A good SEO job has a cost , since, as I said before, positioning yourself on the first page of Google requires work and an investment of significant time. Investment in SEO usually has greater profitability if you look at the project in the long term. Reaching the first organic positions of Google will cause page visits to be high. An investment will have been made to position the page there but it will not be necessary to pay for each click obtained. It must be clear that, as in the case of SEM, in sectors with higher competition, the price for positioning a page in the top positions of Google will be higher than in projects with low competition.
As with SEM, there will be companies that cannot afford the necessary investment in SEO in their marketing plan to reach the top of the search engines fax list for their most important keywords. Visibility over time As you can imagine, the visits achieved thanks to SEM campaigns stop occurring the moment you stop investing in them. SEO tends to last over time, if you stop investing in SEO you will not suddenly lose all visits. Your website will tend to lose positions but, just as it took a while to get to the top, this decline will also be gradual and the speed also depends on the work that the competing websites do to position themselves.

Target audiences It can be thought that the target audience is the same with both actions, since in both cases the results will appear on the same Google page. However there are small variations on this. There are some people who do not know the difference between SEO and SEM, so they will click on the first results they find, that is, on the ads. The first results in Google will always be reserved for ads. We can find up to 3 results of this type in Google. If a potential client does not know the difference and only compares between 3 results, even if our page is the first in SEO positioning , we will not get that visit.
