful to search engine optimization (SEO) Because Google Associates these keywords with your content.

　　7. Link attribute-nofollow

Nofollow is a link attribute used by webmasters to tell search engines that they are not voting for a site that the link points to. The link may also be a site user's own creation (such as a link in a blog comment), or a link to a paid transaction (such as a link to an ad or sponsor). When Google recognizes the nofollow properties of these backlinks, it basically does not count the contribution of these links in the algorithm for page ratings and search results rankings.

　　8. Link decoration (links sculpting)

Link sculpting refers to the property settings of the site administrator for the reverse link of other sites on the site. For example, an administrator adds a nofollow attribute to a link, which allows an administrator to decide to use his or her own site to improve the page rating for a particular site or not to help a particular site improve its rating. Now, however, this practice has been minimal because Google has decided to use its own algorithm to determine how to handle the nofollow attribute of the link.

　　9. Page title (title Tag)

Page title (title Tag), as the name implies refers to the title of a page, which is Google search algorithm, the most important reference. In theory, your page title should be unique and include as many keywords as possible in the page's content. You can see the title of a page from the top of the browser when browsing the web.

　　10. Meta tags (meta tags)

META tags (meta tags) and page titles are generally used to provide search engines with more information about the content of your page. The META tag is located in the head of the HTML code and is not visible to visitors with long eyes.

　　11. Searching algorithm (search algorithm)

Google's search algorithm is designed to find the most relevant sites and pages for each search request. This algorithm considers more than 200 kinds of factors (Google claims), including page rank, title, meta tags, site content, and the age of domain names.

　　12. Search results page (SERP)

Search results page (SERP) in English is all called Search Engine Results page. Basically, this is the page you normally enter after entering the keyword in google. The amount of traffic your site gets from this page depends on the ranking of your site in search results.

　　13. Sand Box (Sandbox)

In addition to the index of all the sites, Google also has a separate index sandbox, which is a newly discovered and included Web site. When your site is in the sandbox, it will not appear in general search results, and only if Google confirms that your site is legitimate, it will move it from the sandbox to the index of all the sites.

　　14. Keyword density (Keyword density)

How do you judge the keyword density of a particular page? All you have to do is divide the number of words you use into a single keyword by dividing the total word count on the page. Keyword density used to be a very important factor in search engine optimization, because early search algorithms were highly valued, but now things have changed.

　　15. Keyword accumulation (Keyword stuffing)
