Wordpress platforms All In One SEO Questions

I have a query about the All In One SEO plug-in for Wordpress platforms. How many search phrases do you use for your primary web page, other webpages and blogs? Do you use more wide search phrases such as Vehicles or do you use more actual search phrases such as 2005 Red F150 Vehicle (just an example)

Do you use the same search phrases for every web page or do you modify them up in accordance with the page?

Also, same query for pictures on your site. How many search phrases do you make the picture title?

Also, what do you do for Headline Feature and Selection Label?

Thanks so much

PS- This is for my local website that im trying to achieve greater rankings in my area and a several other significant places im within 100 kilometers of.
