Does Google change algorithm?

[idandone]

I read in Sphinn a post which say Google changes algorithm and now the text-anchor is less important.

I checked that issue with my tool and I noticed a slightly change in websites position.

However, I've looking the internet and I didn't find any reference by SEO expert or Google (Of course).
Did anybody encounter any surprising website position change?

a few weeks ago i was then surprised about my keyword positioning for a certain keyword which was already ranking no. 2 but and the other with kind of the same or related do also rank on first page in top 10..but that keyword just dropped it's positioning..though it maintained it's positioning for several weeks already....but still it dropped...so it's not surprising anymore if G will have a sudden change in algo...

Dont believe all that you read. All though my guess it is Google end goal to diminish the back link worth over time. it has been spammed since Google inception.

I agree. I've seen changes over the last bunch of years. There are some really big ones that they talk a ton about. But I also believe there are many small ones that are not discussed publicly happening all the time.
