Frequently Asked Questions

If you want your website to serve to get clients, you need a website optimized for SEO. As an SEO agency in Terrassa, we take care of optimizing your website so that you maximize your Google ranking.

However, it's not always necessary to invest a monthly amount in SEO positioning. It depends solely on the competitiveness of your keywords. In less competitive terms, to rank in the top 5 results, it's sufficient to have good code and texts that use keywords. In highly competitive terms, on-page SEO optimization must be accompanied by building a network of backlinks to increase domain authority, and this does involve a monthly investment.

During the keyword study, we select those that generate the best opportunities and, based on your available marketing budget, we jointly develop a strategy to make your website a reference for Google.

Any investment in SEO positioning takes a few weeks to take effect. Google gradually trusts new websites or major changes. It's common for it to take up to 3 months for the new web positioning to stabilize.

Once the SEO positioning has stabilized, the results are maintained for years. So, investing in SEO is effective in the medium and long term. But if you need to increase your traffic for a specific period, it's necessary to resort to SEM positioning strategies through Google Ads.

As an SEO agency in Terrassa, we maximize the results of your investment in SEO so that you rank at the top as soon as possible.

A blog allows you to create articles periodically and position new keywords, so yes, a blog helps you improve SEO in Terrassa and in any city.

That's why we recommend that your website be built on WordPress, as improving SEO positioning on WordPress is very simple.

A blog also facilitates the generation of natural backlinks, strengthening domain authority and improving its position in search results.

As an SEO agency in Terrassa, we provide you with monthly reports so that you can verify that both web positioning and web traffic are improving day by day.

Thanks to Google Search Console, we can continuously monitor variations in the positioning of your keywords.
