      I have a client that recently read an article that advised him to break up his website into various URL's that targeted specific products. It was supposed to be a solution to gain footing in an already competitive industry. So rather than company.com with various pages targeting his products, he'd end up having multiple smaller sites:

      companyClothing.com

      companyShoes.com

      Etc.

      The article stated that by structuring your website this way, you were more likely to gain ranking in Google by targeting these niche markets.

      I wanted to know if this article was based on any facts. Are there any benefits to creating a new website that targets a specific niche market versus as a section of pages on a main website?

      I then began looking into structuring each of these product areas into subdomains, but the data out there is not definitive as to how subdomains are viewed by Google and other search engines - more specifically how subdomains benefit (or not!) the primary domain.

      So, in general, when a business targets many products and services that cover a wide range - what is the best way to structure the delivery of this info: multiple domains, single domain with folders/categories, or subdomains?  If single domain with folders/categories are not an option, how do subdomains stack up?

      Thanks in advance for your help/suggestions!

        I just posted this in another thread but believe that it applies here as well....

        ========================================

        Let me just call this... "logical speculation"....

        If you chop a domain's content in half and place it on two different websites, you have also just chopped all of the links, likes, mentions, etc in half.

        If you do that you should expect every ranking everywhere to drop - because you now have less domain authority - you cut it in half.

        ========================================

          Splitting a client's website into multiple domains could affect you in branding (unless you incorporate the brand name and the vertical you want to split into the domain).

          Subdomains only make sense if you really want to target different audiences and there is little chance of cross-over (i.e. there would be a slim chance that customers would overlap if you sell cosmetics on one domain and DYI products on another). The danger of subdomains is that if content is not properly managed, you will run into all sorts of content issues.

          I would rather focus on a single domain with a good product category structure, product pages and a good set of landing-/conversion pages to target the different verticals.

          I also think that a single domain will afford you better long-term value (both from a SEO and SEM perspective).

            As is often the case, I think it depends on your specific business and products. I have seen the niche site idea work extremely well, and not work at all. Something to really take into account when considering the multi-site option is: Do you have the resources to develop manage and market multiple sites?

            I am an in-house SEO for a company that just launched a micro-brand. They could have opted to put these new products on their existing Web site, but the products and customers were going to be vastly different than the core customer persona of the main site, although they are all church ministry related.

            Our main site is very large and I have advised that it would be better to separate out the three subsections of the site because, again, the customers of each leg of the business are completely different. We are in a highly competitive category too, so this makes it extremely hard to rank for important keywords because our messaging is trying to address three different businesses with one Website.

            If you have the resources to handle multiple sites, and you're in a competitive space, I'd say go for the niche sites. But beware of Exact Match Domains. Google is crackin' down!

            Hope this perspective helps a bit.

              I used to have a lot of hotdog stand websites... then built a big site that quickly  defeated all of them and most of their competitors.

              Who is kicking all of the ass out there right now?. The hotdog stands? Or, the big sites like wikipedia, about, amazon, ebay, ??

              If you are going to attack the US Navy which would you rather have?  One battleship or ten potato guns?

              I used to run subdomains and then redirected them into folders on the main site and the results have been kickass.  Kickass.

              There is always a question about how google is going to treat subdomains but there is never a question about how they are going to treat a big website.

              As far as conversions go and impressing your visitors.  Which is going to do a better job.. A hotdog stand or a supermarket?  Which will produce better shopping cart totals though cross selling?

              Your questions have been asked in this Q&A over and over again.  If you use search you will find lots of opinions that support the above?

                Do you need to include the top menu on every single page of the site in the code?

                When using     cache:     on google, and clicking on Text-only version, our site has the top menu gibberish on top? My feeling is that this take away SEO juice from our title and focus keyword. Our website is culinarydepotinc.com

                Getting the Titles and Headings Right on Product Pages. Userbility vs SEO

                Hey Mozzers, I am optimising a chaotic section of the site including many similar products. Writing unique content etc. The titles and urls were all over the place so my first job was to tidy them up so I could make some sense of the situation, especially as sometimes they didn't even match! I should point out were on Magento, so product name = Both the Heading and Title of the page, the meta title can be set separately. When i refer to title I mean both <title>and <h1></strong><br /><br />Before they existed as such<br />URL:  domain.com/200-x-0-5-g-rs-232-balance.html<br />TItle:   PC-1234 200 x 0.5g x 0.3 RS-232 Balance<br /><br />This format was (Product Code, Capacities, Resolutions, Accuracy, Product Title)<br /><br />The issue was all 60 products in a page followed this format. Navigating through the page was a nightmare and was just a jumble of numbers and highly confusing even to me who learnt what they all mean, especially when you had 8 products from the same range you got presented with<br /><br />APC-1234 200 x 0.5g x 0.3 RS-232 Balance<br />APC-1235 500 x 1g x 0.3 RS-232 Balance<br />APC-1236 1000 x 2g x 0.3 RS-232 Balance<br />APC-1238 5000 x 10g x 0.3 RS-232 Balance<br />APC-1239 10000 x 15g x 0.3 RS-232 Balance<br />APC-1210 20000 x 25g x 0.3 RS-232 Balance<br />APC-1211 50000 x 50g x 0.3 RS-232 Balance</p> <p>I changed them to something more user friendly.<br /><br />URL: domain.com/200g-precision-balance.html<br />Title: 200g Precision Balance<br /><br />This has seen the following benefits<br />- URL is now clear and means something to the user<br />- Product titles are easy to navigate and the page is more pleasing to the eye<br />- The jumble of numbers in the title are now all labelled and shown below each product listing in bullet point so the user can see the basic spec of a product without having to decipher any titles<br /><br />Upon reflection I has a couple of concerns I was hoping you could discuss, I am wondering if I have made the titles too simple.<br />1) I have no product code in the title<br />We have our own products manufactured and sell existing brands with their own product codes. Some of these can be lengthy. Adding them makes them hard to the eye and the page looked cramped.<br /><br />The codes are listed beneath each product title on category pages and on a list on the actual product page, but no where in the titles. <br /><br />2)None of our products have a brand listed in the title<br />None of the products on the site had brand names in anything but the images when i started and as such it snuck under my radar. But should i pre-fix all titles with a brand name?<br /><br />Should </p> <p>URL: domain.com/200g-precision-balance.html<br />Title: 200g Precision Balance</p> <p>become</p> <p>URL: domain.com/BRAND1-200g-precision-balance.html<br />Title: BRAND1 200g Precision Balance<br /><br />My instinct tells me to change things to include brands as its useful to the customer and should have an SEO benefit, but to leave out product codes as they are accessible to the customer where they are now and dont make things messy and unreadable.<br /><br />As always, thanks for the input!</p></title>

                SVG image files causing multiple title tags on page - SEO issue?

                Does anyone have any experience with SVG image files and on-page SEO? A client is using them and it seems they use the title tag in the same way a regular image (JPG/PNG) would use an image ALT tag. I'm concerned that search engines will see the multiple title tags on the page and that this will cause SEO issues. Regular crawlers like Moz flag it as a second title tag, however it's outside the header and in a SVG wrap so the crawlers really should understand that this is a SVG title rather than a second page title. But is this the case? If anyone has experience with this, I'd love to hear about it.

                ECommerce Product Meta Descriptions vs. Product Descriptions

                Wondering if using on-page product descriptions as the individual product meta descriptions is a best practice for an eCommerce site? Instead of writing two product descriptions (one regular and one meta), I am thinking if the product copy is SEO rich, we'd be good to use just the one for both purposes. Thoughts? Ideas? Suggestions? Seems that many companies follow this practice. Thanks!

                "And" vs "&"

                I blog for hotels and I am wondering whether it is best to have on a wordpress tagline the name of the hotel such as Holiday Inn and Suites vs Holiday Inn & Suites. In Google AdWords, the "and" keyword always beats out the "&" word in exact search. The "&" just always looks cleaner. Also, when I refer to the hotel within a blog post, should I use the "and" or "&" in the name? Please help me understand which is best for seo. Thank you!

                How long is too long for domain URL length?

                I noticed one of the negatively correlated ranking factors was length of URL.  I'm building a page from scratch, we are trying to rank for 'Minneapolis Fitness' and 'Minneapolis Massage'. Is www.minnnepolismassageandfitness.com  just ridiculously long?  Or does the exact match outweigh the penalty for URL length?
