If I mark or put a simple wordpress empty page aor anything without content and and do massive backling and then load the content . Will it work or not mean the backlink will work or not if there is no onpage seo or no content what happens . Its for a client he want about 3 month of work done for a site , but dont want to put content yet , might be after a month . Example : let say i do directories submission for a domain , thats indexed but no relavent content . Whats you thinking , will google devalue the link juice.
