My colleagues here at Dental Design have done a number of blogs highlighting the rise of the smartphone and the increase of mobile internet search. Just to summarise, mobile search is becoming an increasingly important factor for marketing agencies to consider – according to recent research mobile website visitors are likely overtake desktop/laptop users by 2014 – so we feel a mobile friendly website is a must!
Another factor that we have to take into consideration is mobile SEO – this blog highlights some of the “best practices” we are going to be implementing into our search engine optimisation work for mobiles.
- Use Google Adwords Keyword Tool, Google Webmaster Tools search query data and keywords in web analytics to better understand your mobile user. Compare mobile search volume, impressions and traffic to desktop search volume, impressions and traffic to determine which keywords and concepts are most relevant to a user accessing the site from a handheld device. Mobile users search differently, and if you don’t do separate keyword research, you could be missing opportunities.
- Build mobile site at domain.com/mobile. Buy and permanently redirect .mobi domain and permanently redirect all popular variations of mobile URLs to this subfolder. While m.domain.com subdomains are the most popular variations of mobile URLs, and any variation (including dotmobi) can be optimized for search, adding a subfolder instead of a subdirectory is the only option that uses the full trust and authority of the root domain, which could help in ranking. Not building a mobile site and only formatting desktop content could make your brand less visible in search engines for navigational queries from users looking for branded mobile content.
- Develop mobile site in HTML5 for smartphone and tablet users. Site should be text-based, with enough keyword-rich text to convey the relevance of the page to search engines. Use to ensure content is accessible to feature phone users and search engines. Mobile boilerplate is a standards-based HTML5 template for creating mobile web apps that works well for optimized mobile sites.
- Desktop pages should be made accessible to mobile searchers through handheld CSS. If desktop pages are transcoded on a separate URL, use canonical tags to pass link equity back to desktop pages with equivalent content. I believe there’s value in creating pages specifically for mobile users in addition to presenting desktop content, but if you decide to format your desktop content for mobile access, use canonical tags or handheld CSS or you may split the link equity between two URLs.
- Create unique and keyword-rich title tags for your mobile content that doesn’t exist on the desktop. This is a best practice in traditional SEO, but agencies who build mobile sites are usually not focused on mobile SEO and often miss the most basic building blocks of SEO.
- Do not block your mobile site from desktop or mobile crawlers with robots.txt. Identify duplicate content with canonical tags and allow both crawlers total access. Blocking a mobile site from traditional Googlebot with robots.txt could make it invisible to smartphone searchers entering navigational queries.
- Use canonical tags for all necessary duplicate content, including carrier-themed pages, which are common in mobile design and development. Not doing so could split a site’s link equity and make it more difficult for relevant content to rank.
- Build links from other mobile sites and desktop sites that discuss mobile content. Link equity is a ranking factor in mobile search, and not building links could make content less authoritative and less visible in search.
- Use tel link and unique mobile 800 numbers to track conversions separately on your mobile site. This won’t help in ranking, but it will allow for proper monetization of mobile search, which can help secure additional funds and facilitate the mobile SEO process.
- Avoid black hat tactics and schemes designed to artificially inflate ranking. True in white hat SEO, true in white hat mobile SEO. Black hat or gray hat SEO carries a high degree of risk for people who look to SEO best practices lists for their optimization advice. Doing it incorrectly could result in de-indexing, lost revenue, and public humiliation.
- Avoid drop down boxes without text equivalent. This is not just a mobile SEO best practice, but it’s more prevalent in mobile sites since designers are more text-averse.
- Create mobile sitemap(s) for mobile-specific content. It’s not necessary to put transcoded pages in the mobile sitemap. Some research (epub format) indicates that mobile sitemaps could help with faster indexing and ranking of mobile sites
- Verify site in Google and Bing Webmaster Tools, and exclude extraneous parameters that cause crawl problems. This could help the mobile site get indexed faster and reduce crawl problems.
- Include enough on-page text to convey relevance to search engines. Mobile usability gurus are in favor of eliminating text on mobile sites, but some keyword-rich text is necessary to convey the page’s relevance to search engines. Reduce, rather than eliminate on-page text.
- Optimize page speed. This is a best practice in traditional SEO as well, but Google sees speed as even more critical in mobile search. Additionally, this could result in a better user experience, which will result in more links, word of mouth and conversions.
- If possible, validate the site using Ready.mobi or the W3C Mobile OK validator. Validation by itself is not a significant factor in ranking, but can make the site more usable, which (like #21) will inspire repeat visits and links.
- Optimize social media profiles, images, maps (e.g. Google Places page(s)) and other mobile content for mobile-specific keywords. Optimizing images will help with Google Goggles and other mobile visual search or augmented reality search engines. Social users and local users are often mobile, so optimizing these assets for the words that mobile users are searching on increases relevance of the content and could make it more visible to this growing social local mobile (SoLoMo) segment.
