Online marketing has never been as important as today. Think for a minute if people do an internet search, and your company does not appear: how do you intend to stop buying products from your competition? Currently, we have several ways to draw attention on the Internet. There are many users who access the Internet at the time of deciding to purchase a product, which undoubtedly will lead to your website. When it comes to searching through the search engines, the most relevant are Google, Yahoo and Bing (in that order) and then there are the others who have lower market share. There are two ways to get noticed in the search engines. Online advertising- SEM. SEO: Search Engine Optimization or SEO Services. The word isn?t so familiar with online advertising- massively- but when using a search engine, we present a SERP (a page with search results) of the phrase or word you searched. Links presented in a narrow column to the right of the search results. There are occasions where the results can also be found at the top before the organic results. If we look carefully we will see that before the results Google shows us that these ads are payments or are sponsored. Online advertising is linked to organic techniques, which are gaining popularity. If the category you seek has several advertisers, Google gives you the ability to view more ads. These ads work like an auction, one advertiser who bid a higher amount of money for your ad (with that keyword) appears first and so on. Each time a person clicks on the ad, this is redirected to the advertiser's website and the cost per click is deducted from that advertiser's daily budget. The SEO, on the other hand, refers to techniques used to get a site listed in the top locations when searching with certain phrase or keyword. These results are known as organic or natural results. Updates are taking place and this requires plenty of effort. Google does not receive any payment for the placement of these results. The ranking that a website is positioned corresponding to a certain algorithm (unknown) specific to each search engine. The higher the web is positioned in the ranking the greater the traffic that you will receive on its jurisdiction. I think this post has helped to refresh your mind about SEO.
