If you are starting a new site, or even auditing an current site, then you might not have yet considered the pages of your site other than your posts. But, there should be a few practically standard pages. Here are my suggestions and reasons.
A Home Page - On the whole, it is nice-looking obvious that you are going to have a home page. Most sites will display recent posts either in full or merely as excepts. But, if you are intending to sell posts, then you really should include the full posts to give advertisers full value, and increase your advertising fees.
Contact Page - You might not think that a contact page is a necessary part of a weblog, but it is totally important and should not be excluded! It is vital to have a contact page if you are wanting to run any sort ofadvertising at all, or to communicate with others who might be interested in your activities.
Displaying your phone number and address is possibly far from ideal and displaying your email address opens you to all sorts of spam, but a simple contact page with a contact form is simple enough. Have a look at the newsletter plugins and even captcha form plugins that are available for this.
Why is it indispensable? Well, once your blog is doing well advertisers may find it and want to ask you around buying space. Other bloggers may want to contact you around guest post opportunities on your site. Having several way of contacting you is invaluable.
Disclosure Page - Merely needed if you are making an income in several way from your site, if you are affiliate selling, sponsored posting or a variety of other paid methods, disclosing that this takes place is a good idea. Only say that you do accept payment for posts and so on.
Subscribe Page - This is another one you might think is pointless, but is actually very useful. You might have a big, straightforward to use RSS icon on every page, but does every reader of your site know how to use it and what the advantages are?
Create an obvious page, that can be called Follow Us, Read More or something fairly obvious to indicate that it is the page to go to in order to find out more about what you are writing. Give on this links to your RSS feed, plus a comment on the advantages on using RSS Feeds. Sell it to your readers, if they have got to this page rather than using your RSS icon, then they perhaps need help.
Then either add instructions on how to use the RSS feed or a link to a site that explains it. Some readers could be so pleased to learn this new trick that they decide to follow your site.
Also, offer a newsletter feed. Use either a suitable plugin or a third party service for this. You are giving your readers stacks of choice as to how to keep updated, meaning they are more budding to keep reading and coming back, thus increasing your visitors!
