  • url / WeB address The name of the file is part of the URL. Where possible, use keywords in the file name.
  • headings If the keywords are in a heading element then a search engine will know that this page is all about that subject and give it greater weight than other text.
  • text Where possible, it helps to repeat the keywords in the main body of the text at least 2-3 times.
  • link text Use keywords in the text that create links between pages (rather than using generic expressions.
  • image alt text search engines rely on you providing accurate descriptions of images in the alt text. This will also help your images show up in the results of image-based searches .
