Currently the use of mobile phones to surf the web is being developed with greater importance by users and its growth is increasingly high in our country. Search engine positioning has changed a lot in recent years. It has gone from an indexing allowing the most visible contents to become the ones that took better advantage of the algorithm in their favor, in an era in which positioning responds to an obsession to provide service to the users It is a field that started from the moment that search engines won over the first directories at the beginning of this century. From the first moment, a permanent war was created between the interests of the search engines (to show the best content) and those of the developers (to position their web). As search engines, and especially Google, got more data about user behavior and searches, they refined their algorithms. At the same time, SEOs tried to develop techniques to manipulate their results. Currently, SEO is adapted to the day-to-day life of users. The aim is to help them to relate more easily to the world, with an indexing process that is increasingly similar to that of human judgement. The aim of our research is: To evaluate the Mobile Web Positioning in Panamanian companies and Institutions' websites. For the development of this study we used the following method that consisted of four (4) stages. The first stage, literature review, about mobile web positioning. The second stage, selection, evaluation and elaboration of a list of tools. For the third stage, the selected sites will be evaluated, using the online computer tool The fourth stage is the tabulation of the information obtained. As a result, the mobile accessibility continues to grow in our country and the SEO MOBILE is mandatory and in Panama, despite the fact that its development is growing every day, not all websites have a page optimized with the Seo Mobile and if they do, it is not optimized in an adequate way with the necessary standards to have one of the main positions in the search engines. In order to improve themobile web positioning and obtain an adequate performance of the website, it is essential to use the mobile SEO tools, since they are fundamental because they help to analyze the state of the web pages and to provide indications about what we should improve.
