4 Ways the March 9th Algorithm Update Impacted Local Search
Posted by Joy Hawkins
There are a ton of algorithm updates that happen regularly but not too many that have a moderate-to-high impact on local businesses and those of us that do Local SEO. The algorithm update that happened on March 9th was one that had a clear impact on local businesses both organically and in the 3-pack. Even after only one day, I saw several clients who had data in Search Console that looked drastically different like this:
After spending many hours analyzing dozens of SERPs and comparing before-and-after screenshots, here are the top observations I have for what changed.
- In many cases, Google changed the description they are showing in the search results and are pulling from the text on the page instead of using the description tag. This is something Google has been doing a lot in the last couple years but it appears they are doing it even more now based on almost every SERP I looked at.
- Implicit searches (local queries that don’t contain the name of the location) appeared to have a more drastic change and, in most cases, became more localized. In this example, “car accident lawyer” is being searched from a zip code in Brooklyn. Previously, the results showed a variety of law firms in NYC but now they focus more on ones that are in Brooklyn specifically.
- The criteria for the organic filter changed. Google’s organic filter makes it so that one website doesn’t dominate the search results. It actively filters out pages belonging to the same domain (or affiliated sites) and often makes it so that a site is only listed once or twice in the search results. With this update, I saw tons of changes to what pages were filtered. In this example, this site only appeared once in the search results because the other page was filtered. After this update, the 2nd page became unfiltered.
In another example, Yelp had the top 2 organic results before the update but now they only have one (the other got filtered).
I have a client who only appeared once before and now shows up three times in the SERP for one of their main keywords.
- The SERP features changed for tons of queries. There are tons of different search features: Answer boxes, local packs, top stories etc. I noticed on tons of queries, the type of search features being displayed changed quite a bit. In this example for “ceramic braces nyc”, the results used to show a 3-pack but are now showing an answer-box.
In this example, a search for “home insurance” used to trigger a knowledge panel and then a local pack way lower on the page. After the update, the local pack moved to the top and Google added a “people also ask” box.
There were tons of other observations I made when analyzing dozens of search results but these were the top patterns I observed. I’ll be doing a bunch of testing on instances where I saw drops due to the algorithm update and publishing any successful tactics I discover in different blog posts on our site. Did you notice anything interesting after this algorithm update? If so, let me know about it in the comments.
