SEO Marketing services are immediate, effective and short lived. Whereas another way (directory submission etc.) is one time and continuous process providing long term benefits.

Detailed information about On-page and Off-page optimization techniques is given below:

• Website Content
  
  Content of your site is most important for any search engine marketing. Please assure that your website content is informative and not copied from any other site. Search engines do not like duplicate content. It is impossible to create unique content because words are limited but try to avoid copy paste from any other websites.
  
  
• Webpage Title
  
  Keywords in your title should be relevant to webpage content. Using appropriate keywords in your title will bring more traffic rather than just positioning at number one in search engines' ranking. Put your main keywords at the beginning of your page title. Title must contain main keywords as well as describe webpage contents and attract users to click on it. Make the title short (about 55 to 60 characters). Do not start webpage title with your company name unless and until you are a well known company or represent a brand.
  
  
• Meta Tags
  
  Two important Meta tags are KEYWORDS and DESCRIPTION. Meta KEYWORDS tag is not as much as important as DESCRIPTION. Generally search engines ignore the Meta keywords, but Meta DESCRIPTION is important. Meta DESCRIPTION length should not be less than 30 words. Use main keywords in your Meta DESCRIPTION, but keep it in your minds that Meta DESCRIPTION must not be mere a group of keywords.
  
  
• Heading tags
  
  HTML <h1> to <h6> Tags should be used at the time of content writing . <h1> tag is the most prominent from the other tags. Search engines easily understand these tags and give importance to those words within these tags. It is our suggestion that each web page must contain at least one <h1> tag. Please do not throw anything into the <h1> tags.
  
  
• Keyword Density
  
  What is keyword density? Keyword density of a word is the percentage of occurrences of a word to the total number of words on that webpage. Good keyword density will help to better position the site in search engines. Keyword density should not be greater than 5%.
  
  
• URL Structure
  
  It also important aspect of search engine optimization that URL of a webpage should contain main search keywords. There are various methods to make this work, such as mod_rewrite on apache.
  
  
• Sitemap
  
  It is always a good idea to help search engines to find the content on your site. Sitemap helps search engine robots to find all pages in your site and index them. Google, Yahoo, MSN and Ask all support sitemaps. Most of the time you can simply name it sitemap.xml and the search engines' robot will find the file easily.
  
  
• Internal Linking
  
  Internal linking is important for the purpose of search engine optimization. Internal linking helps robots and visitors to navigate or find content on your website. Internal linking in your website can make a huge impact on your site ranking in various search engines. Make sure that all your internal pages link to your homepage. Use <nofollow> tag if you want that a particular page should not be indexed in search engines. Ranking of your website depends on website content and search interests.
  
  
• Domain Name & Age
  
  Domain name is also a part of your URL of your webpage. It will help if your domain name contains main keywords of your business but it is not that important. One of important factors that play key role to achieve good ranking in search engines is the age of your domain.
  
  
• Incoming Links / External Linking
  
  Incoming Links or External Linking is most important to boost your ranking. Quality external pages link, is the prominent way to achieve good ranking in search engines.
