Hello... Jennifer, and everyone! I'm new here - thought I'd post a comment about something I'm experienced in... SEO.
Regarding a "new" blog, it is paramount to keep in mind that it takes many (many) months for the blog to become "trusted" by the search engines, particularly Google. It is also strongly "preferred" to have your own domain name, rather than a sub-domain of a blog host. In order for the blog to gain "authority," one must be consistent with the posts, both in the general nature of the blog, and the amount of unique content. And by "unique," I don't necessarily mean unique from other blogs... I mean avoiding a rehash of content previously posted in the same blog. (Though, feel free to rehash/reword and utilize in another blog later.)
It is VERY important to stick with the blog - the longer it exists and the more often it is updated, the more "authority" it will be earn. This is critical for the future - I see agents setting up blogs, then they get "busy" and abandon them, thinking they may not need the blog anymore. (They don't know what they're missing-out on later.) In this case, I'd hire a freelance copyright expert to create relevant content to keep the blog active. Also, assuming the content is generally helpful (note... I don't say necessarily 100% "accurate"), and important keywords are "naturally" included (conservatively peppered in each post), then the blog will prove quite valuable over the long haul. Moreover, do this with several "niche" or "hyper-local" blogs, and the benefit can be tremendous. (BTW, don't host multiple blogs on the same server/IP.)
The MOST important thing you can do in any blog post, is to have a keyword driven, and "eye-catching" heading, and a "custom" page title. For example, if I wrote 350 word post with comments on home staging, both headings below would work, but one would not only drive more human traffic, but be more successful from an SEO stand point...
Sample 1: Post Heading - "Home Staging Tips" Page Title - "Home Staging Tips"
Sample 2: Post Heading - "5 Quick Home Staging Tips for a Fast Sale" Page Title - "5 Quick Home Staging Tips - Stage a House to Sell Fast"
I came up with this very quickly... but obviously, Sample 2 is preferred. It's important to take advantage of the Blog's software to utilize the page title tag to its full potential. In the case of Sample 2, the heading is engaging, and the page title contains matching words and word order, and is also "concise" (goal to contain 10 words or less). Then, using this example, include the following words in the post one or two times (naturally - not blatantly repetitive)...
home, house, staging, stage, tips, sale, sell, quick, fast
and the following phrases only once...
home staging tips
quick home staging
stage a house
Anyway... just some "quick" advice.
When starting a blog, it's best to try to incorporate some of the basics above, so that as you become more experienced going forward, you don't feel compelled (or worse, find it vital) to spend ooodles of time, and then some, tweaking your previous posts.
Have a great day!
