- The .htaccess file is a configuration file for your web server. In the context of SEO, it is used to help your web server determine how to route HTTP traffic. In the world of SEO, the .htaccess file is most commonly discussed in the context of URL aliases,which are often used to create search engine friendly URLs.
- A 301 redirect is an instruction given to the web server, informing it that a page that was previously located at one URL has been moved permanently to a new URL. The 301 redirect is most commonly used in situations where a site has been rebuilt and the URLs have changed. By adding 301 redirects to the site, you are able to avoid missed connections caused by traffic going to the old URL. When a 301 redirect is used, the search engines will also update their indexes to remove the old URL for the page and substitute the new one, thereby preserving the page's indexing
- A 302 redirect, like a 301 redirect, informs the web server that a page has moved.Unlike a 301 redirect, a 302 redirect indicates that the move is temporary. This option is a disfavored option as some search engines will penalize for the use of this sort of redirect.
- When a person visits a URL to a page that no longer exists (or has been moved), or types in an incorrect URL, the visitor will automatically be shown a 404 error message. The default message informs the visitor that the page cannot be found. Many sites build custom pages specifically designed to be displayed when a 404 error occurs.
- AdSense is a Google advertising program aimed at website owners. Site owners can sign up for the AdSense program and then display it on their site. (The ad inventory is provided by Google, often from the AdWords program, discussed next). The website owner will be paid a percentage of the revenues generated when someone clicks on one of the ads displayed on his or her site.
- AdWords is a Google commercial advertising program aimed at advertisers. If you want to advertise on the Google network, you can sign up for the AdWords program, build an ad and set a daily budget for the display of that ad. The ad will then appear in the Google network and you will be charged when someone clicks on one of the ads (or, alternatively, you can elect to be charged according to the number of views of the ad).
Alexa Rank
- Alexa.comprovides a website ranking service that attempts to rate all the sites on the Web in order of their popularity. Like a golf score, the lower the score, the better. The most popular site on the Web (typically Google.com) has an Alexa Rank of 1. The service, though not 100 percent accurate and the subject of some criticism, is yet another way of tracking the success of your efforts to raise your site's profile.

- The HTML image tag (img) is used to place images on the page. The tag includes an option to specify a value for the attribute alt. This attribute is intended to allow webmasters to specify an alternative description for the image, typically for the benefit of users who are using screen readers or browsers with the image display disabled.

- Crawl depth is a measure of how deeply the search engine spider has indexed a website. This is typically an issue relevant for sites with a complex hierarchy of pages. The deeper the spider indexes the site, the better.
- Deep link is a hyperlink that points to something other than the front page of a website
- Doorway pageis a page built specifically to point users to another page. This technique is used legitimately when a site owner holds multiple domain names and wishes to channel all the traffic into a primary domain. The technique is often used inappropriately by some black hat SEO practitioners as a way to create highly optimized pages targeting a specific term or terms, then push the users to another site—an online variation of the old bait and switch routine.
- Duplicate content penalty is a theory that the search engines penalize sites that repeat content, or use content that is duplicated from another source. The theory is controversial, with many believing that the penalty may not exist, or may only be enforced in situations where there are other factors that indicate bad intent.
- The Google Webmaster service is provided by Google to enable site owners to gain access to some basic tools that help you diagnose and track your site. Registration is free of charge.
- Internal link density is the number of self-referential links on a site; that is, the number of links on a site pointing to other pages on the same site.
- KEI is an acronym standing for Keyphrase Effectiveness Index. KEI is normally used during keyphrase research in an attempt to find the optimal keyphrases for a site. It is a simple ratio, most often defined as, "Frequency of search engine queries for the term/number of pages competing for the term".More the number of searches, more the potential traffic. The lower the competition, the easier it is to rank highly in the SERP. The most ideal term will have low competition and a high number of searches.
- Keyphrase density is a calculation done by looking at all the text on a page, then calculating a ratio that represents the total number of words to the number of times a particular keyphrase or keyword appears on that page.
- A keyword is a word being targeted for site's SEO efforts. A keyphrase is simply the targeting of a phrase instead of a single word.

- A landing page is a web page that has been optimized to capture a customer, and is typically used as the target for an ad or other promotional campaign, or simply for capturing leads.
- Link building is the process of seeking out or creating links to a site for the purpose of increasing the site's search engine relevance or inbound traffic.
- Link farm is a site that includes an excessive number of links. These sites are typically built purely to generate links for SEO purposes. Sites of this nature are disfavored by the search engines, which view them as inappropriate attempts to exert influence over rankings
Link text (also known as "anchor text")
- When you create a hyperlink on a page by wrapping a text string with an <a>tag, the text wrapped by the tag is referred to as the link or anchor text. There is a search engine optimization benefit to using text for hyperlinks, as the text can then be indexed in conjunction with the hyperlink.
- In general terms, the long tail of a distribution is the trailing end of the distribution. In the context of SEO, the term is used to refer to targeting longer and more specific search queries, where there is usually less competition.
- Metadata is, quite literally, data about data. On the Web, meta tags are the most common implementation of metadata and in the past were a key part of search engine indexing. Today, meta tags are still in use on the Web and can be found in the head section of web pages.
- MozRank is a site ranking algorithm formulated by SeoMoz. Often used in SEO circles as an alternative to Google's PageRank.
- nofollowis a possible value for the relattribute inside the <a>tag. If the value of the relattribute for a link is set to nofollow, the search engines' spiders will not follow or index the link.
- Organic rank refers to natural search engine ranking, as opposed to paid ranking.
- Outbound link is a hyperlink on one site pointing to an external site
- PageRank is a ranking algorithm created by and named for Larry Page at Google. The ranking criteria is unknown, but the scale ranges from zero at the low end to ten at the high end. The higher the score the more persuasive a website is deemed to be. There is argument, however, that the rank is no longer in use at Google and may not continue to evolve.

- The titleattribute is available on a number of HTML elements. It is used to provide a description for a link, a table, a frame, an image, or other elements. Some search engines index the titleattribute and it therefore provides another option for on page optimization. Some browsers will also display the content of the titleattribute as a tool tip when you move your mouse over the object.
- White hat is a label used to describe the use of SEO techniques that are legal, ethical, or exhibit best practices.
- XML sitemaps lists the pages on a website in a format that is easily digestible by search engine agents. The sitemaps follow a standard convention agreed upon by all the major search engines.
