Are there different types of SEM ?
Yes, essentially SEM is of two types.
In the first, the consultant will have to change the web site ( called search engine optimization or SEO for brevity) for doing proper SEM work. Thereafter the site has to be continuously interlinked with best of other online resources. This will ensure good editorial listings for the site.
Typically this work takes 6 to 8 months to produce stable & lasting results.
A shorter yet paid way of promoting a site with search engines is Pay per Click(PPC). In this SEM campaign, you can bid on your search phrases & when those phrases are searched, your advertisement will appear on the results page. Once some one clicks on your ad, the bid amount is deducted from your account.

A good SEM campaign is a means to an end. It can get your site to rank well for your business search terms. However the sales & revenues on your site are driven entirely by the user experience & the business merits.
SEM gets the traffic. Site has to sell.

To achieve deeper indexing & a better ranking the SEM starts at the level of web design. When one is conceiving of creating a business presence online he has to keep two factors in mind:
User experience in navigating the site.

These two users will see different pictures of the same site. The human user will see the browser supported, colorful front end. The spider( software, search engines send to crawl the web for information) will see only the text on the site.
So different strategies need to be adopted for each set of users. As web designers are engaged for formulating the site for end users, simultaneously, SEM consultant should figure in to optimize the site for spiders.
