Hi there,
Some of my basic tips include..
*images: adding alt tags and descriptions
*Titles: have 60 characters for SEO titles.
ALL must include your keyword/s.

Content
Have transition words in your content on your website pages and make sure its comprehended correctly – getting a copyrighter to do this can be ideal.
Don’t start sentences with the same word.Try to mix things up!
Write as passive.
Include internal links – links which are pages on your website, example linking your contact page in.
Include external links – links which are to websites not your own, example linking your google business profile. (https://www.google.com/business/)

Thank you
