Welcome to the Q&A Forum

I'm pretty new to all of this, my new website is starting to come along nicely in the SERPs, now appear on page 4 for my main key phrases were I didn't appear last week at all. I'm now on a mission to get myself ranked higher but my website is pretty much done... apart from the ongoing blogposts that I need to add, I'm a wedding photographer so every shoot is going on to it. My question, my blogposts aren't necessarily targeting my main key phrase, it might be mentioned once or twice but ultimately it'll most likely be the venue that steals the targeting. By adding the blogposts (I still have 36 to do) and using my keyphrase sparing, will this help to elevate me from page 4 in google? I know that I still need to build backlinks etc to but just something I can't seem to find an answer for on google hehe.

How do search engines view wording variances? I am trying to target Scottish Wedding Photographer but will google/bing etc be intelligent enough to see plurals, see the word Scotland instead of Scottish, photography instead of photographer? Also with rankings, I had a secondary phrase there to which I'm ranking sort of page 2-3 at the moment (the site is circa 3 months old) but finding that I'm nowhere with the Scottish phrase, I checked 30 pages of results and show nowhere, is this due to the competition for my phrase? My site is www.martinwardphotography.com
