As you probably know, bing® and Yahoo!® have been solidifying the plan for an alliance for search. The plans to migrate all accounts to the Microsoft adCenter are now in full swing. So, what does this mean to us as digital marketers?
To start, Yahoo! Search Marketing as well as Yahoo!’s organic search algorithms will no longer exist, and Bing’s Microsoft adCenter and organic algorithm’s will remain as the Unified Marketplace. Already Bing’s algorithm feeds both bing.com and yahoo.com search results. Currently 3.5 – 10% of PPC traffic on Yahoo! is being served via the adCenter platform. On the week of October 11th this number is expected to increase to 40% and an additional 30% will move over each subsequent week through the end of October.
Once combined, Yahoo! and Microsoft sites will represent upwards of 30% of U.S search market share.
Bing and Yahoo! currently own the following market share, and are projected to own upwards of 4.8 Billion monthly searches ‘“ factoring out overlap:

When: Transitions will be complete by the end of October, pre-Holiday season, and have already begun to roll-out week by week.
The Details:
For your natural search engine optimization efforts, Bing will now represent ~30% of your overall search query share, so we recommend that you consider the following:
- Compare your key traffic/revenue driving keywords listings & rankings on both Bing and Yahoo!, and determine if you may benefit from augmenting your organic efforts during this transition to offset anything you may stand to lose.
- Communicate potential impact of these changes to your team.
- Decide if you may benefit from supplementing your paid search efforts to offset any changes in forecasted traffic in the short, or long-term.
- If you aren’t already set-up on Bing’s Webmaster Tools, get set-up.
For your paid search accounts, work closely with your Yahoo! representative to ensure this transition goes smoothly and that any changes you need to make to accounts are addressed to preserve performance.
Some additional details on the paid search transition:
- You will not be able to specify either a Yahoo! or Microsoft site in our campaigns, but can opt into both or out of both as follows:

- Bing and Yahoo!’s pre-existing platforms are different in terms of geo-targeting, ad copy guidelines, keyword match types and versions, bidding, and how media budgets are handled. You should carefully address each of these key areas in transitioning your accounts.
These changes will affect your media budgets. Consider an increase your Bing budget by ~40 to 60% to maintain volume.

Geo-targeting: If you’re opted in to geo-targeting, Blue Moon Works will replicate your previous targets as closely as possible given these options.
- Microsoft adCenter ‘“ lets users geo-target by country/region, state/province, metro area or city.
- Yahoo! previously allowed market, country, state, DMA, city or zip.
Ad Copy: Only Headlines will need to be adjusted for this transition.
- Microsoft adCenter’s ad copy guidelines are very similar to Google’s ‘“ allowing 25 character titles, and 70 character descriptions.
- Yahoo! had allowed 40 character titles and 70 character descriptions.
Match Types & Bidding: Blue Moon Works will adjust bids to maintain your current level of investment as closely as possible during this transition.
- Microsoft adCenter allows users to bid on each variation of a keyword just as Google does (misspellings, singular, plural, etc.). In addition, it offers 3 match types: broad, phrase and exact ‘“ at the keyword level. Minimum bids in adCenter are $0.05.
- Yahoo! previously featured two types: standard (similar to exact) and advanced (similar to broad). Yahoo minimum bids were $0.01.
Other:
- Yahoo! account history does not carry over in the transition, so if you weren’t previously in adCenter, you’ll be starting fresh.
- Yahoo! reporting data will be available post-transition, so back-up your data soon.
- Mobile search ads will transition the same as paid search ads.
- This transition does not affect Yahoo! My Display or Bing Display advertising, which will remain unchanged. Bing is only providing Web, Image and Video results on Yahoo! Search. There are no plans to extend what Bing powers to include the Bing Shopping and Visual Search experiences on Yahoo!! Search.
The Transition:
- If you didn’t previously run ads in Bing, but did in Yahoo!, consider moving your account over to Bing adCenter and modify according to the above.
- If you were previously in Google, Bing and Yahoo!, consider using Google’s account structure as the base for expanding into Bing, rather than Yahoo!’s due to the similarities between Google and Bing set-up.
Post Transition:
- Actively monitor your account during the transition, and communicate any differences being experienced post-alliance.
- You can expect to see a difference in reporting (Yahoo! will no longer be a player) ‘“ specifically in impressions, cost per click data, and conversion rate fluctuations.
- Look out for more news on changes as the industry shifts to accommodate the Bing/Yahoo! Alliance!
