The short answer is yes- but often when a SEO company does this they refer to top placement for a keyword that is non-competitive such as a company name. The question should really be Should SEO companies guarantee top placement in search engines? The answer is no. For instance a business wishing to be ranked top for a keyword such as accommodation should not be promised top placement on the search engines. The reason being: a) The top ranked web site for this keyword has thousands of pages indexed by the search engines and also has hundreds of thousands of inbound links. To compete with this #1 ranked web site is virtually impossible, would take years to compete with this and take many, many hours of work and link building. b) SEO companies have no control over the policies of search engines. To guarantee a top placement is impossible because ultimately the SEO company has no control over how search engines index web sites and no control over changes in the search engines algorithms.
As far as I know, good SEO companies in UK do not focus on the first positions, while there are more important KPI metrics. For example, increasing the percentage of conversions, and increasing sales, traffic, and visibility of your project. This is more important and effective for business than just the value of the first position for a keyword.
