So who wins in SEO vs. SEM, check it out!

SEM or Search Engine Marketing 

This one uses paid resources to gain visibility in any search engine. When you perform a search, the first result will include the word AD, meaning that this brand or business is paying to appear at the beginning of any search results. This strategy can consist of not only the different activities associated with the multiple ads but also the budget that will pay the placements for each ad.

SEO vs. SEM: differences

Even when we talk about how both are necessary for a great search marketing strategy, they present some differences that you must know before diving into this world. Check out SEO vs. SEM with the following table.




Search Results Lists

The results using SEM will appear with the word AD in some part of the text, indicating that it is a paid result. SEO is working with organic techniques so that it won’t appear with this tag. 


SEM needs a budget for placements. This means that each time a user clicks on the link, you must pay for that. SEO doesn’t need a budget for its placement. Brands earn their place in the search engine using keywords and other methods. 
Visibility Brands use SEM to reach exactly their target audience, one that has already been defined.

Instead, with SEO, even when the brand knows their target audience, cannot reach their target audience, it will appear to anyone that uses the keyword. 


As with any strategy, results are highly important, and one of the best benefits of paid plans is the quick results.

SEO takes time. After all, it is organic and their result will reach the goals with lots of patience.

Testing With SEM, you can turn on and turn off the ads whenever you need. This is perfect for running different tests over changes and styles.

SEO keeps the same style and content for a longer time, and it is hard to make big changes. It’s better to wait for established results before starting to make changes.

Value Over Time

SEM is a paid strategy, and when the budget is over, it’s also the strategy. Normally this type is used just for a short period.

SEO values time and growth in it. A solid strategy will show how the time will present the best result and loyal traffic.  

Click-through rate With SEM, it is obvious that you will get CTR, but normally people tend not to trust all in those ads.
