Crawler
Also known as Spider or Robot, a crawler is a search engine program that “crawls” the web, collecting data, following links, making copies of new and updated sites, and storing URLs in the search engine’s Index. This allows search engines to provide faster and more up-to-date listings.
Delisted
Also known as banned or blacklisted, a delisted site is a URL that has been removed from a search engine’s Index, typically for engaging in Black Hat SEO. Delisted sites are ignored by search engines.
Description Tag
Also known as a meta description tag, a description tag is a short HTML paragraph that provides search engines with a description of a page’s content for search engine Index purposes. The description tag is not displayed on the website itself, and may or may not be displayed in the search engine’s listing for that site. Search engines are now giving less importance to description tags in lieu of actual page content.
Directory
A directory is an Index of websites compiled by people rather than a Crawler. Directories can be general or divided into specific categories and subcategories. A directory’s servers provide relevant lists of registered sites in response to user queries. Directory Registration is thus an important method for building inbound links and improving SEO performance. However, the decision to include a site and its directory rank or categorization is determined by directory editors rather than an Algorithm. Some directories accept free submissions while others require payment for listing. The most popular directories include Yahoo!, The Open Directory Project, and LookSmart.
Doorway Page
Also known as a gateway page or jump page, a doorway page is a URL with minimal content designed to rank highly for a specific keyword and redirect visitors to a homepage or designated Landing Page. Some search engines frown on doorway pages as a softer form of Cloaking or Spam. However, doorway pages may be legitimate landing pages designed to measure the success of a promotional campaign, and they are commonly allowed in Paid Listings.

Cost-Per-Acquisition (CPA)
Cost-per-acquisition (CPA) is a return on investment model in which return is measured by dividing total click/marketing costs by the number of Conversions achieved. Total acquisition costs ÷ number of conversions = CPA. CPA is also used as a synonym for Cost-Per-Action.
Cost-Per-Action (CPA)
In a cost-per-action advertising revenue system, advertisers are charged a Conversion-based fee, i.e. each time a user buys a product, opens an account, or requests a free trial. CPA is also known as cost-per-acquisition, though the term cost-per-acquisition can be confusing because it also refers to a return on investment model.
Cost-Per-Click (CPC)
Also known as pay-per-click or pay-for-performance, cost-per-click is an advertising revenue system used by search engines and ad networks in which advertising companies pay an agreed amount for each click of their ads. This Click-Through Rate-based payment structure is considered by some advertisers to be more cost-effective than the Cost-Per-Thousand payment structure, but it can at times lead to Click Fraud.
Cost-Per-Thousand (CPM)
Also known as cost-per-impression or CPM for cost-per-mille (mille is the Latin word for thousand), cost-per-thousand is an advertising revenue system used by search engines and ad networks in which advertising companies pay an agreed amount for every 1,000 users who see their ads, regardless of whether a click-through or conversion is achieved. CPM is typically used for Banner Ad sales, while Cost-Per-Click is typically used for text link advertising.

Click-through rate is the percentage of users who click on an advertising link or search engine site listing out of the total number of people who see it, i.e. four click-throughs out of ten views is a 40% CTR.
Contextual Link Inventory (CLI)Search engines/advertising networks use their contextual link inventory to match keyword-relevant text-link advertising with site content. CLI is generated based on listings of website pages with content that the ad-server deems a relevant keyword match. Ad networks further refine CLI relevancy by monitoring the Click-Through Rate of the displayed ads.
Cloaking
Cloaking is the presentation of alternative pages to a search engine Spider so that it will record different content for a URL than what a human browser would see. Cloaking is typically done to achieve a higher search engine position or to trick users into visiting a site. In such cases cloaking is considered to be Black Hat SEO and the offending URL could be Blacklisted. However, cloaking is sometimes used to deliver personalized content based on a browser’s IP address and/or user-agent HTTP header. Such cloaking should only be practiced with a search engine’s knowledge or it could be construed as black hat cloaking.
Conversion
Conversion is the term used for any significant action a user takes while visiting a site, i.e. making a purchase, requesting information, or registering for an account.
Conversion Analytics
Conversion analytics is a branch of Analytics concerned specifically with conversion-related information from organic and paid search engine traffic, such as the keywords converts used in their queries, the type of conversion that resulted, landing page paths, search engine used, etc.
Conversion Rate
Conversion rate is the next step up from Click-Through Rate. It’s the percentage of all site visitors who “convert” (make a purchase, register, request information, etc.). If three users buy products and one user requests a catalogue out of ten daily visitors, a site’s conversion rate is 40%.

Algorithm
An algorithm is a set of finite, ordered steps for solving a mathematical problem. Each Search Engine uses a proprietary algorithm set to calculate the relevance of its indexed web pages to your particular Query. The result of this process is a list of sites ranked in the order that the search engine deemed most relevant. Search engine algorithms are closely guarded in order to prevent exploitation of algorithmic results. Search algorithms are also changed frequently to incorporate new data and improve relevancy.
Algorithmic Results
Algorithmic results are the ranked listings search engines provide in response to a Query. They are often referred to as Organic Listings in contrast to Paid Listings because their rank is based on relevancy rather than advertising revenue paid to the search engine. However, paid listings do appear alongside algorithmic results in many search engines, provided they are relevant. Improving a website’s unpaid algorithmic results is known as Natural Search Engine Optimization.
Alt Tag/Alt Text
An alt tag is the HTML text that appears while an image is loading or when a cursor is positioned over an image. Alt text is useful in Search Engine Optimization because it can include keywords that a search engine looks for in response to a query.
Analytics
Analytics refers to all the technology, programming, and data used in Search Engine Marketing to analyze a website’s performance or the success of an Internet marketing campaign.
Also known as link text, anchor text is the visible, clickable text between the HTML anchor and tags. Clicking on anchor text activates a Hyperlink to another web site. Anchor text is very important in Search Engine Optimization because search engine algorithms consider the Hyperlink keywords as relevant to the Landing Page.
Backlinks
Also known as back link, backward link, or inbound links, backlinks are all of the links on other websites that direct the users who click on them to your site. Backlinks can significantly improve your site’s search rankings, particularly if they contain Anchor Text keywords relevant to your site and are located on sites with high Page Rank.
Banned
Also known as delisted or blacklisted, a banned site is a URL that has been removed from a search engine’s Index, typically for engaging in Black Hat SEO. Banned sites are ignored by search engines.
Banner Ad
A banner ad is a rectangular graphic advertisement. Banner ads are one of the commonest forms of online advertising. Their sizes vary, but most measure 468 pixels wide by 60 pixels high. Clicking on a banner ad will direct you to the advertiser’s website or a designated Landing Page.
Black Hat SEO
Black hat SEO is the term used for unethical or deceptive optimization techniques. This includes Spam, Cloaking, or violating search engine rules in any way. If a search engine discovers a site engaging in black hat SEO it will remove that site from its Index.
Blacklisted
Also known as banned or delisted, a blacklisted site is a URL that has been removed from a search engine’s Index, typically for engaging in Black Hat SEO. Blacklisted sites are ignored by search engines.
Broken Link
Also known as a dead link, a broken link is a link that no longer points to an active destination or Landing Page. Search engines dislike broken links. Keeping all of your site’s links active is an important part of ongoing optimization.
Click Fraud
Click Fraud is the illegal practice of manipulating Cost-Per-Click (CPC) or Pay-Per-Click (PPC) revenue sharing agreements. There are numerous types of click fraud, but in a typical scenario the webmaster of a site that earns money from each click of the advertising links it publishes pays individuals a small fee to click those links. Companies thus pay for advertising to clients who had no intention of buying from them. Some companies have filed class action lawsuits alleging that ad publishers such as Google and Yahoo! have failed to aggressively confront click fraud because they benefit from increased CPC revenue.
Click-Through
Click-through refers to a single instance of a user clicking on an advertising link or site listing and moving to a Landing Page. A higher Click-Through Rate (CTR) is one of the primary goals of Search Engine Optimization.

The Yahoo directory - Free listings for non-commercial sites.
Looksmart (Zeal directory) - Free listings for non-commercial sites
6. Link Building.
When setting up the linking architecture of your site keep in mind that links are of two kinds:
1. Internal links 2. External links
Internal links are the constituent elements of the way your web site is organized. They are the bridges by which one page of your site connects to the other & more importantly outlines, which page of your site will connect to which other page/s.External links on the other hand are the community tools by which the online community votes for you by linking to you. The more popular you get is a function of more incoming links into your website. This in turn is interpreted by search engines as a measure of your online value creation.
To enjoy a good pagerank for the pages it is imperative to have proper linking amongst various pages within the website as well as having good quality external links coming into the page.
A factor to keep in mind while linking is that one should focus on quality links & not always quantity. Consider that, there is a huge difference from a link, to your page from another page with a good pagerank than a page from a low pagerank.

Why is SEO required?
Millions of web pages are included in search engine index. Each search engine process "keyword / phrase" queries more than million of times per day. When searching for any product or service, usually, people go no deeper than 3-4 pages. That's why its important that potential customer (or information seekers) visit your website. If your web page is embedded deep in the search results, it is unlikely that anyone visit your web page. Therefore, you need to improve the visibility of your web site (or web pages contained in your web site).
What is Search Engine Optimization?
SEO stands for Search Engine Optimization. It is a process, in which a web page or a web site is optimized for search engines. By optimization, a search engine such as Google finds the page, includes it in the index, and displays the page when someone is searching for information.
Methods not to be used in SEO
* Hidden text or links.
* Misleading keywords or keyword stuffing.
* Cloaked pages or sneaky or deceptive redirects(keyword-stuffed landing pages that quickly redirect to the real page).
* Doorway pages made only for search engines.
* Duplicate sites or pages.
* Monthly submissions to search engines (a waste of time and money).
* Mainly Optimizing Meta keyword tags (a waste of time and money) but important for some directory listings.

Meta Title Mistakes
SEO is not just a career to those in the business; it is literally a part of every trip through the Internet. A search for anything online frequently has me observing the listings and the sites that rank on the first page results. It can be very interesting to investigate these sites to find clues that could possibly become useful in business. After all, the best way to learn how to rank a website is to observe sites that already rank.
One of things I look at, actually we all look at, are the titles in the search listings. The words and phrases that are displayed in the search listings are pulled from the Meta Title tag in the header of all web page documents. It is this simple Meta tag that many website owners never get right. Below I have listed three of the more common mistakes website owners make with this very important Meta element.
1. Your title Meta tag should never be longer than 62 characters. Google will only display the first 62 characters of any title tag no matter how long you make it. This number varies for other search engines but Google will send over 80% of all traffic to the vast majority of all websites so meeting Google's requirements is most important.
2. Your title Meta tag should NEVER say "homepage" or your website name or address. Unless you are trying to sell homepages, the words "homepage" should never describe your website in the title. The same is true with your web address. Putting your web address in the title tag as a website title waste valuable space that could best be used to target a search word or phrase that can send searchers to your website. Besides, Google already knows your web address, if your site has been indexed.
3. Your title tag should include key words that reflect the theme or topic of that page. Obviously this would include key words you hope to rank for. Using this logic, should you find that you are ranking good for a variation of your desired key words you can greatly improve your rankings for that word or phrase by changing your title tag to include that phrase. This can be desirable if that traffic converts on your website or it could simply be a source for extra traffic that does nothing for your website's profitability.
The title tag is like a name plate pinned to your shirt. It immediately tells those who see it who or what you are. It is the first opportunity to get the searcher to click on your listing. Tying a web page's theme to key words that people search for and then putting those words into your title tag is the most efficient way to get new visitors to your site. After all, that is why we are on the net.
