NEW YORK ( TheStreet) -- Amazon's ( AMZN) position as online retail giant was confirmed again as Black Friday shopping numbers were tallied and released Monday.

But beyond the 13% year-over-year Black Friday sales growth at Amazon, a few behind-the-scenes tech shops also had a strong showing during the Thanksgiving rush, which should translate to a big Cyber Monday boost.

eBay's ( EBAY) PayPal, Google's ( GOOG) revamped product search site and GSI Commerce ( GSIC), an online sales system provider, all enjoyed a rich slice of the action, said ThinkEquity's review of the e-commerce numbers from the weekend.

PayPal said it saw payment growth of 27% on Black Friday, up from the 20% rate a year ago. The online payment broker also said it saw greater than 300% growth in mobile transactions.

For Google, the introduction of Google Products gave the search giant an even stronger foothold in a competitive field that includes favorites like PriceGrabber and Microsoft's ( MSFT) Bing Shopping price comparison sites. Google Product search traffic was up 69% over year-ago numbers, according to ThinkEquity, which cited a report by Mercent.

Another big player in the online shopping arena is GSI, the name behind retail brands like Dick's Sporting Goods ( DKS), Cole Hahn and Aeropostale ( ARO) deals. GSI shares, which have been down 6% this year, have risen 3% in the past week as the company continues to sign on new retail customers, including Donna Karan International.
