Monthly SEO Plan Development {LOCAL Monthly Retainer}

How is everyone!
I have an seo client that i was contracted just to do on page corrections. I really want them to turn into a monthly client but not sure on what I can do past optimizing their site? Back links? Content? What does everyone perform on a monthly basis that will increase page ranking and that you can send to the client to let them know what your doing? Thanks

If the content is less, add some more content including some keywords and add some headings including the main keyword

Do the proper onpage

Include the schema markup

Add the website in Google webmaster and submit the sitemap

Point some web 2.0 backlinks and some good quality backlinks like niche relevant guest posts

Do the complete SEO Audit of whole website from some tools

And give the proper report to the clients

The client will be happy and surely give you another month plan

That's great advice. Once I get the new monthly plan then what do I offer? More content, back links, blogs
