When we enter a search engine like Google and do a search for something (a keyword), a list of sites considered relevant to answer your search is displayed, related to that keyword you entered in the field.
Through the SEO service we can make your site appear at the top of this list, on the first page of Google, for example.
Financially, it’s easy to see that increasing your site’s visibility on this list will increase your chance of getting more customers. Therefore, SEO serves to increase ROI as well.
We can say that a complete SEO consultancy is divided into modules, which work in cycles:
The right implementation of the 3 modules will increase your digital presence, making your project more relevant in the online environment, making your website, your brand and your products or services appear more frequently in Google results and also in others search sites.
There are many reasons to invest in SEO, but one stands out above the rest:
Today, it’s no longer enough to simply exist online — your website needs to stand out. Visibility is what drives sales and builds brand awareness.
Through strategic SEO, your website, blog, or online platform can attract a growing stream of highly qualified visitors, leading to increased brand recognition, authority, and long-term business growth.
Unlike paid ads, SEO delivers lasting results. It’s a cost-effective way to boost your online presence organically — allowing your business to grow without constantly spending on advertising.
An SEO audit is a comprehensive analysis that identifies critical issues affecting your website’s page optimization, technical performance, and server configuration.
This process goes beyond your site’s internal structure. A complete SEO audit also evaluates external factors essential for your digital visibility — such as backlink quality, anchor text distribution, indexed pages, and even your competitors’ positioning in search engines.
By understanding both the technical and strategic aspects of your SEO, you gain valuable insights to improve your rankings and online authority.
When we go to a search engine and search for a subject (word or phrase), we receive as a result a list of sites considered relevant to the search.
The text you type in the search field is what we call the keyword or keyword phrase.
Upon receiving the search request, Google (or any other search site) searches its own database to see which pages have the best answers to that search performed by the user.
It then displays the results on the search page, ranked from best to least relevant.
There are hundreds of factors that can make your site and pages relevant, meaning pages that are useful enough to display as a result of a search.
The SEO Service and Google Ads Service serves exactly to make your site appear on the first page of Google.
