Semantic code

H1~h6 tags more for headings

UL tags for unordered lists

OL label more for ordered list

DL tags are used to define data lists

EM, strong to emphasize

<a> tags

<p> tags and <br> tags (for text spaces only)

Defining tables with Caption

labels should use ALT to explain

<strong> used to emphasize,<em> for italics and <b><i> labels

Important content HTML code on the front

Important content do not use JS output

Use the IFRAME framework as little as possible

careful use of display:none; (Search engine will automatically filter out, the spider will ignore the content here)

The more streamlined the code, the better the clearer the better (the hierarchy of more than three layers of spiders do not want to climb again)

The number of home links (small and medium-sized sites within 100, page navigation, bottom navigation, anchor links, etc.)
