301, content, forward or sub-domain

[Sure]

What’s do you think is best for a related but different part of a business?

Example: I cut grass but want to add mower repairs, I want to take advantage of good keyword urls such as www .qualcastrepairs. com, www .flymorepairs. com, etc .
If I do this, as far as I can understand I then have three options for the new url
1. add a few pages of content.
2. forward them to my main site
3. add a 301 redirect

Are there any particular pros and cons I should consider for each?

or do I have “qualcastrepairs” and “flymorepairs” as sub domains, are these just as good as a proper domains for serp.

If you use multiple domains, host them on separate class-c IP's, and only cross-link sparingly, plus have unique content, you afford yourself the greatest opportunity for easy link-building.

For example: Let's say there are 3,000 free directories to submit to. Each one allows you one link to the root domain of your site. If you have 1 domain, regardless the number of subdomains, you can get a max of 3,000 links from here.

If, however, you have 4 domains, you now have 12,000 links available, which can target longer-tailed keywords for niche domination.

When interlinking from your own sites, you now have the opportunity to use link anchors of your choice in passing some link love. Having links from strongly topically related sites (of your own) is icing on the cake.

This approach is how many companies control a large portion of the top10 rankings on organic and product search pages.

Thanks webgeek, but what are host them on separate class-c IP's

Thanks webgeek, but what are

Blatantly stolen from another website, cause I was also interested to know.



An IP consist of 4 parts AAA.BBB.CCC.xxx - the first part is called A-class, the second part B-class and the third part C-class. So any IP under the last part will be in the same C-class. So for example:

123.123.123.1 and 123.123.123.2 are in the same C-class but
123.123.123.1 and 123.123.124.1 is in two different C-classes

Many smaller hosts only mange one single or very few C-classes and therefore makes it difficult to get multiple IPs in different C-classes if you host all your sites the same place. Larger hosts have many C-classes (I believe some even have almost full B-classes but unless you specifically request your various sites to be on different C-class IPs you still could end up on the same. It's usually not something hosts care about (in relation to SEO and linking)

[Sure]

If I don't intend linking the sites do I still need different c-class Ips?

[webgeek]

If possible, always spread sites around. If not possible (or cost prohibitive), and you're not interlinking, then don't worry about it and rock on.
