The new smartphone crawler that Google has launched works cleverly by caching mobile redirects and potentially mobile pages too, but letting the desktop page rankings carry the day. In theory, as long as you have strong rankings for your desktop pages on mobile phones, then your mobile pages should soon be benefiting from those rankings, as long as page-to-page mobile redirects are in place. But that begs the question – what about feature phones? When you live in a tech-savvy community like most of us do, it is sometimes hard to remember that not everyone has smartphones. In fact, some studies in the US still showed that in June 2011, more than 50% of subscribers had yet to upgrade from a feature phone to a smartphone (See the colorful graph below.) Conventional wisdom and studies published by other groups all indicate that feature phone users are much less interested in mobile search than smartphone users are. Though it may be irrelevant for many mobile marketers, WAP still has … [Read more...] about Smartphone Vs. Mobile-Only Google Indexing
Ever since news of the Google-Twitter deal broke in early February 2015, there has essentially been radio silence. We know that the deal gives the search giant access to Twitter’s “firehose” of live tweet data — but, thus far, there has been no information released on what search results will look like once the deal is implemented “in the first half of this year“(which itself is already half over). To fill the information void, there has been plenty of speculation. But perhaps a better question than, “What will search results look like?” is, “How might Google use all the data that will come through that firehose?” Google already uses a highly sophisticated algorithm to determine which of millions of sites to serve up as results for any given search query. According to Google, there are over 200 “signals” — such as content freshness, region, and terms on site — that help determine each search’s … [Read more...] about What Signals From Twitter Does Google Care About?
Any SEO professional will tell you that server errors (defined as status codes in the 5xx range) on one’s website should be minimized. Generally speaking, if a page cannot be accessed by a search engine, it cannot be accessed by a user. Though server downtime is sometimes necessary to implement fixes and update websites, be sure to handle server downtime properly and serve a 503 response — but not for too long. But how exactly do server errors impact a site’s search engine optimization? What effects, if any, do server errors have on search engine visibility and rankings? In early 2015, the effects of a fresh index began to emerge. Our team collected data on 5xx errors and evaluated keyword rankings. The impacts were startling, specifically with 500 Internal Server Errors and 503 Service Unavailable Errors. When a 500 response was encountered, the page could immediately drop from ranking. When a 503 response was encountered, the impacts were not immediate, and the 503 … [Read more...] about A Super Fresh Google Index? Server Errors & Rankings Impacts
