search engine optimization dubai


SEO strategies vary widely, in accordance with a specific site's need. Broadly speaking, SEO may be geared towards increasing either, or both, the total number and quality of visitors from Search Engines, with a quality visitor measured by how often a visitor using a specific keyword leads to a desired conversion action, such as making a purchase or requesting further information.

Search engine optimization can be offered as a stand-alone service or as a part of a larger marketing effort. As part of SEO deals with making changes to the source code of a site, it is often most effective when incorporated into the initial development and design of a site, leading to the use of the term Search Engine Friendly to describe Content management systems and shopping carts that can be optimised easily or effectively.

There are a range of strategies and techniques that can be employed in SEO, including changes to a site's code (referred to as "on page factors") and getting links from other sites (referred to as "off page factors"). These techinques can be put into two broad categogries: techniques that Search Engines either do not approve of, referred to as spamdexing, or attempt to minimise the impact of, and those techniques that search engines either have no issue with, or are simply part of good design.

Some commentators, and even some SEOs, classify these methods, and the practitioners who utilise them, as either "white hat SEO" (methods generally approved by search engines, such as building content and improving site quality), or "black hat SEO" (tricks such as cloaking and spamdexing that Search Engines do not universally approve of).Other SEOs reject the black and white hat dichotomy as an over-simplification.

SEO, as a marketing strategy, can often generate a good return. However, as the search engines are not paid for the traffic it sends from organic search, the algorithms used can and do change and there are many problems that can cause a Search Engine problems when crawling or ranking a site's pages, there are no guarantees of success, either in the short or long term. Due to this lack of guarantees and certainty, SEO is often compared to traditional Public Relations (PR), with PPC advertising closer to traditional advertising.

Today, most search engines keep their methods and ranking algorithms secret, to compete for finding the most valuable search-results and to deter spam pages from clogging those results. A search engine may use hundreds of factors in ranking the listings on its SERPs; the factors themselves and the weight each carries may change continually. Algorithms can differ widely: a web page that ranks #1 in a particular search engine could rank #200 in another search engine.

Google, Yahoo, Microsoft and Ask.com do not disclose the algorithms they use to rank pages. Some SEOs have carried out controlled experiments to gauge the effects of different approaches to search optimization. Based on these experiments, often shared through online forums and blogs, professional SEOs form a consensus on what methods work best.

SEOs widely agree that the top signals that influence a page's rankings include:

  1. Keywords in the title tag.
  2. Keywords in links pointing to the page.
  3. Keywords appearing in visible text.
  4. Link popularity (PageRank for Google) of the page.
In addition, there are many other signals that can affect a page's ranking
