Search engine marketing (SEM) - is a new SEO.
Search engine marketing (marketing through search engines, Search engine marketing, SEM) meant by a fee for visitors (clicks). Search engine optimization (search engine optimization, Search engine optimization, SEO) is the means by getting traffic directly from search engines. These two facts are based on a popular myth: it is better to get users once spent on SEO, than constantly getting new users, but the weekly cost (by SEM).
There are many reasons to doubt this statement. Let's look at one example - the difference is Landing page (landing page). We first define what it is? Landing page - a resource on the topics that are being transferred when visitors click on any link (for example, in the contextual advertising). For example, you advertise the event and bind the reference to the cost of the event, here's the page and will be landing page.
In SEM, you can specify the page itself, to which you wish to have got a visitor. If we look at SEO, then the search engines themselves are (rank) on the page that will be tossing the visitor. That is, it turns out that using SEO is very difficult to send a visitor to the required part of the resource.
If your landing page is optimized for specific keywords, then it can more accurately determine the correct information and advertising, which is looking for a user (ie, the visitor will go exactly where you want it passed.) But we need to know that the page must be information that the visitor is looking for, but not the information you want to see a visitor. Otherwise, the user goes to your site.
In both cases, SEO and SEM comes down to the monetization of traffic (visitors). SEM firms may require a higher investment of money in the initial stage than the SEO firm (as in SEM you pay for project management and the deployment of contextual online advertising, while only in the SEO project management), but most likely you will get bigger and a rapid influx of visitors by using SEM, and therefore you perekonvertiruete traffic into money (monetiziruete traffic).
If you look on the other hand a good SEO indispensable factor for the advertising on the Internet, but to say that SEO is better in terms of profitability than the SEM, we can not say, because from SEO is free traffic, and there is the most important advantages of SEM: control traffic. And it is this control allows you to see the difference between getting traffic and monetize.
In simple terms: when you get a SEM deliberately targeted traffic, and if SEO is not all traffic is targeted, so if other conditions visitors, attracted by SEM will provide much greater benefit than the visitors who came through SEO, SEM but the means by itself a significant cost.
The optimum is still holding together SEO and SEM.
Here it is the difference between SEO and SEM.
The choice is up everyone!...
