Often we receive requests "I can not find my page on Google", without giving us a hint, what exactly was searched for, to find the own, mostly free homepage. For example, if your site is about pets and you enter pets in the Google search, then of course there should be something about pets on your homepage.
It brings only conditionally something, if you treat on your web page the topic dogs, cats, hamsters, rabbits or the like, but nowhere also only approximately the search word "pet" appears. Because search engines can only "read" what is on the pages of your homepage and if "pet" does not appear anywhere, then you will hardly be found with your page in the Google search with "pet".
You should also make sure that you provide the search engines with enough "reading material". With only one sentence on your web page Google will classify your page as relatively uninteresting and you will end up somewhere in the nothingness of the search results. A recommendation of the number of words on a single (sub)page is at least 300 words, although a maximum number should not be exceeded, so that your "real" website visitors do not have to scroll through the content of your page bored. Here, various online experiments show that the reader's intake limit is around 1000 - 1500 words, depending on how interesting a topic is designed.
