   SEO is an organic method of making a search engine friendly website. SEO is a set of practices to make the website and its contents noteworthy and visible to both the search engines and the web users.

   SEO helps increasing a websites visibility within the search engines. This can be achieved by displaying the website on the first or second page of search engine results page (SERPs)

2. Concepts and Description

   1. Page Rank

      It is an algorithm used by Google, which assigns numerical weight to the URL of web documents to measure their relevance. Google had published their page rank formula which is stated below:

      PR(A) = (1-d) + d(PR(t1)/C(t1) + +

      PR(tn)/C(tn))

      PR(A) -Page Rank of the page

      1-d-d is a damping factor considered to be about 0.85

      PR(t1) -t1 is the PR of the incoming link page

      PR (tn) – is the Page Rank of all of the linking pages.

   2. Crawler and Database

      It is a program that sieves through text on websites to study the information contained in it.

      A web directory is a directory on the World Wide Web. It specializes in linking to other web sites and categorizing those links. Web directories allow site owners to directly submit their site for inclusion, and have editors review submissions for fitness

3. Search engine Anatomy[1]

   There are four parts in a search engine, observed upon query insertion. The engine also indicates how many results it has fetched and in how much duration.

   i. Non sponsored listing

   These are the results from the listings that are done by Google crawlers according to their ranking algorithm.

   Sponsored Listing

   Sponsored listings are a set of results shown in the result page at the top most and the right corner.

   Search box

   This section is used by the user for his query; it may be from his country or from World Wide Web.

   As one start typing his query in Google, it starts displaying result by analyzing each word.

4. Working of Search Engine[2]

   Following are the various steps in the working of Search Engine.

   1. Crawler

      It is a program, which sieves through text on websites to the information contained in it. SEs visits the web or sieve through text on the web pages to see the information contained in it using the program named Spider or Crawler. The frequency of crawling is not predictable.

   2. Indexing

      Information about web pages are stored in an index database for use in later queries.

   3. Processing

      Search Engines do not examine the entire web when a user enters in a search query. SE simply gathers information according to the search words the user has entered.

   4. Relevancy Calculation

      The web pages are assigned certain weights based on page ranking algorithms. The algorithms use mathematical equations to rank them.

   5. Retrieving the result

      The search results are displayed, sorted from the most relevant to the least relevant sites, in page wise manner.

5. Method Proposed

The method proposed for performing SEO contains the following steps.

1. Search Engine Submission

   • The first step is submitting the websites homepage. It should be done along with submission of a site map since it has direct links to the rest of the website. This will help search engines to find your complete website.[2]

   • Place of Submission:

   o It is recommended to submit your home page to the major search engines individually, at least initially:

   1. Submit to Google

   2. Submit to Yahoo

   3. Submit to MSN

2. Directory Submission

A web directory classifies links into categories and subcategories. After validation your link is listed in the directory. The search engine thereby acknowledges your presence in the directory than some other website.

            Frequency of keyword to be optimized must be 3%-5% on the pages with 500-700 words & 8%-10% on the pages with 700+keywords.

3. SEO in Web application

   A web application is characterized into 2 categories based on the content it holds. Depending on this content it is categorized as static or a dynamic web application.

   1. Static Website

      A static website can be thought of as an online brochure. It acts and feels like a printed brochure you can view through your computer screen.

      • Dynamic Website: Websites that utilize databases, which can insert content into a webpage by way of a dynamic script like PHP or JavaScript, are as considered dynamic.

      • It is less time consuming in comparison to static websites and can be done easily without much technical support.

   2. Dynamic URL

A dynamic URL is the one which is a result of a search within a website driven by a database running on some script. When a sites database is queried it results in generation of a dynamic URL.

1. Static Vs. Dynamic

   • Static URLs are generally ranked fairer in search engine results, primarily because they are indexed faster than dynamic URLs.

   • Dynamic pages generally do not have keywords embedded in URLs, while it is strongly recommended to have URLs, which are rich in keywords.

   • Dynamic URLs are less friendly to search engines.

   • The table given below summarizes the advantages and disadvantages of using static URLs opposite to dynamic URLs in context of SEO.

Solution to the Dynamic URL problem

1. URL Redirect

   Redirection is the process of forwarding one URL to a different URL. A redirect is a way to send both users and search engines to a different URL from the one they originally requested. Below are descriptions of some of the commonly used types of redirects.

   • Types of Redirects

     1. 301 Moved permanently

        A 301 redirect is a permanent redirect, which passes between 90-99% of ranking power to the redirected page. It is the best method for implementing redirects on a website.

     2. 302 found (HTTP 1.1)/ MovVedol.T2eIsmsupeo1r1a, Nriolvyember – 2013

        (HTTP 1.0)

        It is a temporary redirect. It passes 0% of ranking power and in most cases should not be used.

     3. 307 Moved Temporarily(HTTP 1.1 Only)

        This redirect is the HTTP 1.1 successor of the 302 redirect. While major crawlers will treat it like a 302 in some cases, it is best to use a 301 in most cases.

     4. Meta Refresh

     Meta refreshes are a type redirect executed on the page level rather than server level and not recommended for SEO technique

2. URL Rewriting

URL rewriting is masking the dynamic URLs with static ones .This means that the URLs that previously contained query strings with elements such as ?,+.&,= or % will contain the more search engine friendly / (slash) element and present themselves in a simplified form.

Example

Dynamic URL (Before Writing): http://www.companyname.com/products/items.p hp?id=x&model=y&variety=z

Static URL (After Writing): http://www.compantname.com/x/y/z.html

1. Dynamic Content and SEO

   SEO for dynamic content poses a few significant challenges.:

   1. Challenges for Optimizing Dynamic Content

      1. A Dynamic URL

         A Dynamic URL is an address of a dynamic web page. Dynamic URLs are fairly cryptic in their appearance.

      2. Login and other forms:

      Login forms can restrict access to pages not only to users, but also search engines.

      Cookies:

      Web cookies are small bits of data that are stored Pages that require cookies can block spiders because spiders don't store cookies as web browsers do.

      Hidden pages:

      Sometimes, pages on a website are hidden from search engines because they're buried too deep in a site's architecture. For example, a page more than three clicks deep from the home page of a website may not be crawled without an XML sitemap.

      d. JavaScript:

      Search engines don't index content that requires full-featured JavaScript. Text that is created using JavaScript will only be accessible with JavaScript enabled, will not be indexed.

   2. Optimization of Dynamic Content [4]

   1. Creating static URLs

      Dynamic URLs, especially dynamic URLs with vague names, can be a turnoff to searchers. In order to have friendly URLs, you want to rewrite your dynamic URLs as static URLs. Blogs powered by wordpress or Blogger make it easy to convert dynamic links to static links.

   2. Optimizing content hidden by forms

   If you want your form's hidden content to be indexed, make sure to give access to it in ways other than through a form alone. If you have content that you want indexed hidden in a login- only area, consider taking that content out of the

   restricted area so it can be indeVxeold. 2. Issue 11, November – 2013
