| Inbound Links:` |
| The links from other web pages are inbound links. There are good links and bad links. Good links are those which are ranked highly by the search engines and are relevant to the users search. Bad links are those which are banned by the search engines and are not relevant to the content of user’s search [11]. |

| There is an anchor tag with which the hyperlinks from one web page to another are given. Search Engine decides the rank of these web pages which are interlinked by the numbers assigned to these web pages. If one web page or web site is more popular to prospective customers then another web site link can be added to the popular website to get some favour of it [1]. If the web pages are interlinked then all these web pages are crawled, ranked and stored in the database respectively. |
| There are off page ranking factors and on page ranking factors. On Page factors are title tags, header tags, alt image tags, content, keyword frequency etc. The off page factors are link popularity, anchor text etc [8]. |
SEO TRENDS |
 |
| Humanized Ranking: |
| According to Panda and Penguin updates SEO trend ‘humanized ranking’, search engines are much dependent upon humans for page ranking purpose. This way, humans act as the quality testers for search engines. Google is already using such factors for more real time search [9]. Second aspect is of social networks used by humans which contribute to improve ranking of web pages. |
| Quality and not Quantity: |
| This trend in SEO is known for the most relevant and better results in response to the user query. Quality trend of the SEO aims at freshness of the content; quality of the content must be good enough to satisfy the user’s search via the search engine [9]. Example – In Google, panda2 focuses on the quality and the freshness of the content. |
| Voice Search: |
| According to Panda and Penguin updates the ‘voice search’ is more useful for fast searching on the World Wide Web. |
| Instead of browsing on the web, humans are looking for the direct answers in response to their query [9]. Instead of writing their query in the search box they can find results relevant to their question with the help of voice search trend used in search engine optimization (SEO). |
| Mobile Search: |
| In SEO 2012 one can expect of huge features in the mobile search market. Mobile search can be done while talking to your phone, or using the social networking websites, or by tapping a search into your phone. It may be the biggest search medium [9]. |
| Title Tag and Headings: |
| The title tags are very important. A website developer should be able to define the given topic or with which the website is related to in a manner that it seems to the user to be a useful link. Title link excites the user and makes the user to click on that particular link of website. |
| The search engines give importance to the heading tags. Heading of the topic is relevant to its description [9]. It makes some logical sense for an article to split up into different parts. |
| Personalized Search: |
| The SEO trend ‘Personalized Search’ has been updated by post Panda and Penguin. More changes in rankings can be expected from the personalized search. Example - Using social networking, more changes in ranking and personalized search have occurred. [9]. |
| Social Media: |
| In 2012 the search engine optimizations became more of the social media optimizers (SMO’s) [9]. In the social media instead of just focusing on the page factors of the search engine optimization, it also focuses on the social integration. |
| Link Building Techniques: |
| The authority of the web pages is measured by the web pages stored in search engines’ database and further through the links from these web pages. Example - Search engine Google uses Page Rank algorithm to rank the web pages and decide the position of the web pages which increases their importance [9]. |
CONTENTS OF SEO |
| The search engine optimization focuses on search engine marketing that helps website rank higher in the natural results or paid search [3]. A search engine contains the crawler or spider that downloads the web pages. For the storage of downloaded and processed pages, database is used. The result engine is used to extract the web pages from the database. The web server is responsible for the interaction between the user and search engine components [8]. |
| The results are retrieved and displayed to the user by sorting from most relevant to least relevant web sites [8]. |
IMPORTANCE OF SEO |
| The Search Engine Optimization is much important for making the web sites popular by bringing the relevant websites in notice of the prospective customers [8]. SEO is the most effective website marketing tool. Example - Google is the search engine used to make searching easier for the user and maintaining the websites rank higher by displaying the links of most relevant web pages at the top of the list. Usually normal user accesses the web pages that are shown at the top of the list. The Google search result position is shown in a figure 3. |
 |
WORKING OF SEO |
| The web spider crawl the web pages and builds a list of words location then indexes them and stores the data in database for user access [2]. |
 |
| The result engine extracts the results from the database and displays it to the user as most relevant web pages to the user query. |
| When user types something in the search engine box the search engine processes the user request by matching the user query with the results stored in the database. The results are stored in the database in the form of web pages. These web pages are ranked on the basis of content of the web page, relevant keywords used in the web pages, the frequency of occurring of keywords in the web page [2]. If the title, description, content of the web page is more relevant and important then web pages are listed at the top. Description of website is given as the summary. The title or description of the web sites should appear to user as the useful link [8]. The users normally visit or attempt to click on the web pages that are given at the top. |
| The web pages are ranked on basis of the numbers assigned to these web pages. The web pages are stored in the database and retrieved with help of result engine. Results are displayed on the user screen in the form of a list from the most relevant to least relevant web sites[3]. |

CONCLUSION |
| Search engine optimization (SEO) has evolved from search engine marketing (SEM). Without the help of search engine (to search anything) the user will have to remember almost all URLs exactly. It is very difficult and searching will become for the user. To accomplish this task and to provide the best results to the prospective customers (users) the search engine optimization is done. SEO uses page ranking algorithms for providing best relevant results to the users for every search query. Page ranking is done by a powerful web marketing technique known as Search Engine Optimization (SEO). SEO uses techniques such as black hat technique, white hat technique. White Hat technique is more effective as it follows the search engine guidelines. Data is visible while using white hat technique as it focuses both on search engine and the searcher both. |
| SEO is the effective website marketing tool. To make web sites popular among the users, the web site can be synchronized with the social networking web sites and by interlinking your web site with popular web sites. The rank of those web sites will rise and will be shown at the top of the list when user makes a search. The complexity of page ranking algorithms are O (log N), <O (log N). Ranking is based on various factors -on page factors and off page factors. On page factors are title tags, header tags, alt image tags, content, hyperlinks, and keyword frequency. The off page factors are link popularity and anchor tags. SEO is a technique used as a part of SEM. Website without SEO is just like a shop without salesman. |
