THE SEO (Search Engine Optimization or SEO) is a set of techniques (more or less complicated and more or less ethical) to improve the position of a website in search engines like Google, Yahoo and Bing. These techniques are designed to give greater visibility to the sites of some very specific types of queries. The visibility of a website on a motion to maximize the number of clicks on the latter. According to one major study, carried out on the basis of shared data error by AOL in 2006, the click through rate on the first position of the natural search results is 42.13%. Specifically, if a site selling shoes, is found in the first position for each user query on the shoes he sells, he generated more traffic than it was in second position and therefore is more likely to succeed to sales. SEO, Google often disrupted by attempting to make any attempt to optimize their algorithm more complicated, constantly evolving and forces responsible SEO adapt each time. In this context, one may wonder how hiring a SEO manager can adapt in the face of search engines, which become more complex over time?
Historically, the SEO has accompanied the birth of the Internet with its first search engines: Yahoo, Lycos, AltaVista and Galaxy in the years 1994-95 and Google three years later in 1998. SEO is considered as a separate activity and becomes a true profession, recognized by all. Given the scale and it takes thousands of internet sites are created every day, specialized agencies SEO will appear to respond to a request for guests looking for a good position for their site. These agencies web marketing will develop efficient techniques for achieving dominate the search positions. These techniques go through the optimization of the site, but also sometimes netlinking by technique a little darker known as the "Black Hat". SEO techniques: between site optimization and Netlinking.
The tasks of SEO revolve around two axes: site optimization (technical and semantic) and the work of popularity (Netlinking). The need for SEO professionals primarily due to poor web design by php developers, Java developers etc that are not aware of these techniques. In this case, the SEO consultant is an optimization of the website.
It performs an analysis of keywords in the website of the client: identification of keywords specific to the company, analysis of keywords competitors use tool to generate keywords and Google analysis estimates traffic with the tool Google keywords. It then ranks these keywords according to their relevance, competition in this word and the estimated search volume. These words are used to enrich the content of your website with keywords quality. The referrer then proceeds to a site audit: audit and technical audit sémantique.L technical audit is to analyze all the elements to ensure that there is no impediment to site indexing by search engines research. The semantics audit identifies opportunities to improve the content and tags, following keyword analysis made previously.
But the biggest piece of SEO involves the netlinking. Netlinking is the development of the number of hyperlinks pointing to a site. If it's links come from high profile site with a page rank indicator (Popularity Google) higher then the site that has the good quality inbound links sees increase its position in search engines. These links are even more important when they are dofollow, that is to say, the link code can be transmitted somehow the page rank of the incoming link. Something that many SEOs take into account in their work. Over time SEO consultants have developed an arsenal to supply links to websites of their clients. Different ways to get inbound links are multiple submit your site in a directory specialized, comment on blogs, forums, partnerships Guest Post (Editor's note: This is the case of this post), Press Releases and other link baiting .
In each case, the referrer will insert a link to its website. He will take care at the same time insert a keyword in the link. By inserting a relevant keyword in the anchor link, the link will boost the incoming position of the latter in the results of search engines. It is therefore understood that the netlinking is a good way to increase these positions if the links are good. It takes time but the result makes up the difficulty.
However, some SEOs have used dubious techniques to boost the positions of some sites. They used techniques Netlinking to rapidly position on certain keywords so unfair request. Concrete instead of feeding a few incoming links a website a week, it will provide hundreds or thousands of incoming links pointing to their site. These techniques are known in question Spam in SEO as Black Hat. Unlike the White Hat is the conduct of a good SEO (website optimization, content and link), and Grey Hat which is somewhere in the middle, the Black Hat methods spammers flooding the web link to his site. To do this, it uses robots working in his place or uses networks of sites dedicated to it.
Faced with these techniques spammers, search engines (especially Google) have countered this by locking the netlinking ways. More updates like Panda (Duplicate glad punished) or Penguin (directories and press release sites reclassified) Google stirred up the SEO industry making it more difficult for the spammers, but at the same time penalizing managers seo. Briefly Google sanctioned everything that did not seem natural and Netlinking with these technical part.
With these updates, Google and other search engines have reduced the bad links in order to reduce technical "webspam." Google now places more importance on the quality and freshness of content available on site, the job of editor web becomes an essential activity to SEO. The goal is to enrich websites, play so moderate on texts rich in keywords and thus gradually increase in research positions.
Social signals from sites such as Facebook, Twitter and Google+ for example, are also becoming increasingly important for SEO experts. Optimizing websites for better natural position is even more important and more difficult than ever. Hire a quality SEO is vital to a successful business on the web.
