Tell your client he is on the right track with wanting to target long tail keywords (that will make his ego feel better) but that it's not so simple as adding one keyword to all the pages. After you choose which page to rank for "oak furniture" (my guess would be the home page or main oak furniture page), choose which long tail phrases containing oak furniture you want to rank for, then choose pages (if different from the main oak furniture page) that would be a good fit. For example, you may have different pages for "discount oak furniture" vs. "taking care of your oak furniture." Do the same with other variations like oak table, oak chair, etc. I would recommend doing this keyword research first and then taking that to the client with a plan of action. If this is too manual, try using your existing product browsing categories as top-level keywords (so all the oak chairs have "oak chair" in the title, etc). This will get you a bit more granular than just blanketing the site with the broadest possible term. Your client should still be prepared that only one or two pages from the site will rank for that broad of a term.

Hi Adnan, True local results revolve around cities, not counties, and inclusion in the local pack of results typically requires having a physical location in the city of search. Beyond this, you can develop content for additional cities where you're not physically located, and that could include content you develop for counties, too, if research indicates county terms are important in your niche, but the goal of this work would typically be organic visibility rather than visibility in Google's local pack of results. Hope this helps!
