Search engine optimization
Linking determines the effectiveness of a website in the eyes of search engines. Primarily referring to connecting a website with other websites linking requires a great deal of effort by search engine optimization companies. An important prerequisite is relevancy. In other words, you should link only with websites having similar products and services. Irrelevant sites do no good, no matter how many number of links you add. For example, if you add a link to a page where the primary key phrase is property sales then ensure that you are linking to similar websites, i.e. property sales. Truly speaking, search engines even penalize irrelevance linking practices and incidences of websites being blacklisted is not uncommon.
The design of a website also accounts for its effectiveness. Fancy graphics, extensive Flash work, images, etc cannot be read by spiders. Hence, it is important that a judicious mix of everything is used. Try to limit any such thing that search engines do not recognize, and try to include those things which increases the chance of your website to rank high. Try to add sufficient SEO friendly content and articles that correspond to the main theme of your website. Current search engine trends give a great deal of emphasis on content among many other things.
SEO companies who emphasize on these steps are the ones who can be termed as seo experts. Remember, ethical seo practices takes time to show results, but once shown, results are permanent. Unethical practices, on the other hand, can give you some first time results, but chances remain that you get blacklisted and disappear from search engines for ever.
