What is the component name?
May be they mean this:
procedure TForm1.Button1Click(Sender: TObject);
begin
  showmessage(inttostr(x and 255)); // x is your byte
end;

But it's true, reading "PageRank.Rank" will get you incorrect number in comparison to the actual rank that you should get, and as the component read-me suggested use "PageRank.Rank and 255" to get the actual rank as it appears in google page.
After you ensure successfully connecting, you can use this:
showmessage(inttostr(PageRank.Rank and 255));

Open in new window

For example reading EE rank will get 262 so to get the actual rank you have to make it:
262 and 255 which equals to 6.
